Intel Graphics Media Accelerator 950

Intel Graphics Media Accelerator 950 This is an Intel video adapter Features Integrated into the following chipsets: Intel 945GM PCI ID: 8086:???? Uses up to 224MB of main memory for video usage

Linux X.Org driver

Supported by Xorg.

Linux Intel driver

There is a Graphics driver for the Mobile Intel® 945GM Express Chipset Family at Intels Support Site. This driver is just a snapshot of the Xorg/XFree86 driver.

In my case, the i810 driver recommended by multiple sources for this graphics card did not work, leaving a message of "No device found." Running against the generic vesa drivers solves that problem, but does not allow use of the external VGA port.

In Fedora Core 5 at least, the correct i810 driver can be obtained from the updates (in updates-testing as of Aug 15, 2006). With that, the i810 driver seems to work.

ThinkPad LCD

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

External VGA port

Works. Dualhead is supported.

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:

   Section "Device"
       Identifier      "Intel Corporation Mobile Integrated Graphics Controller"
       Driver          "i810"
       BusID           "PCI:0:2:0"
       Option "MonitorLayout" "CRT,LFP"
       Option "DevicePresence" "true" 
       Screen 1
   EndSection
   Section "Device"
       Identifier      "Intel Corporation Mobile Integrated Graphics Controller External CRT"
       Driver          "i810"
       BusID           "PCI:0:2:0"
       Screen 0
   EndSection
   Section "Monitor"
       Identifier      "LCD"
       Option          "DPMS"
   EndSection

   Section "Monitor"
       Identifier      "External CRT"
       Option          "DPMS"
       HorizSync 28-75
       VertRefresh 43-100
   EndSection

   Section "Screen"
       Identifier      "External Screen"
       Device          "Intel Corporation Mobile Integrated Graphics Controller External CRT"
       Monitor         "External CRT"

       SubSection "Display"
               Depth           24
               Modes           "1280x1024"
       EndSubSection
   EndSection

   Section "Screen"
       Identifier      "Default Screen"
       Device          "Intel Corporation Mobile Integrated Graphics Controller"
       Monitor         "LCD"
       DefaultDepth    24
       SubSection "Display"
               Depth           1
               Modes           "1024x768"
       EndSubSection
   EndSection

   Section "ServerLayout"
       Identifier      "Default Layout"
       Screen          0 "Default Screen" 0 0
       Screen          1 "External Screen" RightOf "Default Screen"
       InputDevice     "Generic Keyboard"
       InputDevice     "Configured Mouse"
       InputDevice     "stylus" "SendCoreEvents"
       InputDevice     "cursor" "SendCoreEvents"
       InputDevice     "eraser" "SendCoreEvents"
       InputDevice     "Synaptics Touchpad"
   EndSection

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:

   Section "Device"
        Identifier "Videocard0"
        Driver "i810"
        BusID "PCI:0:2:0"
        Option "MonitorLayout" "NONE,LFP+CRT"
        Option "DevicePresence" "true"
        Option "CheckLid" "false"
        VendorName "Lenovo"
        BoardName "Intel Corporation Mobile Integrated Graphics Controller"
   EndSection

SVideo port

??

DVI port

DVI passthrough is only supported on the T60.

Linux support status is unknown

Suspend behaviour

• Required kernel parameters for suspend to ram: none
• Additional notes:
  • switch to/from X11 to reinitialize display properly (stays black)
  • DO NOT use vbetool to save/restore the video mode, this breakes resume!

ThinkPads this chip may be found in

• T60
• X60, X60s
