I have an old desktop that I installed Ubuntu on, the installation went well. When I rebooted my computer I get the following info on the screen:

change display mode to 1280x.... 60.00Hz

My graphics card is an ATI HD 5450

I have tried the fix at the following url: http://www.myapitips.com/2011/11/02/how-to-change-monitor-resolution-in-ubuntu-11-10/

However when I try something like randr my computer gives me an error: can't open display.

Any ideas?
