Description Pete Graner 2006-07-06 16:26:34 UTC

Description of problem: While running GL based apps the error:

glxgears
libGL warning: 3D driver claims to not support visual 0x4b

glxgear runs in this case, but compiz will not:

compiz --replace gconf
libGL warning: 3D driver claims to not support visual 0x4b
compiz: No GLXFBConfig for default depth, this isn't going to work.
compiz: Failed to manage screen: 0
compiz: No managable screens found on display :0.0


Version-Release number of selected component (if applicable):
[pgraner@meatwad ~]$ rpm -qa | grep mesa
mesa-libGLU-devel-6.5-13.fc6
mesa-libGLU-6.5-13.fc6
mesa-libGL-6.5-13.fc6
mesa-libGL-devel-6.5-13.fc6


How reproducible: Started with todays rawhide mesa and kernel update.

Additional info: I tried the previous kernel with the new mesa packages and
still get the error. If I roll the mesa back to the previous version it works.
So I don't think its a kernel issue at this point.

What driver and architecture?

As a shot in the dark, does it go away if you add -fno-strict-aliasing to the
OPT_FLAGS? (This is more for the X team's benefit, but if you (Pete) want to try
it, go for it -- it's an easy mesa.spec modification.)

WORKSFORME on AMD64/R200 with everything I tried (glxinfo, glxgears, glthreads,
IOQuake3, UT2004 Demo).

Can you still reproduce this with mesa 6.5.1 packages?

Wen't away sometime ago. Just forgot to close out the bug. Sorry.
