Problems with fglrx

2007-11-11T23:35:47Z

Dukat: /* Troubles using software suspend */ SLUB

This page discusses issues with the ATI proprietary [[fglrx]] display driver.

== Known Troubles and Solutions ==

=== X-specific issues ===

==== upgrading xserver-xorg ====
ATI proprietary drivers version 8.21.7 and later work with x.org 6.9.

If you are running an older version (8.20.8) under Debian sid and you upgrade your xserver-xorg, apt will force you to remove any debian-packaged fglrx drivers (package fglrx-driver depends on x.org << 6.8.99). You can just download the driver from the ATI site and install after modifying the Debian packager script to allow dependencies to be satisfied by x.org 6.9, or just download 8.21.7 and install manually. See talk page for step-by-step commands.

After installing the fglrx driver, you can use module-assist to build the appropriate kernel module.

==== new Xorg ID Scheme ====
ATI proprietary drivers <=8.36.5 with xorg >=7.1.0-18 (==1.3.0.0) in Debian Sid and Fedora ([http://www.sidux.com/PNphpBB2-viewtopic-t-3162-postdays-0-postorder-asc.html Debian] and [http://www.phoronix.net/forums/showthread.php?t=2382 Fedora] Forum Entries)

Ubuntu feisty made their own xorg with the standard id of 7.2, to work around this issue.

Xorg has changed its ID Scheme in newer Versions, and fglrx cannot cope with that (Error message saying "[...] X version mismatch - detected X.org 1.3.-1.905, required X.org 7.1.0.0 [...]").

A binary hack solves the Problem [http://rage3d.com/board/showthread.php?s=4638d94143536f6acacbccd8f0443472&t=33889029 (rage3d.com Forum Entry)]. This is a very '''dirty''' solution, and is probably violating the ATI driver license.

Simply using the open source ati driver (or holding back the xorg upgrades) until a new driver is released, is suggested.

As of version 8.37.6, this issue is solved. No more binary hacking needed.

=== Kernel-specific troubles ===

Using ATI drivers <=8.21.7 with kernel >=2.6.15 needs a [http://marc.theaimsgroup.com/?l=linux-kernel&m=113429835515001&w=2 patch]. (see table below for detail.) If you can't compile the driver modules with 2.6.15 or later, you should apply this [http://www.ksp.sk/~rasto/fglrx_with_2.6.15.patch patch] instead.

If you do not use one of these patches, you may experience peculiar lockups of X. Try {{cmduser|fglrxinfo}} - if your shell hangs at the end of this command, you may have an issue and should try the patch or upgrade.

Although unproven, there is a substantial amount of user / developer concern that the above patches prevent hard lockups but do not provide full reliability with 2.6.15 and there are larger / redisgn issues preventing compatibility. These issues have been fixed with later ATI drivers (> 8.21.7) so you can simply upgrade if you are running a more modern kernel.

==== 2.6.23 ====
In 2.6.23 release cycle, config option CONFIG_SUSPEND_SMP got renamed to CONFIG_PM_SLEEP_SMP. fglrx uses this variable for disabling power management on older kernels. As a result, SMP users running 2.6.23 weren't able to resume properly (almost instant lockup in that rare case fglrx managed to show a few usable pixels. A [http://linux.derkeiler.com/Mailing-Lists/Kernel/2007-10/msg03437.html quick patch] is available.

=== No hardware acceleration ===

====Acceleration lost after driver update====
If you lose hardware acceleration after a driver update this can be caused by an old fglrx kernel module being loaded.

Check out {{path|1=/var/log/Xorg.0.log}} for a message like:
:<code>(WW) fglrx(0): Kernel Module version does *not* match driver.</code>
:<code>(EE) fglrx(0): incompatible kernel module detected - HW accelerated OpenGL will not work</code>

You can verify this yourself by looking at the version message some lines above. It should read something not matching the installed version like:
:<code>(II) fglrx(0): Kernel Module Version Information:</code>
:<code>(II) fglrx(0): Name: fglrx</code>
:<code>(II) fglrx(0): Version: 8.10.19</code>

The cause for this trouble might be that there resist multiple versions of the fglrx module within the kernel module search path. 
Go to {{path|1=/lib/modules/<your linux kernel version>/}} and type {{cmdroot|1=grep fglrx modules.dep}}. 
If grep finds multiple lines you nailed down the problem. All you have to do now is to delete any versions of the module (look at the filedate) but the most current one. Then run {{cmdroot|1=depmod}} and you are done.

{{HINT|Newer versions (8.21.7) of the fglrx module seem to be installed in the <code>extra/</code> subdirectory. 
Older versions (8.19.10) used to be located in the <code>kernel/drivers/char/drm/</code> subdirectory.}}

====GCC 3.4====
If the ATI driver works only without the hardware acceleration, take into consideration that {{path|fglrx_dri.so}} was linked against libstdc++.so.5 which may not be present if your system uses gcc-3.4.

To fix this, compile gcc-3.3.5 and copy <tt>libstdc++.so.5*</tt> to {{path|/usr/lib}} and update the dynamic linker cache via {{cmdroot|ldconfig}}.

Or install a compat package for your favorite distro. FC4 users can do:
:{{cmdroot|yum install libstdc++.so.5}}

====radeonfb framebuffer====
Another possible cause for broken hardware acceleration (2D and 3D) is the radeonfb framebuffer: Switching to vesafb or vesafb-tng is reported to solve the problem on some systems. Also it has proven helpful to not perform {{cmdroot|modprobe fglrx}} after boot but to have the module loaded via {{path|/etc/modules.autoload/kernel2.x}} at boottime instead.

====Perpetual Mesa GLX Indirect on Debian====
If you've done everything right and you're still seeing:

:{{cmduser|fglrxinfo}}
:{{cmdresult|display: :0.0 screen: 0}}
:{{cmdresult|OpenGL vendor string: Mesa project: www.mesa3d.org}}
:{{cmdresult|OpenGL renderer string: Mesa GLX Indirect}}
:{{cmdresult|OpenGL version string: 1.2 (1.5 Mesa 6.4.1)}}

try this:

:{{cmdroot|mkdir -p /usr/X11R6/lib/modules/dri}}
:{{cmdroot|ln -s /usr/lib/dri/fglrx_dri.so /usr/X11R6/lib/modules/dri}}

Thanks to Maciej Matysiak for the clear debug [http://lists.debian.org/debian-amd64/2006/02/msg00217.html here] and solution [http://lists.debian.org/debian-amd64/2006/02/msg00311.html here].

More generally, use LIBGL_DEBUG=verbose fglrxinfo, to see what's happening, and whether you get this:
:{{cmduser|<nowiki>LIBGL_DEBUG=verbose</nowiki> fglrxinfo}}
:{{cmdresult|libGL: XF86DRIGetClientDriverName: 8.26.18 fglrx (screen 0)}}
:{{cmdresult|libGL: OpenDriver: trying /usr/X11R6/lib/modules/dri/fglrx_dri.so}}
:{{cmdresult|libGL error: dlopen /usr/X11R6/lib/modules/dri/fglrx_dri.so failed (/usr/X11R6/lib/modules/dri/fglrx_dri.so: cannot open shared object file: No such file or directory)}}
:{{cmdresult|libGL error: unable to find driver: fglrx_dri.so}}
:{{cmdresult|display: :0.0 screen: 0}}
:{{cmdresult|OpenGL vendor string: Mesa project: www.mesa3d.org}}
:{{cmdresult|OpenGL renderer string: Mesa GLX Indirect}}
:{{cmdresult|OpenGL version string: 1.2 (1.5 Mesa 6.4.2)}}

instead of that:
:{{cmduser|<nowiki>LIBGL_DEBUG=verbose</nowiki> fglrxinfo}}
:{{cmdresult|libGL: XF86DRIGetClientDriverName: 8.26.18 fglrx (screen 0)}}
:{{cmdresult|libGL: OpenDriver: trying /usr/X11R6/lib/modules/dri/fglrx_dri.so}}
:{{cmdresult|libGL: XF86DRIGetClientDriverName: 8.26.18 fglrx (screen 0)}}
:{{cmdresult|drmOpenByBusid: busid is PCI:1:0:0}}
:{{cmdresult|drmOpenDevice: minor is 0}}
:{{cmdresult|drmOpenDevice: node name is /dev/dri/card0}}
:{{cmdresult|drmOpenDevice: open result is 4, (OK)}}
:{{cmdresult|drmOpenByBusid: drmOpenMinor returns 4}}
:{{cmdresult|drmOpenByBusid: drmGetBusid reports PCI:1:0:0}}
:{{cmdresult|Can't open configuration file /home/merlin/.drirc: No such file or directory.}}
:{{cmdresult|fglrx: DPD supported.}}
:{{cmdresult|display: :0.0 screen: 0}}
:{{cmdresult|OpenGL vendor string: ATI Technologies Inc.}}
:{{cmdresult|OpenGL renderer string: MOBILITY FIREGL T2 Pentium 4 (SSE2) (FireGL) (GNU_ICD)}}
:{{cmdresult|OpenGL version string: 2.0.5879 (8.26.18)}}

I have contacted ATI to add that info by default, the mesa guys to do that in glxinfo too, as well as the debian packager to fix the debian packaging bug (2006/07/22), so hopefully the situation will improve soon

You may have to run fglrxinfo as root to get this detail rather than a useless message.

==== Where to look for fglrx_dri.so (gentoo and general)====
After installing a new kernel (linux-2.6.20-gentoo-r7) with gentoo I again was not able to get the ATI driver working
correctly. But now I found out what the problem was:

I tried
:{{cmduser|<nowiki>LIBGL_DEBUG=verbose</nowiki> fglrxinfo}}
:{{cmdresult|libGL: XF86DRIGetClientDriverName: 8.35.5 fglrx (screen 0)}}
:{{cmdresult|libGL: OpenDriver: trying /usr/lib32/dri/fglrx_dri.so}}
:{{cmdresult|libGL error: dlopen /usr/lib32/dri/fglrx_dri.so failed (/usr/lib32/dri/fglrx_dri.so: wrong ELF class: ELFCLASS32)}}
:{{cmdresult|libGL error: unable to find driver: fglrx_dri.so}}

The error itself makes sense, because I am running a 64-Bit linux on AMD. The question was, why libGL tries to look
in /usr/lib32 only...

After some digging around I found out, that apparently 8.35.5 version of the driver uses the environment variable
'''LIBGL_DRIVERS_PATH''' to find out where it should look for the "fglrx_dri.so" driver.

Now in my case this environment variable pointed to "/usr/lib32/dri" and that was what caused the problem.
So doing
:{{cmduser|<nowiki>export LIBGL_DRIVERS_PATH='/usr/lib64/dri:/usr/lib32/dri'</nowiki>}}
solved the problem in my case.

As mentioned I use gentoo. After some more digging around I found out, that it is apparently necessary to call
:{{cmduser|env-update}}
after a re-install of the ATI driver. To be more specific, it seems that "eselect opengl set ati" sometimes
does something wrong. "env-update" seems to repair the problem so that afterwards the '''LIBGL_DRIVERS_PATH'''
environment variable is set correctly when you log in.

If you want to check, look in <code>/etc/profile.env</code> and <code>/etc/profile.csh</code>. This is the
place where the '''LIBGL_DRIVERS_PATH''' environment variable gets set.

