Cz8s:

My Kernel (2.6.30.2) only generates a "change" udev-event. No "dock" or "undock" event.
So I used the ATTR to find out whether docked or undocked.
The udev rules in /etc/udev/rules.d/10-docking.rules look like this now:
ATTR{docked}=="1", KERNEL=="dock.0", SUBSYSTEM=="platform", RUN+="/some/script dock"
ATTR{docked}=="0", KERNEL=="dock.0", SUBSYSTEM=="platform", RUN+="/some/script undock"

=== Intel Extreme Graphics 2 ===
This is an Intel video adapter

=== Features ===
* Integrated in one of the following chipsets:
** [[Intel 855GM]]
** [[Intel 855GME]]
** [[Intel 852GME]]
* PCI ID: 8086:3582
* Uses up to 64MB of main memory
</div>
|style="vertical-align:top" |
|}

=== Linux X.Org driver ===
This chip is supported by the 'i810' driver as part of the X.Org distribution.

Hardware 3-D acceleration is available using DRI and kernel i915 module (2.6 kernel)
for 16-bit depth.

You can configure 3-D acceleration by ensuring that the following is in your xorg.conf:

Section "Device"
Identifier "Intel Corporation 82852/855GM Integrated Graphics Device"
Driver "i810"
BusID "PCI:0:2:0"
Option "DRI" "true"
EndSection

To check that it's working, run glxinfo | grep direct and check that direct draw reports as "Yes"

There are binary drivers for SuSE and a modified X.Org distribution available from Intel.

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

==== External VGA port ====

===== X.org =====

======Clone======
At least using X.org 6.9.0, the following will always enable the VGA port:

Section "Device"
Identifier "VideoCard0"
Driver "i810"
Option "VBERestore" "yes"
Option "Clone" "true"
Option "MonitorLayout" "CRT,LFP"
Option "DevicePresence" "yes"
EndSection

To change to which pipe the overlay is directed (e.g. when playing a movie in xine), use:

xvattr -a XV_PIPE -v ''DISPLAY''

Where ''DISPLAY'' is either 0 (with the above setup, the CRT) or 1 (with the above setup, the Local Flat Panal).

======MergedFB======

With MergedFB you can use an external Display with another resolution.
To enable MergedFB, you need to edit your Screen-Section and your Device-Section.

In the Screen-Section, you need to add a Resolution for all resolutions. Your Laptop-Display and your External Display.

And you have to add a "virtual" Resolution which is the biggest resolution of both. Like this:

Section "Screen"
Identifier "Default Screen"
Device "Intel Corporation Mobile Integrated Graphics Controller"
Monitor "Generic Monitor"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1024x768 1280x768"
Virtual 1280 1024
EndSubSection
EndSection

In your Device-Section of the Card, you need to add some Tags. MetaModes consits of every Resolution you need to use.
This looks like this.
Section "Device"
Identifier "Intel Corporation Mobile Integrated Graphics Controller"
Driver "i810"
BusID "PCI:0:2:0"
Option "DevicePresence" "true"
Option "DRI" "true"
Option "MergedFB" "true"
Option "MergedXinerama" "false"
Option "MonitorLayout" "CRT,LFP"
Option "MetaModes" "1280x1024-1024x768 1024x768-1024x768"
EndSection

I had to set the MergedXinerama to false because it reported a Screensize of 0,0,-1,-1 which makes the Windowmanager behave funny.
But with this setup it is possible to use RandR to switch from the Resolution of your Laptop-Display to the Resolution
of your bigger external Display without quitting your X-Session. Your Laptop-Display will then scroll to show the part of your
Desktop where your mouse is.

===== i855crt =====

There seems to be many issues trying to do this from within {{path|/etc/X11/xorg.conf}} or {{path|/etc/X11/XFree86.conf}}. The solution for basic projector or cloned output is to use the [http://i855crt.sourceforge.net/ i855-crt] program. Remember that this program is very raw and could damage your display equipment.

Once this is installed an example command would be (with root permissions):
:{{cmdroot|i855crt swcursor on "1024x786@85"}}
to stop it enter
:{{cmdroot|i855crt off}}

The video mode in quotes is defined in {{path|/etc/i855crt.conf}} or {{path|~/.i855crt.conf}}.
{{Fixme|This is specific usage information for that tool. Introducing an own tool page for it should be considered or joining this with other information in a display cloning howto page.}}

Using MonitorLayout and Clone options it is possible to setup cloned display with X.Org (tested with 6.9.0). Dualhead supported by Xorg driver.

==== SVideo port ====
?

==== DVI port ====
DVI Pass-through to a Dock or Port Replicator is not supported on any ThinkPad with this chipset.

=== Linux kernel Framebuffer driver ===
This chip will work with either the 'vesa' or 'intelfb' driver as part of any recent 2.4 or 2.6 kernel.
