Installing Opensuse 11.0 makes laptop screen go haywire!

I used to have 11.0 installed on an Gateway Laptop running XP on another partition… then I got my new computer running Vista and set up another partition on it. When I try to run Opensuse 11.0 (even using the live boot disk) the screen goes completely haywire as it starts to load Opensuse. I have a million lines and colors dancing around on the screen but nothing else. Why? It never did that with the machine running XP!
Anyone know how to fix this problem? Thanks!

Try doing this:

Pause the boot by moving the down arrow, then back up to the default boot. But now press backspace, it should delete any text where you can see: vga=0x…

Remove all text and now type just the number:
and hit enter

at the login type your user name and then password
now type:
then the root password

now type this:
sax2 -r -m 0=vesa
(N.B. the 0 is a zero not a letter)
now reboot: type: reboot
if you don’t get a gui login
login as user at cli and try this at the cli