=== Softlink hell ===
The [[fglrx]] installer replaces the standard X.org OpenGL implementation (Mesa) with its own files, potentially causing collisions with the distribution's file and package management. It is best to install the driver via a package built for your distribution, which will typically include the necessary kludges to make things work. See the [[fglrx]] page for pointers.

====Discussion====
If using {{cmduser|fglrxinfo}} after installing [[fglrx]] indicates that you are still using the mesa indirect software GL renderer, you likely have some misplaced softlinks. It seems like it has to do with an apt-get upgrade that sometimes replaces these links. Anyway, go to
:{{cmdroot|cd /usr/X11R6/lib}}
and list your GL libraries and links
:{{cmdroot|ls -la *GL*}}
You should see something like the following two lines amoung others:
:{{cmdresult|libGL.so -> libGL.so.1.2}}
:{{cmdresult|libGL.so.1 -> libGL.so.1.2}}
If you see a link to a mesa library (something like {{cmdresult|... -> libGL.mesa.1.2}}), then that's your problem! Restore the softlink like this (use your actual library version, though):
:{{cmdroot|ln -s libGL.so.1.2 libGL.so.1}}

For some reason, this link might "break" later, giving you the software rendering once more. Even after renaming the mesa library to something like <tt>mesa.bkup</tt>, the system might still find it and link to it despite the name change. If you have to do this a lot, you could write a restoreGL script.

=====Gentoo=====
{{Gentoo}} has built in tools for managing the OpenGL symlinks.
:{{cmdroot|eselect opengl set ati}}
If <tt>eselect opengl ati</tt> doesn't fix it for you, you should probably tell [http://bugs.gentoo.org Gentoo Bugzilla] (assuming they don't know yet).

If {{cmdroot|ldd /usr/X11R6/bin/glxinfo}} shows that your system still uses the xorg-x11 mesa libs after trying one of the above commands, i.e. a line like this:
:{{cmdresult|1=libGL.so.1 => /usr/lib/opengl/xorg-x11/lib/libGL.so.1 (0x400a8000)}}
you will also need to relink {{path|libGl.so.1.2}}:
:{{cmdroot|cd /usr/lib/opengl/xorg-x11/lib/}}
:{{cmdroot|mv libGL.so.1.2 libGL.so.1.2_backup}}
:{{cmdroot|ln -s /usr/lib/libGL.so.1.2 libGL.so.1.2}}
After another restart of X {{cmduser|fglrxinfo}} should show that it's using the right libs now.

=====Debian=====

:{{cmdroot|rm /usr/lib/libGL.so*}}
:{{cmdroot|rm /usr/X11R6/lib/libGL.so*}}
:{{cmdroot|cd /usr/X11R6/lib}}
:{{cmdroot|cp /usr/lib/fglrx/diversions/lib/libGL.so.1.2 .}}
:{{cmdroot|ln -s libGL.so.1.2 libGL.so.1}}
:{{cmdroot|ldconfig}}

=== Troubles using software suspend ===

Suspend won't work on any distribution which has activated the new SLUB allocator with fglrx < 8.42. This affects e.g. Ubuntu 7.10 Gutsy (see https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/121653/). The only workaround is currently to compile a custom kernel with SLAB support!

When the computer resumes from suspend, X only displays a garbled image and the computer is frozen.
The problem is acknowledged in ATI's release notes and in knowledge base entry <strike>[https://support.ati.com/ics/support/KBResult.asp?searchFor=Search+Words&search.x=0&search.y=0&searchOption=id&questionID=737-218+&task=knowledge&searchTime=-1&productID=&folderID=-1&resultLimit=50 737-218]</strike> [https://support.ati.com/ics/support/KBAnswer.asp?questionID=218 737-218]. Driver version 8.19.10 has "initial support for Suspend and Resume" but is working very nicely for most people (verified on T43, T43p and T42) without vbetool.

If you are using an older version of fglrx, using [http://www.srcf.ucam.org/~mjg59/vbetool/ vbetool] to save/restore the video card state before/after suspend worked for some people. If you use [[Software Suspend 2|Software Suspend 2 (suspend2)]] scripts, you can simply uncomment <tt>EnableVbetool yes</tt> in {{path|/etc/hibernate/hibernate.conf}}. Be aware though that it breaks suspend/resume for drivers beginning with version 8.19.10, so remember to disable it again when upgrading.

=== Troubles with large RAM ===
Version 8.14.13 (and probably earlier versions) of the driver does not seem to be able to cope with large amounts of RAM: with 512 MB it works, with 1.5 GB it crashes the machine as soon as X is started. The problem is present only if the <tt>fglrx</tt> kernel module is loaded, but independently of whether {{kernelconf|CONFIG_HIGHMEM||||||}} is enabled. A workaround is to limit RAM by adding the {{bootparm|mem|864m}} kernel parameter.

Version 8.16.20 fixes the problem.

===Display switching ===
The switching between internal and external display doesn't work with fglrx versions <= 8.24.8, because the driver blocks messing around with the chipset via ACPI. If you want to use this feature (i.e. during presentations), you should use the <tt>vesa</tt> server instead (experienced with a R52, Kernel 2.6.11, xorg 6.8.2, fglrx 8.16.20). Or boot notebook with CRT connected, it will automatically detect it and display on both.

===Composite Support===
ATI, as of fglrx 8.42.3 added composite windowing (alpha channel), enabling hardware accelerated translucent windows (primarily for 'eye candy.') This has not been tested yet, and reports will be added here as users evaluate this versus the R300 open source drivers.

For reference, some discussion of current status of drivers can be found in the Rage3d forums' (http://rage3d.com/board) Linux area.

Composite support is also supported with recent Mesa and Xorg > 7 with the open source 3d radeon / R300 drivers found in the linux kernel or debian's driver repository. It works with the [[R300]] / FireGL T2 series as found on the T43p extremely well. This has made rapid progress in speed with the latest few releases, and as of kernel 2.6.23 runs perfectly well with an R300 based card.

===Hardlock on X logout===
Up from driver version 8.19.10 you will experience a system hard lock when logging out from X, if the session manager (kdm/gdm) is not properly configured. You have to tell the session manager to restart X.

In the kdm config file (gentoo: {{path|/usr/kde/<VERSION>/share/config/kdm/kdmrc}}) you have to add following to the section <code>[X-:*-Core]</code>:
TerminateServer=true

In the gdm config (/etc/gdm/gdm.conf) file add the following to the daemon-section:
AlwaysRestartServer=true

Information from the ATI bugtracker: http://ati.cchtml.com/show_bug.cgi?id=239

Another reason of hardlock my be using the wrong AGP driver. Make sure that you have proper drivers for your motherboard loaded before fglrx: (gentoo: {{path|/etc/modules.autoload.d/kernel-2.6}}):
intel-agp
fglrx

A common problem seems to be mistakenly using ATI Chipset drivers instead of Intel.

Information from gentoo bugtracker: <s>[http://bugs.gentoo.org/show_bug.cgi?id=113685 113685]</s>. Fixed in 8.25.18

===Cannot switch to VT===

With usplash boot enabled, it may not be possible to switch to a VT from X (Using Alt+Fn). Tested on T60p (Mobility Fire GLV5200) on Ubuntu 6.06 / 6.10 and fglrx 8.25.18 / 8.28.8. Display may become garbled and system might freeze. Solution (testet on Ubuntu 6.10) is to either remove the "splash" kernel boot parameter or add "vga=791" parameter ("vga=794" can be used on 1400x1050 panel).

===Flickering Display===

Some people have reported problems with their display flickering when using ati-drivers newer than 8.14.13. The problem is unclear
(possibly associated with an incorrect modeline setting) and no known solution exists except to use the open source radeon drivers.
You can follow this problem here: http://ati.cchtml.com/show_bug.cgi?id=248

===Error messages in system log===

If you find something like the following in {{path|/var/log/messages}}:

:{{cmdresult|kernel: mtrr: base(0xc0000000) is not aligned on a size(0x7ff0000) boundary}}
:{{cmdresult|kernel: [fglrx:firegl_addmap] *ERROR* mtrr allocation failed (-22)}}
:{{cmdresult|kernel: [fglrx:firegl_unlock] *ERROR* Process 5132 using kernel context 0}}

try to execute the following line and reload the fglrx module:

:{{cmdroot|1=echo "base=0xd0000000 size=0x8000000 type=write-combining" > /proc/mtrr}}

More detailed instructions can be found [http://ubuntuforums.org/showthread.php?t=115104 here].

===Hang when logging out===

A common problem is that when logging out from X, instead of gettign the KDM or GDM prompt, the system hangs.

This is discussed, including workarounds here: http://ati.cchtml.com/show_bug.cgi?id=239

===No power saving when CRT in use===

When both CRT and LCD are in use, power saving cannot be enabled.

===WineX / Cedega Installs Software But Errors on Loading Games===

Some users may experience problems with certain FIREGL cards (in my case an ibm t43p laptop with a v3200 ati firegl) whereby projects such as cedega and wine refuse to work with 3d graphics, but native binaries (e.g. quake 4) work fine. A possible workaround is to add the following line in the drivers section of your /etc/X11/xorg.conf

Option "UseFastTLS" "2"

This option used to be configured with the older ati drivers when you ran "fglrxconfig". I have not yet found a way to get it to appear with "aticonfig", hence the manual insertion. This option is good for several linux distros I have tried, fedora core 5, ubuntu dapper and suse 10.1. It does not appear to effect performance on natively run programs.

{{NOTE|This may cause problems on machines with a Linux kernel version of 2.6.20 or higher (observed choppy video and video color inversion on T60p with both 2.6.20 and 2.6.21).}}

===Line Appears Below Mouse Cursor===

Some users have reported seeing a line approximately 1 mouse height below the bottom edge of the cursor, which follows the mouse and appears to change color based on the image below the cursor. This has been seen to happen using fglrx without the kernel module installed (in 2D mode) and additionally on external displays or multiple X servers. To work around the problem, try disabling the DGA extension by making the following changes to your XFree86.conf or xorg.conf file. Replace (or comment-out)
Load "extmod"
with
SubSection "extmod"
Option "omit xfree86-dga"
EndSubSection

===Freeze while using OpenGL Apps===

Some OpenGL applications such as screensavers or games (SecondLife) cause freezes. The cursor still moves, but otherwise the machine is unresponsive. This is the case with Xorg 7.1 and fglrx 8.29.6 using an x1400 and other cards. The solution is to add the following options to the video Device section in xorg.conf:
Option "Capabilities" "0x00000800"
Option "KernelModuleParm" "locked-userpages=0"

===Xv doesn't work correctly with drivers >= 8.36 and Xyyyy-cards===

See [http://ati.cchtml.com/show_bug.cgi?id=677] for further information. It seems as if only Xyyyy-cards are affected. Problem: graphical glitches with mplayer, programs like xine and totem might not start up at all. 8.35 doesn't seem to be affected

===Floating Point Exception with various X apps===

When the X server is left to autodetect the DPI, the fglrx driver may fail to supply the monitor dimensions. Video output switching may contribute to this bug.

Problems were experienced on T42p with Ubuntu 7.04, xorg-driver-fglrx 7.1.0-8.34.8+2.6.20.5-16.29.

This can be observed with xdpyinfo

:{{cmduser|xdpyinfo | grep dimensions}}
:{{cmdresult|dimensions: 1280x1024 pixels (0x0 millimeters)}}

Many applications will use the screen size and attempt to calculate DPI, resulting in a divide by zero operation and a SIGFPE.

