After the upgrade to RedHat 6.1 LinuxQuake 3 would only start up in a small 300x200 window. I have a Voodoo 3 3000 and had no problems running Quake 3 at 1024x768 before. Other 3d apps also segfault (including Unreal Tournament) or lock the machine (often taking keyboard focus so that a hard reboot is necessary)
The libGL.so and glx module for Riva TNT ( from nvidia's site ) doesn't seem to work with RH6.1 , they did work with RH 6.0. Im talking from memory, but I think that the server dumps core when a program tries to use OpenGL ( I only tried Quake2 ). Could be some glibc 2.0 <-> 2.1 incompatibility.
RHL 6.0 and 6.1 use compatible glibcs. What version of RHL does the libGL that nvidia offers claim to support?
