Hi:
I've been trying to debug a problem that cropped up recently between the
switch to Xorg server 1.5 and Mesa 7.4 in Ubuntu 9.04. MythTV 0.21 (based
on QT3) would no longer open properly on machines using RADEON DRI.
Something similar happened recently for those using swrast, and it turned
out that a patch to expose more fbconfigs in swrast by Eric Anholt solved
the problem. I took this idea and wrote a small patch doing similar in
RADEON dri, and sure it enough it solved the problem there too.
For more information, you can refer to the existing Ubuntu bug report (
https://bugs.edge.launchpad.net/ubuntu/+source/mythtv/+bug/341898).
Regards
