    Issue with a kvm console

    Hi folks.

    Today I installed a kvm console into our rack and connected all the servers up.

    The windows servers work beautifully. The linux ones however all look like this:

    (sorry about the quality)

    (The distortion constantly changes)

    It's running Scientific Linux 6.3.

    KVM is: Lindy 19" Modular KVM Terminal no: 21615 with KVM Switch - U16C Modular no: 39531

    Video is connected via VGA, keyboard/touchpad via USB.

    I can't reboot the machines as they are in use 24/7 so if they require a reboot I'll have to arrange for downtime.
    Any ideas?

    If I unplug and reconnect the KVM it's clear for about 2-3 seconds then becomes distorted again.

    Any ideas? I'm at a loss.

    Nobody got any ideas?

    Is there a more relevant section I should post this in?

    What's the resolution like on the linux boxes.

    Does look like it's a graphics problem. Refresh rate sat too high or its out of range.

    Windows will adjust automatically when a different monitor is plugged in.

    Not sure about the resolution, the boxes just have tty's and don't have a modeline set. The monitor reports the frequency at 72hz though which seems a bit high.
