|
Linux X.Org driver
This adapter is supported by recent versions of the 'ati' driver as found in X.Org.
ThinkPad LCD
Display on the internal LCD works as long as you set the monitor settings correct.
External VGA port
The external VGA port can be enabled in /etc/X11/xorg.conf via
Option "crt_display" "On"
Dualhead seems not to be supported, yet.
Accelerated Graphics
4MB is not sufficient RAM for 3D-acceleration at 16 bit colour. 8 bit colour is too unpleasant to contemplate (and it doesn't work very well anyway). So, most X20s don't (effectively) have 3D. However, 24-bit colour is possible without 3d.
SVideo port
SVideo out is supported by the ati.2 driver from the GATOS project.
Read here how to set it up.
Proprietary ATI driver
This chip is not supported by the proprietary ATI driver.
Linux kernel Framebuffer driver
A framebuffer driver is in recent kernels (2.6.15), marked as experimental. A test on a X20 was yet unsuccessful though.
