Sorry to bother you with the PM. I've been trying to find an inexpensive KDM switch, that does not have difficulties with new versions of Ubuntu, (one that correctly sends the DCC signal to the computer from peripherals), especially for the computers to read the correct resolution of the monitors. In a post of yours, about 3 weeks ago, you indicated that you have an expensive KVM that worked like a charm. May I ask you which one it is? I have posted a thread requesting known good performers in Ubuntu Forums, but as yet have no responses.
