My guess is that you have some Plug-and-Play dialog trying to "help" you and it defaults to 640x480 when it cannot query a monitor. Look for ways to override smart options as are implied by a "default" statement and mode options.

On my feisty (pre-release) system one can change change the default resolution in the Gnome menu: System | Control Center, then click on "Screen Resolution" and select the default. The "old school" (and perhaps simpler) way to do this is by editing /etc/X11/xorg.conf (save the current version first!). You will find a section like this: Section "Screen" Identifier "Default Screen" Device "Intel Corporation Mobile Integrated Graphics Controller" Monitor "Generic Monitor" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1680x1050" "1400x1050" "1280x1024" "1024x768" "800x600" "640x480" EndSubSection EndSection For each instance of the line "Modes" insure that you have only the resolution(s) that you want.
