Please put in plain English, how do I install an ATI Radeon video card in my Ubuntu system. I am already the system with the on board and love the OS. I am not good at using Ubuntu yet, I am at the playing with it stage.
I do not have a driver disk. I have tried looking for linux versions of the drivers, but no luck, just windows versions. I tried inserting the card and booting, but it comes up with it is running in low resolution mode and then I end up with brown bars across the screen. I was using the built in video, but I need DVI for the new monitor. If it helps at all I am currently using a 17 inch CRT monitor.
