Intel Graphics Media Accelerator 900

This is an Intel video adapter

Features

Integrated into the following chipsets:
- Intel 910GML
- Intel 915GM
PCI ID: 8086:2592
Uses up to 128MB of main memory

Linux X.Org driver

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

For DRI-Support, you may have to install the latest Drivers from DRI Snapshot you need following files:
common-<CurrentVersion>-linux.i386.tar.bz2
i915-<CurrentVersion>-linux.tar.bz2
Extract both in the same Directory and run install.sh
After that restart your X-Server and enjoy OpenGL-Support ;-)

At least on a T43, you also want to add acpi_sleep=s3_bios to the kernel command line (edit your LILO or GRUB configuration file to do that), in order to make sure that Xorg continues to work after a suspend/resume cycle.

Linux Intel driver

You can find Linux drivers for this card on Intel's site. The site offers much information about how to install this card on many distributions, mainly Red Hat and SuSe. The "Intel" driver above 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 well in clone mode at least. Dualhead is supported.

/etc/X11/xorg.conf

       Section "Device"
           Identifier      "Intel Corporation Intel Default Card"
           Driver          "i810"
           BusID           "PCI:0:2:0"
           Option          "MonitorLayout" "CRT,LFP"
           Option          "Clone" "true"
       EndSection

Now you can enable|disable vga out with i810switch crt on|off

SVideo port

See above, but use

       Option          "MonitorLayout" "TV,LFP"

Now you can turn on/off the TV-Out by executing the commands

# echo "dvi_enable" > /proc/acpi/ibm/video

or

# echo "dvi_disable" > /proc/acpi/ibm/video

Or toggle between them with

# echo "video_switch" > /proc/acpi/ibm/video

This is known to work on a T43.

Hint:

Of course you can also use all 3, that makes "TV,LFP,CRT" (in that order).

DVI port

DVI could theoretically be supported if a TMDS transmitter where hooked up to one of the pipes, which is NOT the case on any ThinkPad.

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.
