View Full Version : [ubuntu] Ubuntu 10.10 3D Acceleration problems on ATI Radeon 8500LE

I hate having to possibly bring up an already solved problem, but I could not find a decent working solution in the forums.

For the most part, I'm having problems with my ATI Radeon 8500LE 128MB video card under Ubuntu 10.10 using Gnome for the front end. What's odd is that there is some general slowdown when compared to 9.04, but also 3D acceleration seems to be a bit weird for me as well. If I start glxgears, everything seems to work and the framerate is capped at my monitor's refresh rate (75Hz); but, let me open something like Blender and try to rotate the camera around and the entire system hardlocks and is unresponsive to any sort of keyboard commands, necessitating a forced power down.

Checking the logs (kern.log specifically), the only thing I can generally find that seem to point in any general direction is the following when another OGL app is run:
Oct 27 17:23:37 mycomputer kernel: [83586.678932] [drm:r100_cs_track_texture_check] *ERROR* No texture bound to unit 1
Oct 27 17:23:37 mycomputer kernel: [83586.678940] [drm:radeon_cs_ioctl] *ERROR* Invalid command stream !

Again, Blender and it's subsequent lockup does not generate any anything in the logs.

So, does anyone have any ideas on where to proceed in finding a fix or should I file a bug report and wait for Ubuntu to fix the problem?:confused:

Adding to my troubles, I think I figured out some of why there's so much slowdown when trying to view webpages.

Watching the task manager in XFCE, I noticed that the flash plugin, firefox and an X session were maximizing my CPU. See attached image for details.

Is there any chance that the ati drivers (ppa and stock) are at fault here or is Flash and Firefox somehow at odds with X?:confused:

Got something a little more interesting to report. After trying to use Blender again, then rotating the mouse a bit, again it crashed X and blanked out the screen. Though, on the other hand, it seemed to have forced my account to logout; I could hear the login screen prompt sound. Going back to check the log, I found the following:
