Dell D630 fc9 can't change screen resolution with system-config-display

[Dave Burns]

I select menu item System/Administration/Display and authenticate. I
select a different resolution from the resolution menu. I click 'OK'.
A dialog box pops up:

"Display settings changed
You need to log out and restart the X server for the changes to take effect.
Coinfiguration was written to /etc/X11/xorg.conf, original
configuration saved as /etc/X11/xorg.conf.backup"

I click okay, open up a terminal window. ls -la shows
/etc/X11/xorg.conf was modified. /etc/X11/xorg.conf.backup does not
exist.

If I choose the highest resolution setting shown (832x624),
/etc/X11/xorg.conf has a screen section that looks like this:


Section "Screen"
       Identifier "Screen0"
       Device     "Videocard0"
       DefaultDepth     24
       SubSection "Display"
               Viewport   0 0
               Depth     24

       EndSubSection
EndSection

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.

Perhaps I need a tool called nvidia-xconfig? nvidia not compatible
with system-config-display? Unfortunately, I apparently need to use
livna and upgrade my kernel to even try it.

System X configuration is separate from user-preferred screen
resolutions.  Look in your personal hardware preferences in Gnome, I
don't know what KDE does, nor other managers.

Have you tried the nivdia drivers included in the livna repo.
I'm using the Ati driver from livna.

solution - I used the gui add/remove software front end to yum.
Command line yum search told me something that confused me, made me
think I needed to upgrade my kernel to a version apparently not
available at any repository available to me. The gui showed a bunch of
different nvidia-config packages and showed which kernels they were
compatible with, so I could find the one that matched my installed
kernel.
