==Windows XP port==
How would I port this patch to Windows XP?

--Jason

You can't. But you can write a Windows device driver based on the specs and [[ibm-acpi]].

==gkrellm support==

I can confirm that it works on Thinkpad {{T43}} here. However after
applying the patch, the fan speed monitor of gkrellm 2.2.7 cannot read
value correctly. Maybe we gkrellm is reading the second line for speed
but instead find the line for level, so it got confused? Would it be possible to interchange the lines so that speed still appears in the
second line and level appears in the third instead? I'm no coder, just
a suggestion to improve the patch.

--Jiang

I'd say it's a bug in gkrellm. It should parse the line header rather than relying on line numbers. But feel free to change (and test) the patch if you wish.

== patch to keep gkrell working against 2.6.14 ==

As in "works for me on a T43p", use with caution at your own risk. And thanks to thinker for the original patch, very nice work.

(See article for the actual patch)

--[[User:Spiney|Spiney]]

Looks excellent, why not add it to the article page? Also, care to provide a license (preferably public domain like my patch) so the kernel guys can handle it? Speaking of which, the kernel people seem to like their patches generated via "diff -up vanilla-kernel-2.6.14 patched-kernel-2.6.14".

--[[User:Thinker|Thinker]] 22:04, 1 Nov 2005 (CET)

Done, using the -p option for diff and "borrowing" your sentence for licensing purposes.

== Updated script for unpatched kernels ==
Moved to the [[ACPI fan control script]] article page, after joint development by [[User:Spiney|Spiney]] and [[User:Thinker|Thinker]].

== whats the problem kernel 2.6.14 ==

hi all,

i patched the kernel with the patch for 2.6.14 with the option:
/usr/src/linux # patch -p0 -l -i ../ibm_acpi.patch (which i copy&pasted)

they dont show me errors or so. but after i reboot and load the modul ibm_acpi i cant see any /proc/acpi/ibm/fan

whats the problem? copy&past ( tab -> space?)
or is it a problem in my kernel config?

greetings and big thx from .ch,

system: ibm thinkpad t43p
kernel: 2.6.14

--[[User:62.203.29.204|62.203.29.204]] 19:22, 9 Nov 2005 (CET)kru

You need to pass the "<tt>experimental=1</tt>" module parameter to ibm-acpi:
# modprobe ibm_acpi experimental=1
--[[User:Thinker|Thinker]] 21:01, 9 Nov 2005 (CET)

big thx!!! problem solved.

== Fan control does not work with Suse 10.1 ? ==

Hi,

I successfully installed and used the fan control script on my T43p with Suse 10.0.

Yesterday, I installed Suse 10.1 from scratch. Unfortunately fan control does not work with Suse 10.1:

\# echo level 2 > /proc/acpi/ibm/fan
bash: echo: write error: Invalid argument

Are there any substantial differences between Suse 10.0 and 10.1 with respect to ibm_acpi?

== Speed Control Patch for 2.6.18? ==

Hi All.
I'm trying to apply the speed control patch to vanilla 2.6.18 but it looks like it failed. Anyone who can point me to a direction for 2.6.18 patch?
Thanks

== ibm-acpi-0.12a-2.6.17-fan.patch broken? ==
The code is not completed.

Problems with fglrx

2006-05-30T02:02:51Z

Bitcalc:

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 8.24.8).

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' (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 expierence 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 agp driver. Make sure that you have proper driver for your motherboard loaded before fglrx: (gentoo: {{path|/etc/modules.autoload.d/kernel-2.6}}):
intel-agp
fglrx

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

===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

Ahh - thanks for the info. You perhaps compiled the modules for the drivers yourself and did not use the debian packaged fglrx-driver? Thus, it must be an unneeded limitation on the debian packaged driver which limits its installation... Full listing at http://packages.debian.org/unstable/x11/fglrx-driver which lists as required packages:

xserver-xorg (<< 6.8.99)
the X.Org X server
xserver-xorg (>= 6.8.0)

The first limitation (<<6.8.99) is what prevents installation. I'm sure I could force apt to install it, but I may go back to compiling the modules myself, as using fglrx 8.20.8 with kernel 2.6.15 needs a small patch to compile correctly anyway... --[[User:gsmenden|gsmenden]]

Spiney, where exactly do you have your package from? I re-build the 8.20.8-package from debian with the <<6.8.99 dependecy removed, but when I try to run X, I get
[R200Setup] X version mismatch - detected X.org 7.0.0.0, required X.org 6.8.0.0
(EE) Failed to load module "fglrx" (module requirement mismatch, 0)
Any hints? --[User:nomeata|nomeata]

I used the ati-installer (the huge download), created a Debian sid package and installed it, but got the same error. The installer seems to fetch the wrong driver version from the archive, so I extracted it with

