Brad,
Can you please suggest the easiest way to switch? I have had nothing but 
hassle from the nvidia driver. Or maybe it's my card dying ;-) it seems to 
throw a spurious interrupt every day or sometimes more frequently, that 
requires a complete X and applications restart to recover from. I suspect 
the nvidia module has to get unloaded to clear this problem. (I just tried 
a new nvidia driver, well see...)
What resolution are you running?  Your monitor does 1920 x 1200 but the card 
is not really built for this high of a res.  If you are running a really high 
resolution you should try using the DVI output instead of vga through a KVM.
I'd second this. I have yet to get clean 1600x1200 video ( at 75 Hz+) 
through any of several KVM switches I have tried despite their box claims 
to the contrary. There's often ugly ringing in the video - looks like 
impedance mispatches soemwhere. So I usually connect the two inputs on my 
monitor to the two computers (when I'm only using two) and using the KVM 
switch for keyboard/mouse only.
I would be suprised to see anything but a really high end KVM switch pass 
1920x1200 cleanly - but am eager to hear of recomendations to the 
contrary from list members. I'm currently using a Trendnet TK407  with 
similar (poor) results to others.
cheers,
Brett
