Hi,
I ran xrandr on the same VGA screen with my desktop, and it looks like the modes are incorrectly detected with my laptop.
Here are the modes detected with the desktop (amd graphics) :
default connected 1680x1050+0+0 0mm x 0mm
   1680x1050 60.0*
   1440x900 60.0
   1400x1050 60.0
   1280x1024 75.0 70.0 60.0
   1280x960 60.0
   1280x768 60.0
   1280x720 60.0
   1152x864 75.0 70.0 60.0
   1024x768 75.0 72.0 70.0 60.0
   800x600 75.0 72.0 70.0 60.0 56.0
   720x480 60.0
   640x480 75.0 72.0 60.0
   640x432 60.0
   640x400 75.0 60.0
   512x384 75.0 60.0
   400x300 75.0 60.0
   320x240 75.0 60.0
   320x200 75.0 60.0

Here is the xrandr output with laptop (intel gm965) on same screen :
VGA connected (normal left inverted right x axis y axis)
   1280x1024 75.0 + 60.0 60.0
   1680x1050 59.9 + 60.0
   1600x1024 60.2
   1400x1050 70.0 60.0
   1440x900 75.0 59.9 60.0
   1280x960 60.0 60.0
   1360x768 59.8
   1152x864 75.0 75.0 75.0 70.0 60.0
   1024x768 75.1 75.0 70.1 60.0
   832x624 74.6
   800x600 72.2 75.0 60.3 56.2
   640x480 75.0 72.8 75.0 60.0 59.9
   720x400 70.1

I tried gm965 with another screen, and the screen displays "mode not supported error".

Just to let you know, I managed to make it work few month ago when Ubuntu beta 8.10 came out (it wasn't easy as I had to plug, restart X and other stuff), but it broke out since. I didn't say it because I'm still trying to get a working version (I spent a lot of time trying to downgrade different package but still unsuccessfully).

Bye
