=== Linux X.Org driver ===
Supported by Xorg [http://www.x.org/wiki/IntelGraphicsDriver?highlight=%28intel%29%7C%28driver%29]. The driver supports hardware accelerated 3D via the Direct Rendering Infrastructure (DRI), but only in depths 16 and 24.

Version 2.1.1 of the driver fixes a TV output problem. Use xrandr to view the enabled screens in X.

=== Linux Intel driver ===
There is a Graphics driver for the Mobile Intel 965 Express Chipset Family at [http://downloadfinder.intel.com/scripts-df-external/filter_results.aspx?strTypes=all&ProductID=2301&OSFullName=Linux*&lang=eng&strOSs=39&submit=Go%21 Intels Support Site]. This driver is just a snapshot of the Xorg/XFree86 driver.

==== ThinkPad LCD ====
Display on the internal LCD works as long as you set the monitor settings correct.

==== External VGA port ====
Works. Dualhead is supported.

===== Dynamic configuration: XRandR =====
Since xorg>=7.3 and 2.2 intel driver, XRandR 1.2 works for adding/removing monitors on the fly. The only hard-coded thing is virtual desktop size in xorg.conf, which must always encompass all monitors and may not be changed at X runtime.

For the rest, see man xrandr, I have a script to turn on dual-head at work (self-explanatory):

xrandr --newmode "1440x900" 106.5 1440 1520 1672 1904 900 901 904 932 -HSync +VSync
xrandr --addmode VGA 1440x900
xrandr --output VGA --mode 1440x900
xrandr --output VGA --right-of LVDS

To disable external (VGA) screen,

xrands --output VGA --off

===== Static configuration via /etc/X11/xorg.conf =====

There are two options for running the external VGA port - either as a copy of the LCD (clone) or as a separate workspace. Here is an example for the separate workspace mode for xorg.conf for the X60s:
Be warned that making the following changes to xorg.conf
on an X61 with the Intel 465 chipset
kills x and must be removed to regain a graphical display.

Problem with display remaining black after resume

2007-11-09T12:50:07Z

Eudoxos: /* Affected Models */

There has been a problem encountered where the display stays black on resuming from suspend.

The symptom might have you think first that your system hang up, but you will realize that your ThinkPad works and you can even reset it via {{key|Ctrl}}{{key|Alt}}{{key|Del}}.

==Affected Models==
*ThinkPad {{T41p}}, {{T42}}, {{T42p}}, {{T43}}, {{T43p}}, {{T60}}, {{T60p}}
*Thinkpad {{T23}}
*ThinkPad {{X21}}, {{X30}}, {{X31}}, {{X40}}, {{X41}}
*ThinkPad {{R31}}, {{R50e}}{{footnote|1}}, {{R50p}}, {{R51}} (with BIOS 1.11), {{R52}}, {{R60}}, {{R61}}
*ThinkPad {{A30p}}
*ThinkPad {{390X}} (doesn't wake up; LCD backlight on, harddrive light remains on)
*ThinkPad {{Z60t}}, {{Z60m}}, {{Z61m}}, {{Z61e}}
*ThinkPad {{X60s}}, {{X60}}, {{X61s}}

==Affected Operating Systems==
*Linux (it's a kernel issue)
*FreeBSD (6.x at least)

==Solutions==
===Quick workaround for R61i, T23, maybe others===
Try pressing CTRL+ALT+F1 to switch to text console. The backlight should come on normally. Press CTRL+ALT+F7 to return to X.

On a T23 pressing Fn+F7 (external/internal display change) once or twice brought the display back on Ubuntu Feisty. After upgrading to Ubuntu Gutsy it doesn't work, but pressing Fn+F3 (blank screen) and Fn+F7 (or some sequence of them) works.

=== Solution for ThinkPad Z60t ===

* '''Display controller:''' Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03)
* '''Distro:''' Fedora release 7 (Moonshine)
* '''Kernel:''' Linux 2.6.22.5-76.fc7

The solution is straight forward - just to add configuration parameter for the default '''pm-utils''' package. Create file <code>/etc/pm/config.d/config</code> and put there one line <code>DISPLAY_QUIRK_S3_BIOS="true"</code>, or execute following command:

echo DISPLAY_QUIRK_S3_BIOS=\"true\" >> /etc/pm/config.d/config

===Semi-Solution for ThinkPad X60 with damaged system after s2ram usage===
It happend when restarting a s2ram-session.

'''Symptom:''' Black screen with blinking "_" sign remaind. (without the ")

'''System status:''' HDD idle, fan running, everything else looks to wait for something to happen.