A work around is to supply the dimensions in /etc/X11/xorg.conf. Use the DisplaySize parameter within your monitor's configuration. For example:

Section "Monitor"
Identifier "Generic Monitor"
HorizSync 28.0 - 64.0
VertRefresh 43.0 - 60.0
Option "DPMS"
DisplaySize 433 351

Problems with fglrx

2006-10-27T23:23:23Z

Dukat: /* Cannot switch to VT */

This page discusses issues with the ATI proprietary [[fglrx]] display driver.

== Known Troubles and Solutions ==

=== X-specific issues ===

ATI proprietary drivers version 8.21.7 and later work with x.org 6.9.

If you are running an older version (8.20.8) under Debian sid and you upgrade your xserver-xorg, apt will force you to remove any debian-packaged fglrx drivers (package fglrx-driver depends on x.org << 6.8.99). You can just download the driver from the ATI site and install after modifying the Debian packager script to allow dependencies to be satisfied by x.org 6.9, or just download 8.21.7 and install manually. See talk page for step-by-step commands.

After installing the fglrx driver, you can use module-assist to build the appropriate kernel module.

=== Kernel-specific troubles ===

Using ATI drivers <=8.21.7 with kernel >=2.6.15 needs a [http://marc.theaimsgroup.com/?l=linux-kernel&m=113429835515001&w=2 patch]. (see table below for detail.) If you can't compile the driver modules with 2.6.15 or later, you should apply this [http://www.ksp.sk/~rasto/fglrx_with_2.6.15.patch patch] instead.

If you do not use one of these patches, you may experience peculiar lockups of X. Try {{cmduser|fglrxinfo}} - if your shell hangs at the end of this command, you may have an issue and should try the patch or upgrade.

Although unproven, there is a substantial amount of user / developer concern that the above patches prevent hard lockups but do not provide full reliability with 2.6.15 and there are larger / redisgn issues preventing compatibility. These issues have been fixed with later ATI drivers (> 8.21.7) so you can simply upgrade if you are running a more modern kernel.

=== No hardware acceleration ===

====Acceleration lost after driver update====
If you lose hardware acceleration after a driver update this can be caused by an old fglrx kernel module being loaded.

Check out {{path|1=/var/log/Xorg.0.log}} for a message like:
:<code>(WW) fglrx(0): Kernel Module version does *not* match driver.</code>
:<code>(EE) fglrx(0): incompatible kernel module detected - HW accelerated OpenGL will not work</code>

You can verify this yourself by looking at the version message some lines above. It should read something not matching the installed version like:
:<code>(II) fglrx(0): Kernel Module Version Information:</code>
:<code>(II) fglrx(0): Name: fglrx</code>
:<code>(II) fglrx(0): Version: 8.10.19</code>

The cause for this trouble might be that there resist multiple versions of the fglrx module within the kernel module search path. 
Go to {{path|1=/lib/modules/<your linux kernel version>/}} and type {{cmdroot|1=grep fglrx modules.dep}}. 
If grep finds multiple lines you nailed down the problem. All you have to do now is to delete any versions of the module (look at the filedate) but the most current one. Then run {{cmdroot|1=depmod}} and you are done.

{{HINT|Newer versions (8.21.7) of the fglrx module seem to be installed in the <code>extra/</code> subdirectory. 
Older versions (8.19.10) used to be located in the <code>kernel/drivers/char/drm/</code> subdirectory.}}

====GCC 3.4====
If the ATI driver works only without the hardware acceleration, take into consideration that {{path|fglrx_dri.so}} was linked against libstdc++.so.5 which may not be present if your system uses gcc-3.4.

To fix this, compile gcc-3.3.5 and copy <tt>libstdc++.so.5*</tt> to {{path|/usr/lib}} and update the dynamic linker cache via {{cmdroot|ldconfig}}.

Or install a compat package for your favorite distro. FC4 users can do:
:{{cmdroot|yum install libstdc++.so.5}}

====radeonfb framebuffer====
Another possible cause for broken hardware acceleration (2D and 3D) is the radeonfb framebuffer: Switching to vesafb or vesafb-tng is reported to solve the problem on some systems. Also it has proven helpful to not perform {{cmdroot|modprobe fglrx}} after boot but to have the module loaded via {{path|/etc/modules.autoload/kernel2.x}} at boottime instead.

====Perpetual Mesa GLX Indirect on Debian====
If you've done everything right and you're still seeing:

:{{cmduser|fglrxinfo}}
:{{cmdresult|display: :0.0 screen: 0}}
:{{cmdresult|OpenGL vendor string: Mesa project: www.mesa3d.org}}
:{{cmdresult|OpenGL renderer string: Mesa GLX Indirect}}
:{{cmdresult|OpenGL version string: 1.2 (1.5 Mesa 6.4.1)}}

try this:

:{{cmdroot|mkdir -p /usr/X11R6/lib/modules/dri}}
:{{cmdroot|ln -s /usr/lib/dri/fglrx_dri.so /usr/X11R6/lib/modules/dri}}

Thanks to Maciej Matysiak for the clear debug [http://lists.debian.org/debian-amd64/2006/02/msg00217.html here] and solution [http://lists.debian.org/debian-amd64/2006/02/msg00311.html here].

More generally, use LIBGL_DEBUG=verbose fglrxinfo, to see what's happening, and whether you get this:
:{{cmduser|<nowiki>LIBGL_DEBUG=verbose</nowiki> fglrxinfo}}
:{{cmdresult|libGL: XF86DRIGetClientDriverName: 8.26.18 fglrx (screen 0)}}
:{{cmdresult|libGL: OpenDriver: trying /usr/X11R6/lib/modules/dri/fglrx_dri.so}}
:{{cmdresult|libGL error: dlopen /usr/X11R6/lib/modules/dri/fglrx_dri.so failed (/usr/X11R6/lib/modules/dri/fglrx_dri.so: cannot open shared object file: No such file or directory)}}
:{{cmdresult|libGL error: unable to find driver: fglrx_dri.so}}
:{{cmdresult|display: :0.0 screen: 0}}
:{{cmdresult|OpenGL vendor string: Mesa project: www.mesa3d.org}}
:{{cmdresult|OpenGL renderer string: Mesa GLX Indirect}}
:{{cmdresult|OpenGL version string: 1.2 (1.5 Mesa 6.4.2)}}

instead of that:
:{{cmduser|<nowiki>LIBGL_DEBUG=verbose</nowiki> fglrxinfo}}
:{{cmdresult|libGL: XF86DRIGetClientDriverName: 8.26.18 fglrx (screen 0)}}
:{{cmdresult|libGL: OpenDriver: trying /usr/X11R6/lib/modules/dri/fglrx_dri.so}}
:{{cmdresult|libGL: XF86DRIGetClientDriverName: 8.26.18 fglrx (screen 0)}}
:{{cmdresult|drmOpenByBusid: busid is PCI:1:0:0}}
:{{cmdresult|drmOpenDevice: minor is 0}}
:{{cmdresult|drmOpenDevice: node name is /dev/dri/card0}}
:{{cmdresult|drmOpenDevice: open result is 4, (OK)}}
:{{cmdresult|drmOpenByBusid: drmOpenMinor returns 4}}
:{{cmdresult|drmOpenByBusid: drmGetBusid reports PCI:1:0:0}}
:{{cmdresult|Can't open configuration file /home/merlin/.drirc: No such file or directory.}}
:{{cmdresult|fglrx: DPD supported.}}
:{{cmdresult|display: :0.0 screen: 0}}
:{{cmdresult|OpenGL vendor string: ATI Technologies Inc.}}
:{{cmdresult|OpenGL renderer string: MOBILITY FIREGL T2 Pentium 4 (SSE2) (FireGL) (GNU_ICD)}}
:{{cmdresult|OpenGL version string: 2.0.5879 (8.26.18)}}

I have contacted ATI to add that info by default, the mesa guys to do that in glxinfo too, as well as the debian packager to fix the debian packaging bug (2006/07/22), so hopefully the situation will improve soon

You may have to run fglrxinfo as root to get this detail rather than a useless message.

=== Softlink hell ===
The [[fglrx]] installer replaces the standard X.org OpenGL implementation (Mesa) with its own files, potentially causing collisions with the distribution's file and package management. It is best to install the driver via a package built for your distribution, which will typically include the necessary kludges to make things work. See the [[fglrx]] page for pointers.

====Discussion====
If using {{cmduser|fglrxinfo}} after installing [[fglrx]] indicates that you are still using the mesa indirect software GL renderer, you likely have some misplaced softlinks. It seems like it has to do with an apt-get upgrade that sometimes replaces these links. Anyway, go to
:{{cmdroot|cd /usr/X11R6/lib}}
and list your GL libraries and links
:{{cmdroot|ls -la *GL*}}
You should see something like the following two lines amoung others:
:{{cmdresult|libGL.so -> libGL.so.1.2}}
:{{cmdresult|libGL.so.1 -> libGL.so.1.2}}
If you see a link to a mesa library (something like {{cmdresult|... -> libGL.mesa.1.2}}), then that's your problem! Restore the softlink like this (use your actual library version, though):
:{{cmdroot|ln -s libGL.so.1.2 libGL.so.1}}

For some reason, this link might "break" later, giving you the software rendering once more. Even after renaming the mesa library to something like <tt>mesa.bkup</tt>, the system might still find it and link to it despite the name change. If you have to do this a lot, you could write a restoreGL script.

=====Gentoo=====
{{Gentoo}} has built in tools for managing the OpenGL symlinks. They seem to be replacing the old tool with a new one, so one of the following should work for you:
:{{cmdroot|opengl-update ati}} or
:{{cmdroot|eselect opengl set ati}}
Eselect is new, and still ~x86 (as of the end of 2005), so you may not have it yet. <tt>opengl-update</tt> is the old tried-and-true method for managing the symlinks. If <tt>opengl-update</tt> doesn't fix it for you, you should probably tell [http://bugs.gentoo.org Gentoo Bugzilla] (assuming they don't know yet).

If {{cmdroot|ldd /usr/X11R6/bin/glxinfo}} shows that your system still uses the xorg-x11 mesa libs after trying one of the above commands, i.e. a line like this:
:{{cmdresult|1=libGL.so.1 => /usr/lib/opengl/xorg-x11/lib/libGL.so.1 (0x400a8000)}}
you will also need to relink {{path|libGl.so.1.2}}:
:{{cmdroot|cd /usr/lib/opengl/xorg-x11/lib/}}
:{{cmdroot|mv libGL.so.1.2 libGL.so.1.2_backup}}
:{{cmdroot|ln -s /usr/lib/libGL.so.1.2 libGL.so.1.2}}
After another restart of X {{cmduser|fglrxinfo}} should show that it's using the right libs now.

