I a terminal, go into superuser mode (su -) and type 'init 3'. That way you can run your XConfigurator. An easier way I found though, is just to edit /etc/X11/XF86Config-4 or /etc/X11/XF86Config. At the end of the file, you should have your resolution information. Here is an example of what I am running:
Code:
Section "Screen"
Identifier "Screen0"
Device "NVIDIA GeForce 4 (generic)"
Monitor "Hyundai DeluxScan 17B+"
DefaultDepth 24
Subsection "Display"
Depth 24
Modes "1280x1024" "1152x864" "1024x768" "800x600" "640x480"
EndSubSection
EndSection Some of this will of course vary depending on your hardware. Once you edit the file, just restart the X server.
