Wiki users should link their contributed pages here for others to find. Create new categories as necessary if there isn't an appropriate existing one.


There is a project writing manpages to document the driver-part and the applications of the proprietary ATI driver for the Debian distribution. The manpages can be installed on every system. Because driver options heavily lack documentation, any help is appreciated to complete these manpages. The sources can be found here. Support

  • 6.8, 6.9, 7.0, and 7.1 are supported by the latest fglrx driver.
  • 7.0 page


  • Xgl: A brief rundown on what it brings to the table, plus a How-To on how to get XGL and Beryl up and running on your Ubuntu installation.


DesktopSetup trouble

If you are using the latest (at the time of this writing 8.20.8) drivers with a DesktopSetup and you are wondering why both monitors (eg. the RGB and DVI output) are both displaying the left side of the bigscreen, try the following option (which is AFAIK not documented anywhere, I guessed it):

Option "ForceMonitors" "nocv"

nocv stands for No Composite Video and resulted in a succesful bigscreen setup with my ATI X300 at a debian amd64 unstable system (after many hours). Options like

Option "ForceMonitors" "crt1,tmds1"

And many other combinations of crt1, crt2, tmds1, tmds2 and notv don't seem to have any result!

Power saving features

fglrx driver makes cards hotter and use more power than the radeonhd, vesa or the Windows driver. For description and a workaround please see this blog post.

Video Overlay on AVIVO cards

I've just set up a MythTV box on Ubuntu 8, with a HD 2600 pro graphics card, and my video was very choppy until I noticed the following line in the Xorg.log:

(WW) fglrx(0): Video Overlay not supported on AVIVO based graphics cards. For XVideo support use Option "TexturedVideo".


Option      "TexturedVideo" "true"

to the Device section seems to have fixed it.
