i have a freshly installed Xubuntu 12.04 on an old computer. I'm fairly new to working with ubuntu (i know how to use google) and cannot seem to get the right resolution with it connected to a 16:9 lcd TV (the resolution i want is 1280x720, or anything that comes close)

When trying to create a new resolution with Xrandr it says "failed to get size of gamma for input" Trying to configure Xorg.conf it says that the file doesn't exist, and when trying to create a new one it says: Fatal sever error: server is already active for display 0, etc.

(for info) with lspci i got; $ lspci | grep VGA

01:00.0 VGA compatible controller: VIA Technologies, Inc. CN700/P4M800 Pro/P4M800 CE/VN800 Graphics [S3 UniChrome Pro] (rev 01)

So any tips for the right way to configure Xorg, Xrandr, getting the right drivers, or should i give up since it's connected with a VGA cable? (or maybe a program to "fake" a resolution?)