{{cmd|./ati-driver-installer-8.20.8-i386.run --extract <sometempdir>|}}

and put the necessary files from the created {{path|<sometempdir>/x690}} subdirectory into {{path|/usr}} by hand. All IIRC, it's been some time since. :)

--[[User:Spiney|spiney]] 07:29, 11 Jan 2006 (CET)

Thanks for the pointer. This is how you get proper debian packages out of the ati-installer:
./ati-driver-installer-8.20.8-i386.run --extract fglrx-tmp
cd fglrx-tmp
$editor packages/Debian/ati-packager.sh # in the line "sid|unstable) X_DIR=x680;;", put a x690 for the x680
./fglrx-tmp/packages/Debian/ati-packager.sh --buildpkg sid
cd ..
sudo dpkg -i fglrx-kernel-src_8.20.8-1_i386.deb fglrx-driver_8.20.8-1_i386.deb
--[[User:Nomeata|Nomeata]] 00:35, 13 Jan 2006 (CET)

I had to do following steps :

$ ./ati-driver-installer-8.20.8-i386.run --extract fglrx-tmp
$ cd fglrx-tmp
$ ''editor'' packages/Debian/ati-packager.sh # in the line "sid|unstable) X_DIR=x680;;", put a x690 for the x680
$ ./packages/Debian/ati-packager.sh --buildpkg sid
$ cd /tmp
$ sudo dpkg -i fglrx-kernel-src_8.20.8-1_i386.deb fglrx-driver_8.20.8-1_i386.deb
--[[User:Fbianco|Fbianco]] 13:36, 26 February 2006 (CET)

----

Nice - confirmed works on my T43p running sid. From then on (or until 8.21.x comes out) you'll have to tell apt to hold back fglrx-driver package, or it will try to "update" fglrx-driver to 8.20.8-1.1 and therefore revert back to the problematic drivers.
--[[User:gsmenden|gsmenden]]

Thanks for the info, Nomeata, that's a lot cleaner a solution than my manual way.

--[[User:Spiney|spiney]] 08:32, 13 Jan 2006 (CET)

To get this working under 2.6.15 with x.org 6.9, you will also need to apply a small patch - there is a link on the main article page. After you install the fglrx-driver package with the 6.9 versioning hack above, go to
/usr/src/modules
and copy the patch here. Modify the first two lines of the patch file to take out the "build_mod" directory, e.g. first line should begin with
--- fglrx.orig/firegl_public.c
and call it with the -p0 strip option. It should patch the firegl_public.c file cleanly. You can then install as usual for your kernel (2.6.14.x or 2.6.15) using module-assistant.

Update - although X will come up in kernel 2.6.15 with the fglrx drivers patched as above, there is some strange behavior exhibited in all of X apllications - frequent hanging of applications when closing windows. Reverting back to the radeon driver in 2.6.15 solves these - so it is likely the ATI proprietary driver causing some problems.

Yet another update - fglrx 8.21.7 is out as of 1/19/2006, now supporting OpenGL 2.0, so eventually we will have beautiful complex shading / fog effects on Linux, too. It works well with X.Org 6.9 out of the box.

Unfortunately, this version gives the same problems when used (unpatched) with kernel 2.6.15 with strange lockups occasionally requiring reset of X. I have not tried this with the ~10 line patch listed on the main site, but that patch not work for me with 8.20.8. Anybody else have experience with 2.6.15 and fglrx?

Yay - new version out - 8.22.5 - works well with 2.6.15.x. Finally, running a plain-vanilla kernel on a T43p! (SATA+libata passthrough+SMART in mainline, 3d accel drivers up to date. Linux life is good.)

I don't know which patch you mean exactly (10 lines? the patch from lkml is just one line changed, no?), but I've been using 8.20.8 with 2.6.15 for quite some time (actually started with some -rc version IIRC), no lockups at all. No idea about 8.21.7 though, because I switched to 2.6.16-rc1 and can't compile the fglrx module at the moment, need to investigate the cause.

--[[User:Spiney|spiney]] 07:24, 21 January 2006 (CET)

Ok - strange. Yeah, the actual change is only one line, the rest is just commenting, etc. The lockups that I get are quite rare, but flightgear occasionally gives a hard lock. glxgears and fgl_glxgears work fine, netscape occasionally will hard-lock, and strangely enough issuing a shutdown command often makes the display blank and hard lock. I can't reproduce them too consistently, but these _never_ occur with the radeon driver / mesa or under 2.6.14.x.

Unfortunately vanilla 8.21.7 with kernel 2.6.15.1 (Xorg 6.9) gives the same X lockups.

I can't compile the 8.21.7 driver modules with 2.6.15.1 at all. They compile with 2.6.14.4 cleanly and 8.20.8 compile with 2.6.15.1.
What I don't understand though is, that when I let the ATI installer build debian packages, it does so without hassle, but the packages don't work.
(this is about 8.21.7 - 2.6.15.1) Also patching doesn't seem to help. It shouldn't of course.

