attempting use of KVM switch a disaster

A friend of mine uses that same monitor (Samsung SyncMaster 940BW) and has
no problems with it in gutsy. Isn't that a widescreen monitor? His is
running at 1440x900, so I'm not sure how well 1024x768 would run on it.

As in the link Brian sent, you need to edit xorg.conf with superuser
privileges, so from the command line you'll want to enter:
sudo nano /etc/X11/xorg.conf

If you want to specify a resolution of 1024x768, look for the "Screen"
section and enter this before the "EndSection" that ends that section (you
may want to comment out any pre-existing "Display" subsections):
SubSection "Display"
    Depth 24
    Modes "1024x768"

To specify the refresh rate, look for the "Monitor" section and enter this
inside it:
HorizSync 30-81
VertRefresh 56-75

(those are the ranges for the SyncMaster 940BW, it may be necessary to
specify a single value for each as I did with mine, but then again my
monitor only had single values in its specs)

After those changes are made, you can save the file doing a Ctrl+O, and exit
with Ctrl+X. Then restart the x server with Ctrl+Alt+Backspace.

Oh, and you can always test it by hooking the monitor directly up to the
computer to make sure it works. If it does, then you should make a note of
what resolution and refresh rate it's using.

Hope this helps,