'''Semi-Solution:''' Booting with DVD-ROM and going through the installations menu,
where you choose "other" and "boot a installed system" (something like that). Gladly it works,
and OpenSuSE 10.1 comes up with 50% "failed" messages! I than shutdown properly, rebooted again
and had 100% "done" again, with no other things affected.

'''Further:''' Repairing with the DVD-ROM crashed massivly(!), so I selected "boot a installed system" as final
solution and it worked!

'''Unknown:''' Maybe the Solution for ThinkPads with 1400x1050 internal LCD and Intel 915GM will help,
because X60s and X60 are very familiar. (Not tested so far.)

(If this Problem is not right here, please edit and move.)

===Solution for ThinkPads with 1400x1050 internal LCD and Intel 915GM ===
see [[1400x1050 on Intel 915GM]].
===Solution for ThinkPads with ATI graphic chips and Intel 915/945GM ===

Affected models include {{X60s}}, {{R60}} and {{T60}}.

This soluton also applies to T42 with Intel 855 and ATI 9600 M10.

One solution may be to provide the {{bootparm|acpi_sleep|s3_bios}} kernel parameter in your kernel parameter line.

For grub this would look like this:

title Linux, kernel 2.6.11-1-686
root (hd0,0)
kernel /boot/vmlinuz-2.6.11-1-686 root=/dev/hda1 ro acpi_sleep=s3_bios
initrd /boot/initrd.img-2.6.11-1-686
savedefault
boot

For lilo it would look like this:

image=/boot/vmlinuz
append="acpi_sleep=s3_bios"

The actual process of going to sleep is then managed through a sleep script; as a start, see the {{path|sleep.sh}} script in the Extreme Graphics 2 section below, but note the following comments:

In [[:Category:OpenSUSE|OpenSUSE]] 10.1 (at least on a T43p), it's necessary to override the default options for s2ram if you're using the newer ATI driver. This can be done putting {{bootparm|SUSPEND2RAM_FORCE|"yes"}} and {{bootparm|SUSPEND2RAM_ACPI_SLEEP|"3"}} in {{path|/etc/powersave/sleep}}.

In {{Ubuntu}} or {{Kubuntu}}, it may be necessary to modify {{path|/etc/default/acpi-support}}. In that file, make sure that {{path|ACPI_SLEEP}} is uncommented and set to true. With ATI chips, also make sure that {{path|SAVE_VBE_STATE}} is uncommented and set to true; with Intel chips, on the other hand, ensure that nothing is done with respect to VBE--no reposts, no state saves. Also commenting POST_VIDEO may help.

In {{Fedora}}, it may be necessary with the Intel chips to edit the {{path|resume_video()}} function in {{path|/etc/pm/functions-intel}} to comment out the VBE post and restore. (As of FC6 these seem to be pre-commented out.) Also, the laptop, after waking up, may go back to sleep immediately or whenever the AC adapter is disconnected. When this happens, it's caused by a bug in the HAL daemon that incorrectly reports certain ACPI events. This is a known problem and a simple workaround is described [http://live.gnome.org/GnomePowerManager/Faq#head-b8b1280115b0a51c2cc27b13a57121130ebf36cb here].

{{NOTE|It is possible this method will not work if the laptop is docked. It is also possible that the cited workaround for the HAL daemon bug will not work on some machines. A kludgier workaround in this event is to kill the HAL daemon on suspend. This necessitates the resuscitation of GPM upon resume.}}

Another solution is to use vbetool. If you are using {{Debian}} with the hibernate package, uncomment "EnableVbetool yes" in {{path|/etc/hibernate/hibernate.conf}} (or {{path|/etc/hibernate/ram.conf}}).

----

On '''T60 2007-CTO''' (Core2Duo 2Ghz, 2GB Ram, ATI X1400) the screen stayed blank after suspend-to-ram until I set '''vga=0''' in lilo.conf.

Working config:
Linux 2.6.21.5
fglrx 8.37.6
debian etch:
powersaved 0.14.0-5:
UNLOAD_MODULES_BEFORE_SUSPEND2DISK="usb_storage ohci_hcd uhci_hcd ehci_hcd ipw3945 pcmcia yenta_socket rsrc_nonstatic pcmcia_core"
UNLOAD_MODULES_BEFORE_SUSPEND2RAM="usb_storage ohci_hcd uhci_hcd ehci_hcd ipw3945 pcmcia yenta_socket rsrc_nonstatic pcmcia_core"
hibernate:
SwitchToTextMode yes
lilo.conf:
vga=0

"EnableVbetool yes" and other suggestions didn't work for me.

For suspend-to-disk, don't load fglrx in initrd.