=====Debian=====

:{{cmdroot|rm /usr/lib/libGL.so*}}
:{{cmdroot|rm /usr/X11R6/lib/libGL.so*}}
:{{cmdroot|cd /usr/X11R6/lib}}
:{{cmdroot|cp /usr/lib/fglrx/diversions/lib/libGL.so.1.2 .}}
:{{cmdroot|ln -s libGL.so.1.2 libGL.so.1}}
:{{cmdroot|ldconfig}}

=== Troubles using software suspend ===
When the computer resumes from suspend, X only displays a garbled image and the computer is frozen.
The problem is acknowledged in ATI's release notes and in knowledge base entry <strike>[https://support.ati.com/ics/support/KBResult.asp?searchFor=Search+Words&search.x=0&search.y=0&searchOption=id&questionID=737-218+&task=knowledge&searchTime=-1&productID=&folderID=-1&resultLimit=50 737-218]</strike> [https://support.ati.com/ics/support/KBAnswer.asp?questionID=218 737-218]. Driver version 8.19.10 has "initial support for Suspend and Resume" but is working very nicely for most people (verified on T43, T43p and T42) without vbetool.

If you are using an older version of fglrx, using [http://www.srcf.ucam.org/~mjg59/vbetool/ vbetool] to save/restore the video card state before/after suspend worked for some people. If you use [[Software Suspend 2|Software Suspend 2 (suspend2)]] scripts, you can simply uncomment <tt>EnableVbetool yes</tt> in {{path|/etc/hibernate/hibernate.conf}}. Be aware though that it breaks suspend/resume for drivers beginning with version 8.19.10, so remember to disable it again when upgrading.

=== Troubles with large RAM ===
Version 8.14.13 (and probably earlier versions) of the driver does not seem to be able to cope with large amounts of RAM: with 512 MB it works, with 1.5 GB it crashes the machine as soon as X is started. The problem is present only if the <tt>fglrx</tt> kernel module is loaded, but independently of whether {{kernelconf|CONFIG_HIGHMEM||||||}} is enabled. A workaround is to limit RAM by adding the {{bootparm|mem|864m}} kernel parameter.

Version 8.16.20 fixes the problem.

===Display switching ===
The switching between internal and external display doesn't work with fglrx versions <= 8.24.8, because the driver blocks messing around with the chipset via ACPI. If you want to use this feature (i.e. during presentations), you should use the <tt>vesa</tt> server instead (experienced with a R52, Kernel 2.6.11, xorg 6.8.2, fglrx 8.16.20). Or boot notebook with CRT connected, it will automatically detect it and display on both.

===Composite Support===
ATI has not officially supported composite windowing (alpha channel) enabling hardware acclerated translucent windows (primarily for 'eye candy.') Enabling Composite in KDE and the fglrx driver results in a very pretty desktop but unacceptably slow performance on a T43p with ATI's FireGL T2. It is still unusable in its current state (as of driver 8.25.18).

ATI promises support in the future when composite is officially supported by Xorg. Discussion of current status of drivers can be found in the Rage3d forums' (http://rage3d.com/board) Linux area.

Composite support is now supported with recent Mesa and Xorg > 7 with the open source 3d radeon drivers (if you run debian unstable, you should be all set.) It works with the [[R300]] / FireGL T2 series as found on the T43p, but noticably slows down the system. This has made rapid progress in speed with the latest few releases and kernel 2.6.18, and is finally usable with an R300 based card. Expect drivers to improve in the future, but it seems that composite does require a very fast video card and system.

===Hardlock on X logout===
Up from driver version 8.19.10 you will experience a system hard lock when logging out from X, if the session manager (kdm/gdm) is not properly configured. You have to tell the session manager to restart X.

In the kdm config file (gentoo: {{path|/usr/kde/<VERSION>/share/config/kdm/kdmrc}}) you have to add following to the section <code>[X-:*-Core]</code>:
TerminateServer=true

In the gdm config file add:
AlwaysRestartServer=true

Information from the ATI bugtracker: http://ati.cchtml.com/show_bug.cgi?id=239

Another reason of hardlock my be using the wrong AGP driver. Make sure that you have proper drivers for your motherboard loaded before fglrx: (gentoo: {{path|/etc/modules.autoload.d/kernel-2.6}}):
intel-agp
fglrx

A common problem seems to be mistakenly using ATI Chipset drivers instead of Intel.

Information from gentoo bugtracker: http://bugs.gentoo.org/show_bug.cgi?id=113685

===Cannot switch to VT===

With usplash boot enabled, it may not be possible to switch to a VT from X (Using Alt+Fn). Tested on T60p (Mobility Fire GLV5200) on Ubuntu 6.06 / 6.10 and fglrx 8.25.18 / 8.28.8. Display may become garbled and system might freeze. Solution (testet on Ubuntu 6.10) is to either remove the "splash" kernel boot parameter or add "vga=791" parameter.

https://launchpad.net/distros/ubuntu/+source/usplash/+bug/63558

===Flickering Display===

Some people have reported problems with their display flickering when using ati-drivers newer than 8.14.13. The problem is unclear
(possibly associated with an incorrect modeline setting) and no known solution exists except to use the open source radeon drivers.
You can follow this problem here: http://ati.cchtml.com/show_bug.cgi?id=248

===Error messages in system log===

If you find something like the following in {{path|/var/log/messages}}:

:{{cmdresult|kernel: mtrr: base(0xc0000000) is not aligned on a size(0x7ff0000) boundary}}
:{{cmdresult|kernel: [fglrx:firegl_addmap] *ERROR* mtrr allocation failed (-22)}}
:{{cmdresult|kernel: [fglrx:firegl_unlock] *ERROR* Process 5132 using kernel context 0}}

try to execute the following line and reload the fglrx module:

:{{cmdroot|1=echo "base=0xd0000000 size=0x8000000 type=write-combining" > /proc/mtrr}}

More detailed instructions can be found [http://ubuntuforums.org/showthread.php?t=115104 here].

===Hang when logging out===

A common problem is that when logging out from X, instead of gettign the KDM or GDM prompt, the system hangs.

This is discussed, including workarounds here: http://ati.cchtml.com/show_bug.cgi?id=239

===No power saving when CRT in use===

When both CRT and LCD are in use, power saving cannot be enabled.

===WineX / Cedega Installs Software But Errors on Loading Games===

Some users may experience problems with certain FIREGL cards (in my case an ibm t43p laptop with a v3200 ati firegl) whereby projects such as cedega and wine refuse to work with 3d graphics, but native binaries (e.g. quake 4) work fine. A possible workaround is to add the following line in the drivers section of your /etc/X11/xorg.conf

Option "UseFastTLS" "2"

This option used to be configured with the older ati drivers when you ran "fglrxconfig". I have not yet found a way to get it to appear with "aticonfig", hence the manual insertion. This option is good for several linux distros I have tried, fedora core 5, ubuntu dapper and suse 10.1. It does not appear to effect performance on natively run programs.

===Line Appears Below Mouse Cursor===

Some users have reported seeing a line approximately 1 mouse height below the bottom edge of the cursor, which follows the mouse and appears to change color based on the image below the cursor. This has been seen to happen using fglrx without the kernel module installed (in 2D mode) and additionally on external displays or multiple X servers. To work around the problem, try disabling the DGA extension by making the following changes to your XFree86.conf or xorg.conf file. Replace (or comment-out)
Load "extmod"
with
SubSection "extmod"
Option "omit xfree86-dga"
EndSubSection

===Freeze while using OpenGL Apps===

Some OpenGL applications such as screensavers or games (SecondLife) cause freezes. The cursor still moves, but otherwise the machine is unresponsive. This is the case with Xorg 7.1 and fglrx 8.29.6 using an x1400 and other cards. The solution is to add the following options to the video Device section in xorg.conf:
Option "Capabilities" "0x00000800"
Option "KernelModuleParm" "locked-userpages=0"

=== Linux X.Org driver ===
Not supported by the Xorg radeon driver

It's a pitty... such a nice card!!!!!!! Yum! Yum!

==== ThinkPad LCD ====
Display on the internal LCD works as long as you set the monitor settings correctly. Changing the driver from "ati" to "vesa" in xorg.conf will start X but with a lower resolution than expected.

Full resolution can be achieved when all modelines are removed and mode 1600x1200 with depth 24 is selected.

==== External VGA port ====
Yes

==== SVideo port ====
No

==== DVI port ====
No (yes on Docking Station, working with [[fglrx]] driver

=== Proprietary ATI driver ===
Proprietary [[fglrx]] driver works since version 8.25.18, version 8.24.8 works by adding "ChipID 0x71c5" to the xorg.conf "Device" statement and fooling it into thinking it's a X1600 mobility (do this only as a last resort or if you're sure you have an older driver; it is fatal to version 8.25.18).

The new driver 8.25.18 seems to support the card, see
https://support.ati.com/ics/support/KBAnswer.asp?questionID=1643
(successfully tested with the provided autorun installation script on OpenSuSE 10.1, T60p with 15" display).

(K)ubuntu 6.06 comes with this driver and it works out of the box. However, it seems to have problems with VT Switching (Alt+Fn). Instead of switching to a console, X resets and goes back to the log in screen (This doesn't happen when using the [[vesa]] driver). The switching issue might be resolvable by setting ENABLE_LAPTOP_MODE=true in /etc/default/acpi-support, but it doesn't seem to help on all systems.

Also, the pointer gets garbled sometimes in X, but this is only a minor annoyance. Dual Head (Xinerama) also works with this driver, but don't use KDE control center to enable it (use the ATi tool or edit xorg.conf manually)

I have a feeling that this card gets in the way when trying to suspend to RAM (resuming with a complete blank screen, lights are blinking, but that's it), but this can also be caused by other means.

=== Linux kernel Framebuffer driver ===

Not supported.

Problems with fglrx

2006-07-18T00:20:19Z

Dukat: /* Troubles using software suspend */

This page discusses issues with the ATI proprietary [[fglrx]] display driver.

== Known Troubles and Solutions ==

=== X-specific issues ===

ATI proprietary drivers version 8.21.7 and later work with x.org 6.9.

If you are running an older version (8.20.8) under Debian sid and you upgrade your xserver-xorg, apt will force you to remove any debian-packaged fglrx drivers (package fglrx-driver depends on x.org << 6.8.99). You can just download the driver from the ATI site and install after modifying the Debian packager script to allow dependencies to be satisfied by x.org 6.9, or just download 8.21.7 and install manually. See talk page for step-by-step commands.

After installing the fglrx driver, you can use module-assist to build the appropriate kernel module.

=== Kernel-specific troubles ===

Using ATI drivers <=8.21.7 with kernel >=2.6.15 needs a [http://marc.theaimsgroup.com/?l=linux-kernel&m=113429835515001&w=2 patch]. (see table below for detail.) If you can't compile the driver modules with 2.6.15 or later, you should apply this [http://www.ksp.sk/~rasto/fglrx_with_2.6.15.patch patch] instead.

If you do not use one of these patches, you may experience peculiar lockups of X. Try {{cmduser|fglrxinfo}} - if your shell hangs at the end of this command, you may have an issue and should try the patch or upgrade.

Although unproven, there is a substantial amount of user / developer concern that the above patches prevent hard lockups but do not provide full reliability with 2.6.15 and there are larger / redisgn issues preventing compatibility. These issues have been fixed with later ATI drivers (> 8.21.7) so you can simply upgrade if you are running a more modern kernel.

=== No hardware acceleration ===

====Acceleration lost after driver update====
If you lose hardware acceleration after a driver update this can be caused by an old fglrx kernel module being loaded.

