Actually, it works fine, except when I go through a KVM
KVMs are not all created equal.
When I set up my VM system for gaming, I had a virtual Windows machine
connected to a GPU card, while the host Linux system used the internal
GPU on the motherboard. Both were connected via a KVM to a single
monitor and I could switch between them.
Except that it didn't work. I finally traced the problem to the KVM not
maintaining a live signal on the "disconnected" input port, meaning
that the VM thought it had no video.
I finally got a different brand KVM which does maintain all output
ports in a live condition, and the problem went away.
Obviously a keyboard connection is not the same thing, but if one of
your systems thinks it has no video output, it might not want to wake
up. Just a thought.
