I would suggest further research. I have to disagree on the above statement. 
While Belkin KVM's do work, 'some of the time', they are in my experience 
flaky - we have removed them from our approval list. They are not just 
problematic with Fedora - we have had many problems with them in Windows only 
scenarios. Do a little searching on the web and you'll find a lot of negative 
info about Belkin.

There appears to be an issue with sync signaling and how devices lock back up 
- whether this is an equipment problem with manufacturers not closely 
adhering to specs, or a Fedora problem, is not completely clear. Probably 
some of both, but there are certain brands of equipment that work perfectly 
with Fedora - I switched to IOGear unpowered KVM's last year, and haven't 
thought about them since - they just work, seamlessly. Your touchpad issue is 
obviously not so easily solved...
