Monitor Notes For Linux
I could only get the default display of 640x480 to come up. I couldn't even select another resolution. Here what you do.
Take a look at /var/log/Xord.0.log
It will most likely say hsync out of range
Edit the Monitor section of /ect/X11/xorg.conf and include the following lines
HorizSync 25-65 VertRefresh 25-60
Of course you should specify the values for your system. Finally, don't expect all resolutions to work. For example 1024x768 didn't work for me, but 1024x1280 worked great!
