Description of problem:
NVIDIA drivers 4496.
glxgears show warning:
Xlib: extension "XFree86-DRI" missing on display ":0.0".
For this driver the Load "dri" in XF86Config is
commented out, as it doesn't need it. There doesn't seem
to be any averse effects. All OpenGL apps seem
to work. However on RH9 there was no such warning.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install NVIDIA proprietary drivers
2. run glxgears
From the mailing list:
It seems that the files in /usr/X11R6/lib/tls must be removed.
It did it and the warning does not occur anymore.
This is not a bug. Please join our mailing lists for technical support
help, and read the archives.
Actually, that is not the correct solution.
"rpm -e --nodeps XFree86-Mesa-libGL" is the proper solution, at
least until Nvidia fixes their driver installation to be correct
and rpm friendly.
