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. > I get a similar problem on my laptop that has a Synaptics touchpad.

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... -- Claude Jones Bluemont, VA, USA
