=== Intel Graphics Media Accelerator X3100 ===
This is an Intel video adapter

=== Features ===
* Integrated into the following chipsets:
** [[Intel 965]]
* PCI ID: 8086:2A02
* Uses part of main memory for video usage

=== 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.

SubSection "Display"
[...]
Virtual 2048 2048 ## maximum for Compiz Fusion to work. If you don't need it then 3072 3072 or higher recommended.
EndSubSection
EndSection

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.

Here is the relevant text for running the VGA port as a true clone (so even things like Xine video playback appears on both screens) of the internal LCD display:

==== SVideo port ====

Does not work with Ubuntu 7.10.
See https://bugs.launchpad.net/ubuntu/+bug/178910

==== DVI port ====

The DVI port on a [[ThinkPad Advanced Mini Dock]] is supported and works with dual-head. Follow the notes for the VGA output above, but replace "VGA" with "TMDS-1".

There is almost certainly a way to make the xrandr commands run automatically when you dock or undock. I'll figure it out once I [[Installing_Ubuntu_8.04_(Hardy_Heron)_on_a_ThinkPad_T61|install Hardy]] (I just tried it with the beta Live CD).

==== Suspend behaviour ====
* Required kernel parameters for suspend to ram: none
Nevertheless, you may get a blank screen on resume (for example on T61 with Ubuntu Gutsy). See [https://bugs.launchpad.net/ubuntu/+bug/134391 launchpad bug] for details.

==== Compiz won't work with external Monitor ====
As told here [https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/146298 Link] in Ubuntu 8.10 there is a bug in the MESA driver, that prevents you from using resolutions bigger then 2048x2048. If you connect a second monitor bigger then 1024 compiz (and DRI) won't work.

You can check your system with the command

ajonat@daphne:~$ glxinfo -l | grep GL_MAX_TEXTURE_SIZE
GL_MAX_TEXTURE_SIZE = 2048

The number (here 2048) is the resolution limit.

You have to compile the intel x-server (only on ubuntu 8.04) and the mesa driver. [http://ebsteblog.wordpress.com/2008/08/27/dual-head-on-ubuntu-hardy-with-intel-gm965-part-1/ here] is the whole procedure described.

If you're using Ubuntu 8.10 you can also use the precompiled deb file [http://www.mediafire.com/?jwt2zxmx5x1 here]
