>Description:
I switch back and forth with my startech 2-port DVI + USB KVM switch. Once I've switched "away" and then "back" I often lose control of the system (though video stick around sometimes - frozen). Once I reboot I get a core in /var/crash. I thought you folks might want to take a look.

Let me know how to send the core files. 
>How-To-Repeat:
Switch with a Startech KVM using a Logitech G910 keyboard (a strange expensive beast of a keyboard with many unrecognized keycodes for special keys)
>Fix:
Reset switch.