Check out {{path|1=/var/log/Xorg.0.log}} for a message like:
:<code>(WW) fglrx(0): Kernel Module version does *not* match driver.</code>
:<code>(EE) fglrx(0): incompatible kernel module detected - HW accelerated OpenGL will not work</code>

You can verify this yourself by looking at the version message some lines above. It should read something not matching the installed version like:
:<code>(II) fglrx(0): Kernel Module Version Information:</code>
:<code>(II) fglrx(0): Name: fglrx</code>
:<code>(II) fglrx(0): Version: 8.10.19</code>

The cause for this trouble might be that there resist multiple versions of the fglrx module within the kernel module search path. 
Go to {{path|1=/lib/modules/<your linux kernel version>/}} and type {{cmdroot|1=grep fglrx modules.dep}}. 
If grep finds multiple lines you nailed down the problem. All you have to do now is to delete any versions of the module (look at the filedate) but the most current one. Then run {{cmdroot|1=depmod}} and you are done.

{{HINT|Newer versions (8.21.7) of the fglrx module seem to be installed in the <code>extra/</code> subdirectory. 
Older versions (8.19.10) used to be located in the <code>kernel/drivers/char/drm/</code> subdirectory.}}

====GCC 3.4====
If the ATI driver works only without the hardware acceleration, take into consideration that {{path|fglrx_dri.so}} was linked against libstdc++.so.5 which may not be present if your system uses gcc-3.4.

To fix this, compile gcc-3.3.5 and copy <tt>libstdc++.so.5*</tt> to {{path|/usr/lib}} and update the dynamic linker cache via {{cmdroot|ldconfig}}.

Or install a compat package for your favorite distro. FC4 users can do:
:{{cmdroot|yum install libstdc++.so.5}}

====radeonfb framebuffer====
Another possible cause for broken hardware acceleration (2D and 3D) is the radeonfb framebuffer: Switching to vesafb or vesafb-tng is reported to solve the problem on some systems. Also it has proven helpful to not perform {{cmdroot|modprobe fglrx}} after boot but to have the module loaded via {{path|/etc/modules.autoload/kernel2.x}} at boottime instead.

====Perpetual Mesa GLX Indirect on Debian====
If you've done everything right and you're still seeing:

$ fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: Mesa project: www.mesa3d.org
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 (1.5 Mesa 6.4.1)

try this:

# mkdir -p /usr/X11R6/lib/modules/dri
# ln -s /usr/lib/dri/fglrx_dri.so /usr/X11R6/lib/modules/dri

Thanks to Maciej Matysiak for the clear debug [http://lists.debian.org/debian-amd64/2006/02/msg00217.html here] and solution [http://lists.debian.org/debian-amd64/2006/02/msg00311.html here].

=== Softlink hell ===
The [[fglrx]] installer replaces the standard X.org OpenGL implementation (Mesa) with its own files, potentially causing collisions with the distribution's file and package management. It is best to install the driver via a package built for your distribution, which will typically include the necessary kludges to make things work. See the [[fglrx]] page for pointers.

====Discussion====
If using {{cmduser|fglrxinfo}} after installing [[fglrx]] indicates that you are still using the mesa indirect software GL renderer, you likely have some misplaced softlinks. It seems like it has to do with an apt-get upgrade that sometimes replaces these links. Anyway, go to
:{{cmdroot|cd /usr/X11R6/lib}}
and list your GL libraries and links
:{{cmdroot|ls -la *GL*}}
You should see something like the following two lines amoung others:
:{{cmdresult|libGL.so -> libGL.so.1.2}}
:{{cmdresult|libGL.so.1 -> libGL.so.1.2}}
If you see a link to a mesa library (something like {{cmdresult|... -> libGL.mesa.1.2}}), then that's your problem! Restore the softlink like this (use your actual library version, though):
:{{cmdroot|ln -s libGL.so.1.2 libGL.so.1}}

For some reason, this link might "break" later, giving you the software rendering once more. Even after renaming the mesa library to something like <tt>mesa.bkup</tt>, the system might still find it and link to it despite the name change. If you have to do this a lot, you could write a restoreGL script.

=====Gentoo=====
{{Gentoo}} has built in tools for managing the OpenGL symlinks. They seem to be replacing the old tool with a new one, so one of the following should work for you:
:{{cmdroot|opengl-update ati}} or
:{{cmdroot|eselect opengl set ati}}
Eselect is new, and still ~x86 (as of the end of 2005), so you may not have it yet. <tt>opengl-update</tt> is the old tried-and-true method for managing the symlinks. If <tt>opengl-update</tt> doesn't fix it for you, you should probably tell [http://bugs.gentoo.org Gentoo Bugzilla] (assuming they don't know yet).

If {{cmdroot|ldd /usr/X11R6/bin/glxinfo}} shows that your system still uses the xorg-x11 mesa libs after trying one of the above commands, i.e. a line like this:
:{{cmdresult|1=libGL.so.1 => /usr/lib/opengl/xorg-x11/lib/libGL.so.1 (0x400a8000)}}
you will also need to relink {{path|libGl.so.1.2}}:
:{{cmdroot|cd /usr/lib/opengl/xorg-x11/lib/}}
:{{cmdroot|mv libGL.so.1.2 libGL.so.1.2_backup}}
:{{cmdroot|ln -s /usr/lib/libGL.so.1.2 libGL.so.1.2}}
After another restart of X {{cmduser|fglrxinfo}} should show that it's using the right libs now.

=====Debian=====

<pre>
# rm /usr/lib/libGL.so*
# rm /usr/X11R6/lib/libGL.so*
# cd /usr/X11R6/lib
# cp /usr/lib/fglrx/diversions/lib/libGL.so.1.2 .
# ln -s libGL.so.1.2 libGL.so.1
# ldconfig
</pre>

=== Troubles using software suspend ===
When the computer resumes from suspend, X only displays a garbled image and the computer is frozen.
The problem is acknowledged in ATI's release notes and in knowledge base entry <strike>[https://support.ati.com/ics/support/KBResult.asp?searchFor=Search+Words&search.x=0&search.y=0&searchOption=id&questionID=737-218+&task=knowledge&searchTime=-1&productID=&folderID=-1&resultLimit=50 737-218]</strike> [https://support.ati.com/ics/support/KBAnswer.asp?questionID=218 737-218]. Driver version 8.19.10 has "initial support for Suspend and Resume" but is working very nicely for most people (verified on T43, T43p and T42) without vbetool.

If you are using an older version of fglrx, using [http://www.srcf.ucam.org/~mjg59/vbetool/ vbetool] to save/restore the video card state before/after suspend worked for some people. If you use [[Software Suspend 2|Software Suspend 2 (suspend2)]] scripts, you can simply uncomment <tt>EnableVbetool yes</tt> in {{path|/etc/hibernate/hibernate.conf}}. Be aware though that it breaks suspend/resume for drivers beginning with version 8.19.10, so remember to disable it again when upgrading.

=== Troubles with large RAM ===
Version 8.14.13 (and probably earlier versions) of the driver does not seem to be able to cope with large amounts of RAM: with 512 MB it works, with 1.5 GB it crashes the machine as soon as X is started. The problem is present only if the <tt>fglrx</tt> kernel module is loaded, but independently of whether {{kernelconf|CONFIG_HIGHMEM||||||}} is enabled. A workaround is to limit RAM by adding the {{bootparm|mem|864m}} kernel parameter.

Version 8.16.20 fixes the problem.

===Display switching ===
The switching between internal and external display doesn't work with fglrx versions <= 8.24.8, because the driver blocks messing around with the chipset via ACPI. If you want to use this feature (i.e. during presentations), you should use the <tt>vesa</tt> server instead (experienced with a R52, Kernel 2.6.11, xorg 6.8.2, fglrx 8.16.20). Or boot notebook with CRT connected, it will automatically detect it and display on both.

===Composite Support===
ATI has not officially supported composite windowing (alpha channel) enabling hardware acclerated translucent windows (primarily for 'eye candy.') Enabling Composite in KDE and the fglrx driver results in a very pretty desktop but unacceptably slow performance on a T43p with ATI's FireGL T2. It is still unusable in its current state (as of driver 8.25.18).

ATI promises support in the future when composite is officially supported by Xorg. Discussion of current status of drivers can be found in the Rage3d forums' (http://rage3d.com/board) Linux area.

There were some rumors that composite support was fast with the open-source 2d accelerated drivers in x.org 7.0 (as opposed to 6.8.x). Alas, trying this gives better results than the proprietary drivers, but it is still too slow to be reasonably useful.

===Hardlock on X logout===
Up from driver version 8.19.10 you will experience a system hard lock when logging out from X, if the session manager (kdm/gdm) is not properly configured. You have to tell the session manager to restart X.

In the kdm config file (gentoo: {{path|/usr/kde/<VERSION>/share/config/kdm/kdmrc}}) you have to add following to the section <code>[X-:*-Core]</code>:
TerminateServer=true

In the gdm config file add:
AlwaysRestartServer=true

Information from the ATI bugtracker: http://ati.cchtml.com/show_bug.cgi?id=239

Another reason of hardlock my be using the wrong AGP driver. Make sure that you have proper drivers for your motherboard loaded before fglrx: (gentoo: {{path|/etc/modules.autoload.d/kernel-2.6}}):
intel-agp
fglrx

A common problem seems to be mistakenly using ATI Chipset drivers instead of Intel.

Information from gentoo bugtracker: http://bugs.gentoo.org/show_bug.cgi?id=113685

===Cannot switch to VT===

At least with a T60p (Mobility Fire GLV5200) on Kubuntu 6.06 and fglrx 8.25.18 it is not possible to switch to a VT from X (Using Alt+Fn); Display becomed dark and the system freezes. CTRL+ALT+BKSPCE doesn't return to console, instead X restarts (Seems to be a kdm configuration feature from Kubuntu). When trying to do console login only every second attempt succeeds, otherwise it yields a black display.

http://ati.cchtml.com/show_bug.cgi?id=37

===Flickering Display===

Some people have reported problems with their display flickering when using ati-drivers newer than 8.14.13. The problem is unclear
(possibly associated with an incorrect modeline setting) and no known solution exists except to use the open source radeon drivers.
You can follow this problem here: http://ati.cchtml.com/show_bug.cgi?id=248

===Error messages in system log===

If you find something like the following in {{path|/var/log/messages}}:

:{{cmdresult|kernel: mtrr: base(0xc0000000) is not aligned on a size(0x7ff0000) boundary}}
:{{cmdresult|kernel: [fglrx:firegl_addmap] *ERROR* mtrr allocation failed (-22)}}
:{{cmdresult|kernel: [fglrx:firegl_unlock] *ERROR* Process 5132 using kernel context 0}}

try to execute the following line and reload the fglrx module:

:{{cmdroot|1=echo "base=0xd0000000 size=0x8000000 type=write-combining" > /proc/mtrr}}

More detailed instructions can be found [http://ubuntuforums.org/showthread.php?t=115104 here].

===Hang when logging out===

A common problem is that when logging out from X, instead of gettign the KDM or GDM prompt, the system hangs.

This is discussed, including workarounds here: http://ati.cchtml.com/show_bug.cgi?id=239

===No power saving when CRT in use===

When both CRT and LCD are in use, power saving cannot be enabled.

This is reported here: http://ati.cchtml.com/show_bug.cgi?id=304

Problems with fglrx

Dukat: ATI VT Switch

This page discusses issues with the ATI proprietary [[fglrx]] display driver.

If you do not use one of these patches, you may experience peculiar lockups of X. Try {{cmduser|fglrxinfo}} - if your shell hangs at the end of this command, you may have an issue and should try the patch or upgrade.

