Recently I downloaded Tremulous and tried to install it. I ran the the installer smoothly, with now error messages, but when I tried to run it for the first time I got this error message:
Sys_Error: GLimp_Init() - could not load OpenGL subsystem
The first thing I thought was that there was something wrong with my driver, so I went to the NVidea site, and downloaded this driver - http://www.nvidia.com/object/linux_display_ia32_1.0-9746.html - for my Geforce 6600.
So I went into the command line, to run the installer for the graphics card, but every time I tried to install it I got an error about how it couldn't find the kernel source tools necessary to compile the thing it needed. Then I went into the package manager and installed the 'kernel-devel' package, but I still got the same error when running the driver installer. I guess this is more of a linux question, but if anyone has gotten this to run on Fedora, I would love some input.
Its not just a Fedora problem. I get the same error on Debian with the latest nVidia drivers on my laptop. Did you try the beta driver?
Don't install the nvidia drivers from their site. Use the RPMs from Livna or FreshRPMs
