My laptop I have is a Gateway MX3228. Here are the specs:http://support.gateway.com/s/Mobile/Q106/MagicLC/1008831sp2.shtml Right now ubuntu sets the res size to 1600 by 1200. It is far too big for the screen, half of the screen is off of the display. I need to get the size down to something like 1280 by 800. When I go to the display panel and try to change the size from there the screen screws up. There is multiple desktops that overlap each other, making it impossible to see anything. So I try to change it xrandr, which others have pointed me towards. It tells me can't open display. So I don't know what to do from here. If I change the display settings in the prefrences bar I end up screwing up the screen forcing me to reinstall, and every thing I've done to change the display manually tells me can't open display. Are there some drivers I must get for linux?