----

===Solution for ThinkPads with Intel Extreme Graphics 2===
{{NOTE|
On [[:Category:X40|X40]]s/[[:Category:X41|X41]]s - even with Intel Extreme Graphics - and for [[:Category:R52|R52]]s with Intel Graphics Media Accelerator 900 the [[Problem with display remaining black after resume#Solution for ThinkPads with ATI graphic chips|solution for ATI graphics chips]] above is reported to work. In this case, make sure no changes to VBE are made, especially no state saves and no reposts.}}

The following solution should work on 865G, 865GV, 855GM, 855GME, 852GME chipsets.
*First of all, '''do not''' use the {{bootparm|acpi_sleep|s3_bios}} kernel parameter.
*Second, completely remove framebuffer support from your kernel. If it's built as modules, it is important that they do not get loaded at all.
*Before suspending, change to a console and safe the video state with {{cmdroot|cat /proc/bus/pci/00/02.0 > /tmp/video_state}}.
*On resume, restore the video state with {{cmdroot|cat /tmp/video_state > /proc/bus/pci/00/02.0}} and change back to X.
*For Debian Etch 4.0 on R50e just make following changes to /etc/default/acpi-support:
#SAVE_VBE_STATE=true
#VBESTATE=/var/lib/acpi-support/vbestate
#POST_VIDEO=true
SAVE_VIDEO_PCI_STATE=true

*For a R50e the only thing needed to make suspend to ram work in Ubuntu 6.06 is adding
Option "VBERestore" "yes"
to the <tt>Device</tt> section in your {{path|/etc/X11/xorg.conf}}, and the example script below.

The following example {{path|/etc/acpi/actions/sleep.sh}} script shows how to integrate the according lines.

#!/bin/bash

# change to console 1
FGCONSOLE=`fgconsole`
chvt 6

# safe video state
cat /proc/bus/pci/00/02.0 > /tmp/video_state

# sync filesystem
sync

# sync hardware clock with system time
hwclock --systohc

# go to sleep
echo -n 3 > /proc/acpi/sleep

# waking up
# restore system clock
hwclock --hctosys

# restore video state
cat /tmp/video_state > /proc/bus/pci/00/02.0

# change back to X
chvt $FGCONSOLE

# clean up behind us
rm /tmp/video_state

With Ubuntu 6.10 on a [[:Category:R51|R51 (2887-32G)]] I ''just'' (as none of the other tricks above) had to add {{bootparm|fb|false}} to the kernel line in {{path|/etc/grub/menu.lst}} and edit {{path|/etc/defaults/acpi-support}} this way:

SAVE_VBE_STATE=false
POST_VIDEO=false
SAVE_VIDEO_PCI_STATE=true
USE_DPMS=false
DOUBLE_CONSOLE_SWITCH=false

===Solution for ThinkPads with Intel I830 Chipset===
The following solution worked for me on an X30 with I830M chipset with kernel >= 2.6.16.
*this works with vesafb and also with intelfb frambuffer support.
The following example {{path|/etc/acpi/actions/sleep.sh}} script shows how to integrate the according lines.

#!/bin/bash

FGCONSOLE=`fgconsole`
chvt 8
sync
hwclock --systohc

echo -n "mem" > /sys/power/state

hwclock --hctosys
vbetool post

if [ "$FGCONSOLE" -ge "7" ] ; then
chvt $FGCONSOLE
else
chvt 7
chvt $FGCONSOLE
fi
===Solution for ThinkPads with ATI graphic (and possibly other) chips and FreeBSD===

The FreeBSD acpi(4) manpage mentions a tunable parameter, "hw.acpi.reset_video":

hw.acpi.reset_video
Reset the video adapter from real mode during the resume path.
Some systems need this help, others have display problems if it
is enabled. Default is 0 (disabled).

This tunable can be set by adding the following line to your FreeBSD machine's /boot/loader.conf file:

hw.acpi.reset_video="1"

And rebooting your machine. Hopefully, the next time you resume from a suspend, you'll see your video again. This solution doesn't appear to be specific to ATI hardware in any way, so I presume it would be helpful for video chipsets other than ATI, as well.

If this entry doesn't help you, you might consider searching in the [http://lists.freebsd.org/pipermail/freebsd-mobile/ FreeBSD-Mobile email-list archive] for more insight.

#If you have this problem with R50e and the above solution doesn't work, try switching to console first. An example sleep script can be found [[How to configure acpid|here]].

===Solution using s2ram for Intel 915/945GM===

Just using the "s2ram -f -p" command from the uswsusp package will work from within X, at least on a {{Z61e}}. On {{X60s}} it is enough to issue the "s2ram" command and it works.
