I am using Fedore Core 3 on a x86 dual-boot PC, and enjoying it greatly.
However, I recently updated the Kernel using Up2Date (I know it's just a fancy yum interface, but stay with me.) and reinstalled the NVidia drivers from the website.
I know from experience that if I don't, they simply don't work.
I was happily playing my newly updated version of Unreal Tournement 2003 last night enjoying its lack of shudder which I don't miss at all from XP.
However, this morning - suddenly - I no longer have GLX running. UT2003 just exits and when I run it from terminal I get "GLX not loaded".
Say now! - I run glxgears and get the same, instead of a nice perky 2500+ fps.
I went to reinstall the NVIDIA drivers just incase, and get mutiple "usr/lib/libGL.so.1" "usr/lib/libGL.so" etc. symlink missing errors.
I had a look at the README for the drivers (thank you NVidia...) at appendix C and I can see a happy shiny list of programs that are installed, but have no idea what to symlink or precisely how. I know the command "ln -s" is used for that, but what I'm supposed to put and in what order exactly I have NO idea!
