Angry 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.

If I understand your problem description, you are trying to display your laptop at home on a monitor capbable of only 1024x768 using a 1280x1024 resolution. Your clever drivers are trying to save you from yourself by reverting to a virtual 1280x1024 mode displayed on a physical 1024x768 display.

You could try modifying the following section of your config file:
~~~~~~~~~~~~~~~
Depth 24
Modes "1280x1024"
EndSubSection
~~~~~~~~~~~~~~~

To look like:
~~~~~~~~~~~~~~~
Depth 24
Modes "1280x1024" "1024x768"
EndSubSection
~~~~~~~~~~~~~~~

And then pressing <CTRL><KP-> to switch to the lower resolution when you are at home.
