Same problem. I took some of the settings from my FC6 xorg.conf and added them to conf in F7. Here are the changes I made to /etc/X11/xorg.conf to get things working (don't forget to back yours up before editing):
Added this section:
Code:
Section "Monitor"
Identifier "Monitor0"
ModelName "LCD Panel 1280x800"
### Comment all HorizSync and VertSync values to use DDC:
HorizSync 31.5 - 90.0
VertRefresh 59.9 - 60.1
Option "dpms"
EndSection
Added this line to the Screen section block:
Added this line to the Display subsection:
Code:
Modes "1280x800" "1152x864" "1024x768" "800x600" "640x480"
So there's no confusion, here's my entire working xorg.conf:
Code:
# Xorg configuration created by pyxf86config
Section "ServerLayout"
Identifier "Default Layout"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
EndSection
Section "InputDevice"
Identifier "Keyboard0"
Driver "kbd"
Option "XkbModel" "pc105"
Option "XkbLayout" "us"
EndSection
Section "Monitor"
Identifier "Monitor0"
ModelName "LCD Panel 1280x800"
### Comment all HorizSync and VertSync values to use DDC:
HorizSync 31.5 - 90.0
VertRefresh 59.9 - 60.1
Option "dpms"
EndSection
Section "Device"
Identifier "Videocard0"
Driver "vesa"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1280x800" "1152x864" "1024x768" "800x600" "640x480"
EndSubSection
EndSection
Good luck!
