Don't mean to ask a stupid question, but I will - you did try the "Screen and Graphics" dialog first didn't you?
Yep sure did, it was useless. Even though it recognised my video card and my laptop monitor I couldnt get it to display 1400x900 properly on my external monitor.
It would go into 1400x900 mode but would not fill the whole screen for some reason. I even tried entering my monitors hsync and vsync settings direct which didn't change much
Really wanted to try out Ubuntu and compiz fusion but I just can't deal with my monitor not working
