I vaguely (very vaguely) remember having had similar troubles with an old NVidia card a few years ago, and this is an old NVidia card. I also remember something strange happening. Normally when I install a desktop, I begin with a minimal bootable system (everything unchecked in the installer). Then I 'yum groupinstall "X Window System"' and go on configuring X. Only when TWM is working OK, I install some desktop environment (GNOME, KDE, XFCE) and the apps on top. After I had installed the driver and fired up TWM, I wanted to test 3D abilities, so I typed 'glxgears' in TWM's xterm, but I got an error message about some missing GLX extension. I didn't investigate this further, since it's an install for an office user, and I thought, let's install and configure all needed apps, and we'll see for Compiz later (even the most serious SOHO users love Compiz) :oD Niki
