Diagonal lines apear on screen system freezes

Can you run these commands and post the output?
1. grep -i driver /etc/X11/xorg.conf
     example: Driver "fglrx"

2. lspci
    example: 01:00.1 Display controller: ATI Technologies Inc RV516 [Radeon X1300 Pro] (Secondary)

3. dmesg | tail
    This will output driver messages and tail will show the last 10 lines. If you can look through /var/log/dmesg and /var/log/Xorg.0.log and find any pertinent information about your video card you can clip that too.

These commands will show us what graphics hardware you have installed and what driver the system is attempting to load.

Dear Jeff Rasmussen, Thank you for replying to my question. Since posting
my question my brother has got me to try Fedora which is doing the same
thing by the way with the diagonal line problem. My hope is to find a
solution and to run Ubuntu which I like better.
Hopefully this can help?
