There are two pieces for resolution--
what the card can 'produce'
what the display can 'consume'
Sounds like the card might be limited to what it can produce to drive a
monitor. For instance, the x60 I have can only do 1024x768 internal and
external. I can connect to my 1600x1050 but it displays 1024x678 with
What distro you have will also allow us to suggest how to tweak,
assuming the video card can do it. Google the video card for info.
The newest Xorg appears to 'generate xorg.conf' at startup as there is
no file on the system anymore. You can create one and it can be used,
but by default, there is no 'saved' xorg.conf
