problem startup xorg with dell e773c monitor

[diamond]

After the installation of FC6 everything worked well, but after a certain day (think sunday) when i try to boot FC6, i get an output on my screen from out of frequency range. Has someone had this problem before or also and do they know the solution.

If I boot from the installation dvd and do linux resue and do startx and reboot pc, then everything works fine again for as long i don't restart the pc.

try commenting (#) out the vert and horiz entries in xorg.conf and let it auto detect these settings

type as root

gedit /etc/X11/xorg.conf
