I am quite new to Linux. I have a Compaq presario 1500 laptop. I am currently running fedora core 6. my problem is when my computer loads and the desktop loads it looks looks like 2 separate screens. it looks like the screen isn't big enough and it tiles the screen. i have a ati raedon 7500 mobility card. i fixed the problem once but i can not figure out how i did it. if anyone can please help me out it would be greatly appreciated.