Although unproven, there is a substantial amount of user / developer concern that the above patches prevent hard lockups but do not provide full reliability with 2.6.15 and there are larger / redisgn issues preventing compatibility. These issues have been fixed with later ATI drivers (> 8.21.7) so you can simply upgrade if you are running a more modern kernel.

=== No hardware acceleration ===

====Acceleration lost after driver update====
If you lose hardware acceleration after a driver update this can be caused by an old fglrx kernel module being loaded.

Check out {{path|1=/var/log/Xorg.0.log}} for a message like:
:<code>(WW) fglrx(0): Kernel Module version does *not* match driver.</code>
:<code>(EE) fglrx(0): incompatible kernel module detected - HW accelerated OpenGL will not work</code>

You can verify this yourself by looking at the version message some lines above. It should read something not matching the installed version like:
:<code>(II) fglrx(0): Kernel Module Version Information:</code>
:<code>(II) fglrx(0): Name: fglrx</code>
:<code>(II) fglrx(0): Version: 8.10.19</code>

The cause for this trouble might be that there resist multiple versions of the fglrx module within the kernel module search path. 
Go to {{path|1=/lib/modules/<your linux kernel version>/}} and type {{cmdroot|1=grep fglrx modules.dep}}. 
If grep finds multiple lines you nailed down the problem. All you have to do now is to delete any versions of the module (look at the filedate) but the most current one. Then run {{cmdroot|1=depmod}} and you are done.

{{HINT|Newer versions (8.21.7) of the fglrx module seem to be installed in the <code>extra/</code> subdirectory. 
Older versions (8.19.10) used to be located in the <code>kernel/drivers/char/drm/</code> subdirectory.}}

====GCC 3.4====
If the ATI driver works only without the hardware acceleration, take into consideration that {{path|fglrx_dri.so}} was linked against libstdc++.so.5 which may not be present if your system uses gcc-3.4.

To fix this, compile gcc-3.3.5 and copy <tt>libstdc++.so.5*</tt> to {{path|/usr/lib}} and update the dynamic linker cache via {{cmdroot|ldconfig}}.

Or install a compat package for your favorite distro. FC4 users can do:
:{{cmdroot|yum install libstdc++.so.5}}

====radeonfb framebuffer====
Another possible cause for broken hardware acceleration (2D and 3D) is the radeonfb framebuffer: Switching to vesafb or vesafb-tng is reported to solve the problem on some systems. Also it has proven helpful to not perform {{cmdroot|modprobe fglrx}} after boot but to have the module loaded via {{path|/etc/modules.autoload/kernel2.x}} at boottime instead.

====Perpetual Mesa GLX Indirect on Debian====
If you've done everything right and you're still seeing:

$ fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: Mesa project: www.mesa3d.org
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 (1.5 Mesa 6.4.1)

try this:

# mkdir -p /usr/X11R6/lib/modules/dri
# ln -s /usr/lib/dri/fglrx_dri.so /usr/X11R6/lib/modules/dri

Thanks to Maciej Matysiak for the clear debug [http://lists.debian.org/debian-amd64/2006/02/msg00217.html here] and solution [http://lists.debian.org/debian-amd64/2006/02/msg00311.html here].

=== Softlink hell ===
The [[fglrx]] installer replaces the standard X.org OpenGL implementation (Mesa) with its own files, potentially causing collisions with the distribution's file and package management. It is best to install the driver via a package built for your distribution, which will typically include the necessary kludges to make things work. See the [[fglrx]] page for pointers.

====Discussion====
If using {{cmduser|fglrxinfo}} after installing [[fglrx]] indicates that you are still using the mesa indirect software GL renderer, you likely have some misplaced softlinks. It seems like it has to do with an apt-get upgrade that sometimes replaces these links. Anyway, go to
:{{cmdroot|cd /usr/X11R6/lib}}
and list your GL libraries and links
:{{cmdroot|ls -la *GL*}}
You should see something like the following two lines amoung others:
:{{cmdresult|libGL.so -> libGL.so.1.2}}
:{{cmdresult|libGL.so.1 -> libGL.so.1.2}}
If you see a link to a mesa library (something like {{cmdresult|... -> libGL.mesa.1.2}}), then that's your problem! Restore the softlink like this (use your actual library version, though):
:{{cmdroot|ln -s libGL.so.1.2 libGL.so.1}}

For some reason, this link might "break" later, giving you the software rendering once more. Even after renaming the mesa library to something like <tt>mesa.bkup</tt>, the system might still find it and link to it despite the name change. If you have to do this a lot, you could write a restoreGL script.

=====Gentoo=====
{{Gentoo}} has built in tools for managing the OpenGL symlinks. They seem to be replacing the old tool with a new one, so one of the following should work for you:
:{{cmdroot|opengl-update ati}} or
:{{cmdroot|eselect opengl set ati}}
Eselect is new, and still ~x86 (as of the end of 2005), so you may not have it yet. <tt>opengl-update</tt> is the old tried-and-true method for managing the symlinks. If <tt>opengl-update</tt> doesn't fix it for you, you should probably tell [http://bugs.gentoo.org Gentoo Bugzilla] (assuming they don't know yet).

If {{cmdroot|ldd /usr/X11R6/bin/glxinfo}} shows that your system still uses the xorg-x11 mesa libs after trying one of the above commands, i.e. a line like this:
:{{cmdresult|1=libGL.so.1 => /usr/lib/opengl/xorg-x11/lib/libGL.so.1 (0x400a8000)}}
you will also need to relink {{path|libGl.so.1.2}}:
:{{cmdroot|cd /usr/lib/opengl/xorg-x11/lib/}}
:{{cmdroot|mv libGL.so.1.2 libGL.so.1.2_backup}}
:{{cmdroot|ln -s /usr/lib/libGL.so.1.2 libGL.so.1.2}}
After another restart of X {{cmduser|fglrxinfo}} should show that it's using the right libs now.

=====Debian=====

</pre>

=== Troubles using software suspend ===
When the computer resumes from suspend, X only displays a garbled image and the computer is frozen.
The problem is acknowledged in ATI's release notes and in knowledge base entry <strike>[https://support.ati.com/ics/support/KBResult.asp?searchFor=Search+Words&search.x=0&search.y=0&searchOption=id&questionID=737-218+&task=knowledge&searchTime=-1&productID=&folderID=-1&resultLimit=50 737-218]</strike> [https://support.ati.com/ics/support/KBAnswer.asp?questionID=218 737-218]. Driver version 8.19.10 has "initial support for Suspend and Resume" but is working very nicely for most people (verified on T43, T43p and T42) without vbetool.

If you are using an older version of fglrx, using [http://www.srcf.ucam.org/~mjg59/vbetool/ vbetool] to save/restore the video card state before/after suspend worked for some people. If you use [[Software Suspend 2|Software Suspend 2 (suspend2)]] scripts, you can simply uncomment <tt>EnableVbetool yes</tt> in {{path|/etc/hibernate/hibernate.conf}}. Be aware though that it breaks suspend/resume for drivers beginning with version 8.19.10, so remember to disable it again when upgrading.

=== Troubles with large RAM ===
Version 8.14.13 (and probably earlier versions) of the driver does not seem to be able to cope with large amounts of RAM: with 512 MB it works, with 1.5 GB it crashes the machine as soon as X is started. The problem is present only if the <tt>fglrx</tt> kernel module is loaded, but independently of whether {{kernelconf|CONFIG_HIGHMEM||||||}} is enabled. A workaround is to limit RAM by adding the {{bootparm|mem|864m}} kernel parameter.

Version 8.16.20 fixes the problem.

===Display switching ===
The switching between internal and external display doesn't work with fglrx versions <= 8.24.8, because the driver blocks messing around with the chipset via ACPI. If you want to use this feature (i.e. during presentations), you should use the <tt>vesa</tt> server instead (experienced with a R52, Kernel 2.6.11, xorg 6.8.2, fglrx 8.16.20). Or boot notebook with CRT connected, it will automatically detect it and display on both.

===Composite Support===
ATI has not officially supported composite windowing (alpha channel) enabling hardware acclerated translucent windows (primarily for 'eye candy.') Enabling Composite in KDE and the fglrx driver results in a very pretty desktop but unacceptably slow performance on a T43p with ATI's FireGL T2. It is still unusable in its current state (as of driver 8.25.18).

ATI promises support in the future when composite is officially supported by Xorg. Discussion of current status of drivers can be found in the Rage3d forums' (http://rage3d.com/board) Linux area.

There were some rumors that composite support was fast with the open-source 2d accelerated drivers in x.org 7.0 (as opposed to 6.8.x). Alas, trying this gives better results than the proprietary drivers, but it is still too slow to be reasonably useful.

===Hardlock on X logout===
Up from driver version 8.19.10 you will experience a system hard lock when logging out from X, if the session manager (kdm/gdm) is not properly configured. You have to tell the session manager to restart X.

In the kdm config file (gentoo: {{path|/usr/kde/<VERSION>/share/config/kdm/kdmrc}}) you have to add following to the section <code>[X-:*-Core]</code>:
TerminateServer=true

In the gdm config file add:
AlwaysRestartServer=true

Information from the ATI bugtracker: http://ati.cchtml.com/show_bug.cgi?id=239

Another reason of hardlock my be using the wrong AGP driver. Make sure that you have proper drivers for your motherboard loaded before fglrx: (gentoo: {{path|/etc/modules.autoload.d/kernel-2.6}}):
intel-agp
fglrx

A common problem seems to be mistakenly using ATI Chipset drivers instead of Intel.

Information from gentoo bugtracker: http://bugs.gentoo.org/show_bug.cgi?id=113685

===Cannot switch to VT===

At least with a T60p (Mobility Fire GLV5200) on Kubuntu 6.06 and fglrx 8.25.18 it is not possible to switch to a VT from X (Using Alt+Fn); Display becomed dark and the system freezes. CTRL+ALT+BKSPCE doesn't return to console, instead X restarts (Seems to be a kdm configuration feature from Kubuntu). When trying to do console login only every second attempt succeeds, otherwise it yields a black display.

http://ati.cchtml.com/show_bug.cgi?id=37

===Flickering Display===

Some people have reported problems with their display flickering when using ati-drivers newer than 8.14.13. The problem is unclear
(possibly associated with an incorrect modeline setting) and no known solution exists except to use the open source radeon drivers.
You can follow this problem here: http://ati.cchtml.com/show_bug.cgi?id=248

===Error messages in system log===

If you find something like the following in {{path|/var/log/messages}}:

:{{cmdresult|kernel: mtrr: base(0xc0000000) is not aligned on a size(0x7ff0000) boundary}}
:{{cmdresult|kernel: [fglrx:firegl_addmap] *ERROR* mtrr allocation failed (-22)}}
:{{cmdresult|kernel: [fglrx:firegl_unlock] *ERROR* Process 5132 using kernel context 0}}

try to execute the following line and reload the fglrx module:

:{{cmdroot|1=echo "base=0xd0000000 size=0x8000000 type=write-combining" > /proc/mtrr}}

More detailed instructions can be found [http://ubuntuforums.org/showthread.php?t=115104 here].

===Hang when logging out===

A common problem is that when logging out from X, instead of gettign the KDM or GDM prompt, the system hangs.

This is discussed, including workarounds here: http://ati.cchtml.com/show_bug.cgi?id=239

===No power saving when CRT in use===

When both CRT and LCD are in use, power saving cannot be enabled.