--[[User:Rasto|Rasto]] 15:04, 23 Jan 2006 (CET)

I looked at the compile problems last night. I have no idea, how it is possible that it works for other people with 2.6.15, perhaps when you install
precompiled modules? I don't really understand how that ati-installer thing works. Anyway. This may solve the problems with 8.21.7 and 2.6.15-
it is just two minor line changes (+ the one line patch with little extra), but now it compiles. pm_register and similar were moved to linux/pm_legacy.h
in 2.6.15, so that's one problem. It also reports unknown symbol verify_area, but this should not pose a problem, as it is already obsolete and redundant.
If you feel, that the one line should be left as the separate patch, copy it somewhere else and change it. It's here [http://people.ksp.sk/~rasto/fglrx_with_2.6.15.patch], but I'll put it on the main page as well.

== Disabling the external VGA port? ==

Does anyone know how disable the VGA port ''completely'' even when a cable is attached? Fiddling around with the DesktopSetup and ForceMonitor options didn't do the trick for me, and the MonitorLayout option found in some documentation is no longer valid in the current fglrx driver.

== On Kernel 2.6.16(_rc4-mm1) fglrx doesnÂ´t load anymore ==

Hi,

if i emerge ati-drivers 8.22.5 and try to modprobe it on Kernel 2.6.16_rc4-mm1 i get the following console output:
<pre>
FATAL: Error inserting fglrx (/lib/modules/2.6.16-rc4-mm1/video/fglrx.ko): Unknown symbol in module, or unknown parameter (see dmesg)
</pre>
my dmesg Output reads:
<pre>
fglrx: Unknown symbol inter_module_unregister
fglrx: Unknown symbol inter_module_get_request
fglrx: Unknown symbol inter_module_put
fglrx: Unknown symbol inter_module_register
</pre>
from the ati-driver wiki i know that the driver runs on 2.6.16 up to rc3. But on the mm Series it doesnt run since 2.6.15.4-mm4.

Help would be appreciated...

Thanks and Greets

Oli

I have a t43p / Debian Sid running 2.6.16 debian kernel compile the debian way. And the fglrx modules compiled.
There are two problems that I can not seem to fix...
o If I log out of kde to kdm/ or the login, everything goes black, even Alt+Ctrl+F1 does not work. It is not locked up as Ctrl+Alt+Del does a proper restart.
o The other problem is on the second monitor the screen boundary is not right. Putting the mouse to the bottom cause a vertical blur. As long as the mouse is not at the bottom of the second screen all is well.

Did you tell KDM to restart the X server when logging out? It is described in a link on the main article page under "Hang when logging out." I don't have two monitors so I'm not sure about your other problem...

==Emacs with GUI affected==
I installed fglrx 8.20.8 on SuSE 10.0 with kernel 2.6.13 on T43 and fglrx 8.24.8 on Ubuntu 5.10 with kernel 2.6.12 on T40. On both systems, emacs works well with "-nw" option. However, in the first system, emacs doesn't respond to any key stroke when started with GUI interface, but it works well with "emacs -font fixed". In the second system, Emacs displays all characters as empty rectangles and responds to all key strokes althouth they are illegible. If I use the xorg.conf before fglrx was installed, then emacs works perfectly. I doubt that the problem is caused by the font. But it stays there even if I use the same fontpaths under section "Files".

Does anyone else have this problem? I haven't found any other X applications affected by the use of the driver.

Problems with fglrx

2006-05-28T06:04:35Z

Bitcalc: /* Emacs with GUI affected */

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 8.24.8).

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' (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 expierence 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 agp driver. Make sure that you have proper driver for your motherboard loaded before fglrx: (gentoo: {{path|/etc/modules.autoload.d/kernel-2.6}}):
intel-agp
fglrx

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

===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

== Other Known Problems ==

===Emacs with GUI affected===
I installed fglrx 8.20.8 on SuSE 10.0 with kernel 2.6.13 on T43 and fglrx 8.24.8 on Ubuntu 5.10 with kernel 2.6.12 on T40. On both systems, emacs works well with "-nw" option. However, in the first system, emacs doesn't respond to any key stroke when started with GUI interface, but it works well with "emacs -font fixed". In the second system, Emacs displays all characters as empty rectangles and responds to all key strokes althouth they are illegible. If I use the xorg.conf before fglrx was installed, then emacs works perfectly. I doubt that the problem is caused by the font. But it stays there even if I use the same fontpaths under section "Files".

Does anyone else have this problem? I haven't found any other X applications affected by the use of the driver.

Problems with fglrx

2006-05-28T06:03:50Z

Bitcalc: emacs

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 8.24.8).

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' (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 expierence 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 agp driver. Make sure that you have proper driver for your motherboard loaded before fglrx: (gentoo: {{path|/etc/modules.autoload.d/kernel-2.6}}):
intel-agp
fglrx

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

===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
