I manually wrote "600x800" in the xorg.conf to test if i was able to change the resolution, but didn't work.

Support for Ubuntu 10.04 will expire in a few months from now.

I suggest testing Ubuntu 12.04 LTS in a LiveCD session. If the monitor works fine in Ubuntu 12.04 LTS, then I suggest performing a clean install of Ubuntu 12.04 LTS.

If similar problems occur in Ubuntu 12.04 LTS, then I suggest sending us the full Terminal output of the command in the following procedure:

Actually i use backtrack 5 r3 And is based in that ubuntu version :/

Backtrack is not supported here.

It has its own support forum here:

Can you help with this problem?
