this looks like a problem with the OpenGL support.

can you run any other OpenGL program, e.g. glxgears?

what X driver are you using?
try using: glxinfo | egrep '(OpenGL|glx)'

if you installed the nvidia drivers manually
and have updated OpenGL related X libraries (Mesa),
you may have to re-install the nvidia drivers.
the same is true in case you updated the kernel.

it may be worth looking for a solution similar to
what rpm.livna.org does for fedora. i'm running an x86_64
system with fedora core 6 with an nvidia card and
kernel and nvidia-driver/module updates worked smoothly
with 'yum update'. for details see:
http://rpm.livna.org/rlowiki/LivnaSwitcher

hope this helps,
   axel.

p.s.: when replying to a previous post to avoid having to type the
mailing list address, please do not only edit the subject line, but
also remove the not relevant previous post. this will help to avoid
confusion for people searching the mailing list archives. thanks.
