Title:
GLX problems with ATI R200 using UMS
Status in “xserver-xorg-video-ati” package in Ubuntu:
Expired
Bug description:
Binary package hint: xorg
System is a relatively old P4 Celeron, with an ATI 9200 (r200) board.
Mythbuntu Lucid (10.04). Essentially the same problems happen with kernels
2.6.32 (standard), 2.6.34 (Ubuntu builds) and 2.6.34 (custom by me).
Following known problems of KMS with Radeon TV-out (see: Bug 584169),
I switched to UMS by having a modprobe option of "radeon modeset 0".
No GLX problems had been observed with KMS.
The following problems were observed while employing GLX applications:
1. glxinfo runs successfully
2. glxgears runs with no crashes, but its window is black, and frame rate is
about 2.5 times higher than the frame rate with KMS.
During the running of glxinfo, the following lines are added to dmesg:
"glxinfo:2693 freeing invalid memtype d02f2000-d0302000"
3. xbmc is very slow.
