I installed FC3 on a Dell Optiplex GX620 machine and I cant seem to set the screen resolution to anything higher than 800x600. If I do it and restart X windows, the screen becomes black with a little message in the center saying "Out of range" and only way to fix ti would be to go to a console screen, login as root, edit xorg.conf file and delete all resolutions higher than 800x600 in screen set-up line. After that I get the login screen and everything.
Any idea what is this about? Thank you.
