Intel Graphics Media Accelerator X3100

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 [1]. 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 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.

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.
