If you install Fedora 11 and find that your X11 display is less than ideal (as in it won’t do better than 800×600) run:

Xorg -configure :1

as root to create a new default xorg.conf.new in /root.

Run ‘X -config /root/xorg.conf.new’ to test the new config. If the display sizes properly, copy it to /etc/X11 and overwrite the existing xorg.conf. This was the only fix I needed in do in order to get a clean install of Fedora 11 going.