This is reported here: http://ati.cchtml.com/show_bug.cgi?id=304

Problems with fglrx

2006-07-17T23:58:08Z

Dukat: /* Troubles using software suspend - T60p */

This page discusses issues with the ATI proprietary [[fglrx]] display driver.

== Known Troubles and Solutions ==

=== X-specific issues ===

ATI proprietary drivers version 8.21.7 and later work with x.org 6.9.

If you are running an older version (8.20.8) under Debian sid and you upgrade your xserver-xorg, apt will force you to remove any debian-packaged fglrx drivers (package fglrx-driver depends on x.org << 6.8.99). You can just download the driver from the ATI site and install after modifying the Debian packager script to allow dependencies to be satisfied by x.org 6.9, or just download 8.21.7 and install manually. See talk page for step-by-step commands.

After installing the fglrx driver, you can use module-assist to build the appropriate kernel module.

=== Kernel-specific troubles ===

Using ATI drivers <=8.21.7 with kernel >=2.6.15 needs a [http://marc.theaimsgroup.com/?l=linux-kernel&m=113429835515001&w=2 patch]. (see table below for detail.) If you can't compile the driver modules with 2.6.15 or later, you should apply this [http://www.ksp.sk/~rasto/fglrx_with_2.6.15.patch patch] instead.

If you do not use one of these patches, you may experience peculiar lockups of X. Try {{cmduser|fglrxinfo}} - if your shell hangs at the end of this command, you may have an issue and should try the patch or upgrade.

Although unproven, there is a substantial amount of user / developer concern that the above patches prevent hard lockups but do not provide full reliability with 2.6.15 and there are larger / redisgn issues preventing compatibility. These issues have been fixed with later ATI drivers (> 8.21.7) so you can simply upgrade if you are running a more modern kernel.

=== No hardware acceleration ===

====Acceleration lost after driver update====
If you lose hardware acceleration after a driver update this can be caused by an old fglrx kernel module being loaded.

Check out {{path|1=/var/log/Xorg.0.log}} for a message like:
:<code>(WW) fglrx(0): Kernel Module version does *not* match driver.</code>
:<code>(EE) fglrx(0): incompatible kernel module detected - HW accelerated OpenGL will not work</code>

You can verify this yourself by looking at the version message some lines above. It should read something not matching the installed version like:
:<code>(II) fglrx(0): Kernel Module Version Information:</code>
:<code>(II) fglrx(0): Name: fglrx</code>
:<code>(II) fglrx(0): Version: 8.10.19</code>

The cause for this trouble might be that there resist multiple versions of the fglrx module within the kernel module search path. 
Go to {{path|1=/lib/modules/<your linux kernel version>/}} and type {{cmdroot|1=grep fglrx modules.dep}}. 
If grep finds multiple lines you nailed down the problem. All you have to do now is to delete any versions of the module (look at the filedate) but the most current one. Then run {{cmdroot|1=depmod}} and you are done.

{{HINT|Newer versions (8.21.7) of the fglrx module seem to be installed in the <code>extra/</code> subdirectory. 
Older versions (8.19.10) used to be located in the <code>kernel/drivers/char/drm/</code> subdirectory.}}

====GCC 3.4====
If the ATI driver works only without the hardware acceleration, take into consideration that {{path|fglrx_dri.so}} was linked against libstdc++.so.5 which may not be present if your system uses gcc-3.4.

To fix this, compile gcc-3.3.5 and copy <tt>libstdc++.so.5*</tt> to {{path|/usr/lib}} and update the dynamic linker cache via {{cmdroot|ldconfig}}.

:{{cmdroot|yum install libstdc++.so.5}}

====radeonfb framebuffer====
Another possible cause for broken hardware acceleration (2D and 3D) is the radeonfb framebuffer: Switching to vesafb or vesafb-tng is reported to solve the problem on some systems. Also it has proven helpful to not perform {{cmdroot|modprobe fglrx}} after boot but to have the module loaded via {{path|/etc/modules.autoload/kernel2.x}} at boottime instead.

====Perpetual Mesa GLX Indirect on Debian====
If you've done everything right and you're still seeing:

$ fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: Mesa project: www.mesa3d.org
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 (1.5 Mesa 6.4.1)

try this:

# mkdir -p /usr/X11R6/lib/modules/dri
# ln -s /usr/lib/dri/fglrx_dri.so /usr/X11R6/lib/modules/dri

Thanks to Maciej Matysiak for the clear debug [http://lists.debian.org/debian-amd64/2006/02/msg00217.html here] and solution [http://lists.debian.org/debian-amd64/2006/02/msg00311.html here].

:{{cmdresult|libGL.so.1 -> libGL.so.1.2}}
If you see a link to a mesa library (something like {{cmdresult|... -> libGL.mesa.1.2}}), then that's your problem! Restore the softlink like this (use your actual library version, though):
:{{cmdroot|ln -s libGL.so.1.2 libGL.so.1}}

For some reason, this link might "break" later, giving you the software rendering once more.

If {{cmdroot|ldd /usr/X11R6/bin/glxinfo}} shows that your system still uses the xorg-x11 mesa libs after trying one of the above commands, i.e. a line like this:
:{{cmdresult|1=libGL.so.1 => /usr/lib/opengl/xorg-x11/lib/libGL.so.1 (0x400a8000)}}
you will also need to relink {{path|libGl.so.1.2}}:
:{{cmdroot|cd /usr/lib/opengl/xorg-x11/lib/}}
:{{cmdroot|mv libGL.so.1.2 libGL.so.1.2_backup}}
:{{cmdroot|ln -s /usr/lib/libGL.so.1.2 libGL.so.1.2}}
After another restart of X {{cmduser|fglrxinfo}} should show that it's using the right libs now.

=== Troubles using software suspend ===
When the computer resumes from suspend, X only displays a garbled image and the computer is frozen.
The problem is acknowledged in ATI's release notes and in knowledge base entry <strike>[https://support.ati.com/ics/support/KBResult.asp?searchFor=Search+Words&search.x=0&search.y=0&searchOption=id&questionID=737-218+&task=knowledge&searchTime=-1&productID=&folderID=-1&resultLimit=50 737-218]</strike> [https://support.ati.com/ics/support/KBAnswer.asp?questionID=218 737-218]. Driver version 8.19.10 has "initial support for Suspend and Resume" but is working very nicely for most people (verified on T43, T43p and T42) without vbetool.

If you are using an older version of fglrx, using [http://www.srcf.ucam.org/~mjg59/vbetool/ vbetool] to save/restore the video card state before/after suspend worked for some people. If you use [[Software Suspend 2|Software Suspend 2 (suspend2)]] scripts, you can simply uncomment <tt>EnableVbetool yes</tt> in {{path|/etc/hibernate/hibernate.conf}}. Be aware though that it breaks suspend/resume for drivers beginning with version 8.19.10, so remember to disable it again when upgrading.

=== Troubles with large RAM ===
Version 8.14.13 (and probably earlier versions) of the driver does not seem to be able to cope with large amounts of RAM: with 512 MB it works, with 1.5 GB it crashes the machine as soon as X is started. The problem is present only if the <tt>fglrx</tt> kernel module is loaded, but independently of whether {{kernelconf|CONFIG_HIGHMEM||||||}} is enabled. A workaround is to limit RAM by adding the {{bootparm|mem|864m}} kernel parameter.

Version 8.16.20 fixes the problem.

===Display switching ===
The switching between internal and external display doesn't work with fglrx versions <= 8.24.8, because the driver blocks messing around with the chipset via ACPI. If you want to use this feature (i.e. during presentations), you should use the <tt>vesa</tt> server instead (experienced with a R52, Kernel 2.6.11, xorg 6.8.2, fglrx 8.16.20). Or boot notebook with CRT connected, it will automatically detect it and display on both.

===Composite Support===
ATI has not officially supported composite windowing (alpha channel) enabling hardware acclerated translucent windows (primarily for 'eye candy.') Enabling Composite in KDE and the fglrx driver results in a very pretty desktop but unacceptably slow performance on a T43p with ATI's FireGL T2. It is still unusable in its current state (as of driver 8.25.18).

ATI promises support in the future when composite is officially supported by Xorg. Discussion of current status of drivers can be found in the Rage3d forums' (http://rage3d.com/board) Linux area.

There were some rumors that composite support was fast with the open-source 2d accelerated drivers in x.org 7.0 (as opposed to 6.8.x). Alas, trying this gives better results than the proprietary drivers, but it is still too slow to be reasonably useful.

===Hardlock on X logout===
Up from driver version 8.19.10 you will experience a system hard lock when logging out from X, if the session manager (kdm/gdm) is not properly configured. You have to tell the session manager to restart X.

In the kdm config file (gentoo: {{path|/usr/kde/<VERSION>/share/config/kdm/kdmrc}}) you have to add following to the section <code>[X-:*-Core]</code>:
TerminateServer=true

In the gdm config file add:
AlwaysRestartServer=true

Information from the ATI bugtracker: http://ati.cchtml.com/show_bug.cgi?id=239

Another reason of hardlock my be using the wrong AGP driver. Make sure that you have proper drivers for your motherboard loaded before fglrx: (gentoo: {{path|/etc/modules.autoload.d/kernel-2.6}}):
intel-agp
fglrx

A common problem seems to be mistakenly using ATI Chipset drivers instead of Intel.

Information from gentoo bugtracker: http://bugs.gentoo.org/show_bug.cgi?id=113685

===Flickering Display===

Some people have reported problems with their display flickering when using ati-drivers newer than 8.14.13. The problem is unclear
(possibly associated with an incorrect modeline setting) and no known solution exists except to use the open source radeon drivers.
You can follow this problem here: http://ati.cchtml.com/show_bug.cgi?id=248

===Error messages in system log===

If you find something like the following in {{path|/var/log/messages}}:

:{{cmdresult|kernel: mtrr: base(0xc0000000) is not aligned on a size(0x7ff0000) boundary}}
:{{cmdresult|kernel: [fglrx:firegl_addmap] *ERROR* mtrr allocation failed (-22)}}
:{{cmdresult|kernel: [fglrx:firegl_unlock] *ERROR* Process 5132 using kernel context 0}}

try to execute the following line and reload the fglrx module:

:{{cmdroot|1=echo "base=0xd0000000 size=0x8000000 type=write-combining" > /proc/mtrr}}

More detailed instructions can be found [http://ubuntuforums.org/showthread.php?t=115104 here].

===Hang when logging out===

A common problem is that when logging out from X, instead of gettign the KDM or GDM prompt, the system hangs.

This is discussed, including workarounds here: http://ati.cchtml.com/show_bug.cgi?id=239

===No power saving when CRT in use===

When both CRT and LCD are in use, power saving cannot be enabled.

This is reported here: http://ati.cchtml.com/show_bug.cgi?id=304

=== ATI Mobility FireGL V5200 ===
This is a ATI video adapter

=== Features ===
* Chipset: ATI M56 - Similar to Radeon X1600
* PCI ID: 1002:71c4
* PCI Express x16
* 256 MB GDDR3-SDRAM video memory
</div>
|style="vertical-align:top" |
|}

=== Linux X.Org driver ===
Not supported by the Xorg radeon driver

It's a pitty... such a nice card!!!!!!! Yum! Yum!

