Remove the KVM completely.  Then configure X and test it.  Then 
put the KVM back.  If the operation of X with the KVM does not 
match the operation of X with the KVM, then buy a new KVM.

By the way, any setup which is using a KVM switch is officially 
unsupported unless any problem experienced is reproduceable on a 
fresh booth with the keyboard, video and mouse plugged directly 
into the computer.

Hope this helps.
