I''m running RH9 w/KDE and revently installed the nVidia drivers for my GF 2 MX. After that my 3D screensavers stopped working for non-root users. root still runs them fine. I looked on google but couldn''t find anything about this. Any ideas? Exume my speling.

NVidia''s drivers add some devices to /dev that all begin with nvidia. Check the permissions on those devices. In my case, they are root:video, so any user who wants to use them must be in the video group (or you could just chmod a+rw them, I guess).