==== ThinkPad LCD ====
Display on the internal LCD works as long as you set the monitor settings correct. Changing the driver from "ati" to "vesa" in xorg.conf will start X but with lower resolution than expected

Full resolution can be archived when all modelines are removed and mode 1600x1200 with depth 24 is selected

==== External VGA port ====
Yes

==== SVideo port ====
No

==== DVI port ====
No (yes on Docking Station, working with [[fglrx]] driver

=== Proprietary ATI driver ===
Proprietary [[fglrx]] driver works since version 8.25.18, version 8.24.8 works by adding "ChipID 0x71c5" to the xorg.conf "Device" statement and fooling it into thinking it's a X1600 mobility.

The new driver 8.25.18 seems to support the card, see
https://support.ati.com/ics/support/KBAnswer.asp?questionID=1643
(successfully tested with the provided autorun installation script on OpenSuSE 10.1, T60p with 15" display).

(K)ubuntu 6.06 comes with this driver and it works out of the box. However, it seems to have problems with VT Switching (Alt+Fn). Instead of switching to a console, X resets and goes back to the log in screen (This doesn't happen when using the [[vesa]] driver). Also, the pointer gets garbled sometimes in X, but this is only a minor annoyance. Dual Head (Xinerama) also works with this driver, but don't use KDE control center to enable it (use the ATi tool or edit xorg.conf manually)

I have a feeling that this card gets in the way when trying to suspend to RAM (resuming with a complete blank screen, lights are blinking, but that's it), but this can also be caused by other means.

=== Linux kernel Framebuffer driver ===

Not supported.

=== ThinkPads this chip may be found in ===

=== Pure ACPI events ===

A few keys can generate ACPI events of their own on certain ThinkPads, as long as they are masked off in the ibm-acpi hotkey's mask (or the hotkey feature is disabled in ibm-acpi).

If you want the ThinkPad's BIOS and ACPI methods to know about these keys being pressed, you probably want to leave them masked out from ibm-acpi, and use their non-HKEY events listed below, instead.

''Note: Tested on T60p with Ubuntu 6.06 LTS''

Most Thinkpads have a hardware sound mixer, thus the volumes buttons should work without configuration. However, this change is not reflected in the software mixer. tpb has a switch to enable software mixer support via OSS. The manual recommends this only for devices without a hardware mixer, but it also works for other hadware mixer enabled devices, even with the ALSA system. Just put MIXER ON in your {{path|/etc/tpbrc}} file and you can see the effect immediately in any ALSA mixer (e.g. kmix). For this to work you need write permissions to {{path|/dev/nvram}}.

===xmodmap configuration===
xmodmap enables you to edit the modifier map and keymap tables that are used to translate keycodes into keysyms.
Understood? Well, basically it allows you to give the X server a dictionary for the translation of keycodes like "97" into more human readable synonyms like "Home". This way xmodmap allows you to make the special keys of your keyboard known to X applications.

To discover the keycode that a certain keypress produces, use the tool {{cmduser|xev}}

Usually you should write your keycode-keysym associations into the file {{path|~/.Xmodmap}}. This file is usually read by the X session startup scripts of your system, so that the mappings automatically get included everytime you run the X server.

The {{path|~/.Xmodmap}} lines for our purpose are in the form of
keycode <keycode> = <keysym>

Load the assocation using the command

{{cmduser|xmodmap ~/.Xmodmap}}

(some configurations do this automatically upon X startup).

The following table shows the keycodes generated by the ThinkPad special keys and sensible keysyms to assign them to.
{| border="1" cellspacing="0" cellpadding="2"
|+ keycodes and recommended keysyms
! key !! keycode !! keysym
|-
| {{ibmkey|Access IBM|#495988}} or {{ibmkey|ThinkPad|#494949}} || 159 || ?
|-
| {{ibmkey|Backward|#494949}} || 234 || XF86Back or F19
|-
| {{ibmkey|Forward|#494949}} || 233 || XF86Forward or F20
|-
| {{ibmkey|Home|#494949}} || 178 || XF86HomePage
|-
| {{ibmkey|Search|#494949}} || 229 || XF86Search
|-
| {{ibmkey|Mail|#494949}} || 236 || XF86Mail
|-
| {{ibmkey|Favorites|#494949}} || 230 || XF86AddFavorite or XF86Favorites
|-
| {{ibmkey|Reload|#494949}} || 231 || XF86Reload
|-
| {{ibmkey|Abort|#494949}} || 232 || XF86Stop
|-
| {{key|Fn}} || 227 || F35
|}

Note: if you are running [[tpb]] you might need to add the line <tt>XEVENTS=off</tt> into your tpbrc to stop it from grabbing the key events and allow them to get through to X instead.

Note: XF86Forward and XF86Back do not work correctly in Firefox. You may want to map them to F19 and F20 instead if you use Firefox.

=====Using Caps Lock as Super L (Windows key)=====
You can easily use Caps Lock as Win key by adding the following in your ~/.Xmodmap:
! No Caps Lock
clear lock
! Caps Lock as Win key
add mod4 = Caps_Lock
=====NumLock=====
On the ThinkPad {{X21}}, {{T21}}, {{T30}}, {{X31}}, {{T43}}, {{R51}} and possibly other models, X does not recognize the keycode for {{key|NumLk}} = {{key|Shift}}+{{key|ScrLk}}. To fix this, add the following to {{path|~/.Xmodmap}} or {{path|/etc/X11/Xmodmap}} and run <tt>xmodmap</tt> as described before:
keycode 77 = Num_Lock

===Mapping keys with setkeycodes===
You can use the setkeycodes command to remap certain keys. I.e. you can use {{cmdroot|setkeycodes 6e 109 6d 104 69 28 6b 1}} to map the Tablets Up and Down keys to the standard PageUp and PageDown keys and Tablet Escape and Enter to their respective keys.

The following table shows the keycodes generated by the ThinkPad keys.
{| border="1" cellspacing="0" cellpadding="2"
|+ keycodes
! key !! keycode
|-
| {{ibmkey|Tablet orientation|#494949}} || 0x6d
|-
| {{ibmkey|Tablet Shortcut|#494949}} || 0x6e
|-
| {{ibmkey|Tablet Esc|#494949}} || 0x6b
|-
| {{ibmkey|Tablet Enter|#494949}} || 0x69
|-
| {{ibmkey|Tablet Up|#494949}} || 0x68
|-
| {{ibmkey|Tablet Down|#494949}} || 0x6c
|-
| {{ibmkey|Tablet (unlabeled)|#494949}} || 0x67
|}

==Example Applications==
===Web Browsers===
====Firefox====
To have firefox make use of the browser keys you need to modify one of its files{{footnote|3}}.
To do this you will first need to extract it from the {{path|browser.jar}} archive. Do...

:{{cmdroot|cd <firefox-directory>/chrome}} 
:{{cmdroot|unzip browser.jar}}

The file of interest is {{path|content/browser/browser.xul}}. Edit it...
:{{cmdroot|vi content/browser/browser.xul}}

Look for the '''<keyset id="mainKeyset">''' section and add the following lines within...
<key id="goBackKb" keycode="VK_F19" command="Browser:Back" />
<key id="goForwardKb" keycode="VK_F20" command="Browser:Forward" />
Now save the file and repackage the {{path|browser.jar}} archive...
:{{cmdroot|zip -rD0 browser.jar content/browser/}}

That's it.

{{HINT|Another interesting Page on Firefox is http://dqd.com/~mayoff/notes/thinkpad/dqdnavkeys/ It uses different key mappings (F19 resp. F20) but a ready [http://dqd.com/~mayoff/notes/thinkpad/dqdnavkeys/dqdnavkeys-1.2.xpi .xpi] is provided which is pretty comfortable. However, this xpi file does not install on Firefox 1.5.}}

{{HINT|You can also use the [http://extensionroom.mozdev.org/more-info/keyconfig keyconfig] extension to configure custom keys. This extension works with Firefox 1.5.}}

====Konqueror====
KDE allows you set key mappings for KDE applications (Go to KMenu > System > Control Center > Regional & Accessibility > Keyboard Shortcuts). By default (at least in KDE 3.5), XF86Back and XF86Forward are set as alternatives to Alt-Left and Alt-Right, and are mapped to KDE Back and Forward navigation actions.

If you use Konqueror as your only browser, you only need to set up {{path|~/.Xmodmap}} as described [[#xmodmap configuration|above]] to assign ThinkPad back/forward keys to the symbols XF86Back/XF86Forward. This also make these keys work for other KDE applications such as Quanta Plus, KPackage and so on (not all KDE applications honor this setting, e.g. KDE help system doesn't).

If you want to use Firefox, however, the above settings do not work. You will have to map ThinkPad back/forward keys to F19/F20 as described [[#Firefox|above]], and change KDE navigation key settings to use F19/F20 instead of the default.

====Opera====
However this isn't a simple configration file, you can set your browser manually. 
Go to Tool > Settings > Mouse and keyboard > Keyboard settings > Edit > Browser Window. There add F19 - Back and F20 - Forward. Now you can surf using your TP keys ;-)

===Window Managers===
====fvwm====
To get the {{ibmkey|Forward|#494949}} and {{ibmkey|Backward|#494949}} keys to cycle through pages in the virtual desktop, add this to your {{path|~/.fvwmrc}}:
Key XF86Back A A Scroll -100000 0
Key XF86Forward A A Scroll +100000 0
If you use multiple virtual desktops, you could instead use the keys to flip between them by using GotoDesk.

====fluxbox====
To get the keys to cycle through pages in the virtual desktop, add this to your {{path|~/.fluxbox/keys}}:
None F19 :PrevWorkspace
None F20 :NextWorkspace

====pekwm configuration====
You can make the two browser keys switch workspaces in pekwm, by adding the following two lines to the {{path|~/.pekwm/keys}} file:
KeyPress = "Mod1 XF86Back" { Actions = "GoToWorkspace prev" }
KeyPress = "Mod1 XF86Forward" { Actions = "GoToWorkspace next" }

====pwm====
Another example how to use these two keys to switch between pwm tabs. These two lines should be added to {{path|~/.pwm/keys-default.conf}} or {{path|/etc/pwm/keys-default.conf}}:
kbind "Back", "switch_rot", -1
kbind "Forward", "switch_rot", 1

====icewm====
Some applications use {{key|Ctrl}}{{key|Left}} and {{key|Ctrl}}{{key|Right}} to set the cursor to the beginning of the previous / next word. In icewm, though, they're bound to previous / next workspace. Change these two options in {{path|~/.icewm/preferences}} to bind those to {{ibmkey|Forward|#494949}} and {{ibmkey|Backward|#494949}}: (Provided you assigned keysyms F19 and F20 with xmodmap)
# "Previous workspace" shortcut
KeySysWorkspacePrev="F19"
# "Next workspace" shortcut
KeySysWorkspaceNext="F20"

===Other Uses===
====Console tools configuraton====
To make the {{ibmkey|Forward|#494949}} and {{ibmkey|Backward|#494949}} keys useful in console, add this to your keymap ({{path|/etc/console/boottime.kmap.gz}} in {{Debian}}):
keycode 158 = Decr_Console
keycode 159 = Incr_Console

Alternatively you can load this script (perhaps on system startup) to enable Backward/Forward button console (VT) switch:

#!/bin/sh
setkeycodes e06a 126 e069 127
echo keycode 126 = Decr_Console | loadkeys
echo keycode 127 = Incr_Console | loadkeys

It should work with any distro.
