But the contents of /etc/X11/xorg.conf have not changed. The file is
owned and writeable by root. Nothing shows up in /var/log/messages,
except authorization stuff, which succeeds.
Then I tried changing the hardware tab/monitor type. Sadly, no
pre-setting for my Dell screen, so I choose generic LCD panel
1280x800, since that is what my screen is. Again,
system-config-display acts like it is saving it and backing up old
settings, but nothing changes and no backup written.
I ended up editing the file by hand. Here's the file I have now:
Section "ServerLayout"
Identifier "single head configuration"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
EndSection
Section "InputDevice"
# keyboard added by rhpxl
Identifier "Keyboard0"
Driver "kbd"
Option "XkbModel" "pc105"
Option "XkbLayout" "us"
EndSection
Section "Monitor"
Identifier "Monitor0"
ModelName "LCD Panel 1280x800"
HorizSync 31.5 - 50.0
VertRefresh 56.0 - 65.0
Option "dpms"
EndSection
Section "Device"
Identifier "Videocard0"
Driver "nv"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1280x800" "1024x768" " 832x624" "800x600"
"720x400" "640x480" "640x400" "640x350"
EndSubSection
EndSection
system-config-display doesn't show the 1280x800 option. It does let me
switch between those modes, though of course I can't choose 1280x800,
since it is missing from the menu.
I'm confused. Why won't system-config-display let me save my settings?
Why does it override the contents of the config file? Do I need to put
some sort of usemodes or mode entry in the monitor section?
Thanks for any clues.
Dave
