can't change resolution, screen cuts off please help
I just upgraded and I'm about to hurl my computer. The only thing that shows on all screens (boot, desktop...) is a horizontal strip across the screen that takes up about 1/3 of the height. The actual resolution looks to be huge. I can only see part of the top deskbar, and none of the bottom. The screen resolution link in the admin menu is past where it cuts off, so I can't see it to click on it. How can I fix the resolution? I searched a bit and someone said to reconfigure xorg in the terminal, but I just can't SEE enough to be able to do anything. (I'm not on the problem PC right now.) What can I do? Someone please help.
