This is an ATI video adapter.


  • Chipset: ATI #rv250
  • PCI ID: 1002:4c66
  • AGP 4X
  • 32, 64, or 128MB DDR-SDRAM video memory
  • External VGA up to: 1680x1050

Linux driver - OpenSource

This adapter is supported by recent versions of the radeon driver as found in X.Org.

OpenGL screen corruption

You may experience screen corruption with Compiz, a workaround for this is to create a file /etc/drirc with the following content

       <device screen="0" driver="r200">
               <application name="Default">
                       <option name="allow_large_textures" value="2" />

ThinkPad LCD

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

External VGA port

Works well, you only have to connect the monitor/projector/...

SVideo port

SVideo out is supported by the ati.2 driver from the GATOS project.
Read here how to set it up.

Linux driver - Proprietary

The fglrx driver adds 3D acceleration. The latest driver version working with this chipset is 8.28.8. ATI has dropped support for this chipset in all further versions.

(It should be noted that to date nobody has been able to get the fglrx drivers to work with the R250 chipset.) <- Incorrect, driver 8.28.8 working on my T41 --Fturner 04:36, 12 April 2007 (CEST)

I have gotten the fglrx drivers working on my Slackware 11.0 T41, kernel 2.6.18. Required adding:

"#define VM_SHM 0xff"

to /lib/modules/fglrx/build_mod/firegl_public.h

I also had to comment out kernel version checking from the file /lib/modules/fglrx/build_mod/ in order to get the module to build. Note that I have no idea what 0xff means, but I do know that 0xffffffff does NOT work.
