I've been having similiar problems as well creating MythDora. I'm using the
7676 Nvidia driver version and I'm getting the same glx errors. There are
two workarounds that I've found that work. The first is to comment out glx
in xorg.conf as someone had already mentioned and the second fix I found that
works was to remove the nvidia-graphics7676-1.0_7676 rpm then re-install
it. After that all seems to work fine. I realize not all will be using an rpm based
install but thought I would throw it out anyway. I still can't figure out why it's
not installing correctly.
