=== 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.

 Section "Screen"
    [...]
    SubSection "Display"
       [...]
       Virtual 3072 3072 ## should be enough
    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:

         Driver "intel"
         BusID "PCI:0:2:0"

         Option "CheckLid" "false"

         BoardName "Intel Corporation Mobile Integrated Graphics Controller"

Linux support status is unknown

==== 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.
