Nvidia Glx
 

In my XFree86 log I get a line saying NVIDIA failed to load GLX or something like that. What does this mean and how can I fix it?

have you installed the nvidia drivers, and not make the correct changes in your XF86Config file? since you didn't mention anything about editing your config file then,
my first guess is that you either didn't add :
to your XF86Config file, or you have :
in the config file and you did not make the change of removing the # in front of
the statement.

Yes I have done that already.
