Extreme Tux Racer won't launch on my box if started by a regular user.
It *does* works when logged as root as per Jserink advice in gentoo forums (see below).
As normal user, a command line start of etracer immediately exits with the following message:
"Couldn't initialize video: Couldn't find matching GLX visual (Resource temporarily unavailable)"
This problem occurs both in Ubuntu Natty (11.04) and Fedora 15
My OpenGL runs with MESA on a DRI Mobile Intel GM45 Express Chipset and other OpenGL apps work fine.
