Nvidia Driver Problems?

[Erwin J. Prinz]

Same issue here. "glxgears" looks for a libGL.so.1 library and finds the 
wrong one:

[root at tiger erwin]# ldd /usr/X11R6/bin/glxgears
        libGL.so.1 => /usr/X11R6/lib/tls/libGL.so.1 (0x00590000)

So, that library needs to be removed to detect the NVIDIA libGL.so.1:

rpm -e --nodeps XFree86-Mesa-libGL-4.3.0-42

For me, that solved the problem. There was an earlier post indicating 
that RedHat is in discussion with NVIDIA to solve the problem in a clean 
way.

Best regards, Erwin
