LinuxQuestions.org - Screen Does Not Sync Correctly

Here is my problem,

I am running SuSE 9.1 on a laptop
Specs:
Processor - Pentium 4 2.8 GHz
Video - ATI Mobility Radeon 9000
Current Resolution - 1280x1024

The display on the laptop works fine...when I plug
a my monitor at work into the display it works fine
(ViewSonic Brand)...but when I plug my monitor at
home (Samsung SyncMaster 955df) into the laptop
my desktop scrolls in every direction (The screen is
larger than the actual monitor size).

How do I fix this problem...?
I've tried moding the XF86config file...using Yast to
change the display settings...nothing works!!!
I've made sure the virtual display is disabled.

Also, the laptop screen still works fine...and both work
fine running up through the startup display.

Here is my XF86config file generated by Yast:

Can someone help me out...?

Thanks.
