Well I do not know where the default screen resolution is set, nor do I know
why your settings are not sticking. However a look at /etc/XF86Config-4
shows the screens section contains this in my config
Section "Screen"
Identifier "screen1"
Device "NVIDIA GeForce 256 (generic)"
Monitor "Nokia 446Xpro"
DefaultColorDepth 16
Subsection "Display"
Depth 8
Modes "1280x1024" "1024x768" "800x600" "640x400"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 16
Modes "1280x1024" "1024x768" "800x600" "640x480"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 24
Modes "1024x768" "800x600" "640x480"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 32
Modes "1024x768" "800x600" "640x480"
ViewPort 0 0
EndSubsection
EndSection
Notice the colourdepth 24 section has 1024x768 as its max resolution.
Try setting the DefaultColorDepth parameter to 16 or 32 by editing the file
and see if that improves things. (Just restart X. No need to reboot. This
isn't Windows :-)
I believe you can add extra resolutions simply by adding them to the Modes
list, but I have never tried it, and if you were to add a resolution which
causes the scan rate of the monitor to be too high you could fry your
monitor.
