Check the xorg.conf in the "Module" section there should be a line: Load "glx" if it's not there then insert it. If it is there look at /var/log/Xorg.0.log to see if there are any error messages when it tries to load it Installing glxutils and running glxinfo will also help you determine what is going on.
