After recently upgrading my xorg libraries to the ones in "unstable" (on a mostly "testing" system), I lost both xvideo and 3D support. That is, xvinfo shows the message "no adaptors present", while playing a simple 3D game such as ppracer shows abysmal frame rates of 3FPS. What did I do wrong? Is there some new library dependency that needs to be installed?
Some info about my system: linux 2.6.29-1-amd64, xserver-xorg-video-radeon 6.12.2-1, libdrm2 2.4.9-1, and lib*-mesa-* 7.4-2.
The actual use of the radeon driver is confirmed via grep /var/log/Xorg.0.log, that shows among other things:
(II) LoadModule: "radeon"
Perhaps the most puzzling aspect of my problem is the disappearance of xvideo support. If ever, this is the first time (counting back from the days of XFree86) that I have an X Window setup where the xvideo extension fails to work when using the *correct* free driver (both nv and radeon). So this may be a clue to what is wrong with my system.
Sorry, I thought it was obvious (it's my user name): I'm using the on-board video of my AMD690 [correction: not AMD780G] motherboard, an ATI Technologies Inc RS690 [Radeon X1200 Series]. Hardware accelerated 2D and 3D were working when I (temporarily) had some Ubuntu (!) mesa packages installed (I think it was version 7.2). XV was working (but not hardware 3D) using the previous default Debian mesa libs (7.0)
