I have had this happen before, but this time I think I finally isolated
the problem. When Desktop Effects are enabled, using alt-tab to switch
between workspaces my system locks up. It also locks up with the desktop
cube effect enabled and trying to switch between workspaces using ctrl-F11.
It does not lock up every time, but the only consistent thing has been
desktop effects enabled. Here is a segment of my log messages for the
time that the system locked up:

So you can see that it repeated the error in the log file several times.
My mouse was responsive, but nothing on the keyboard was responsive, so
I had no choice but to hit the reset button on the computer and reboot.
It seems that the error is related to the nouveau driver for my nvidia
display, and I googled to find that some other people have had related
problems with the nouveau driver (though I didn't see any on SUSE
forums, only other distros).
I am using my desktop (box #1 below) and the driver description is more
accurate to be listed like this: nVidia C61 [GeForce 7025 / nForce 630a]
The big question is this. Is it better to get a proprietary nVidia
driver, and will that make my graphics generally perform better, as well
as not have the system lockups?
The nVidia driver available from the nVidia repositories is
x11-video-nvidiaG02. I sometimes read people not wanting to use
proprietary drivers so I am hesitant, thinking this might cause more
problems than it solves. Any ideas?
