Which I believe forces X to re-initialize itself.
I have the same problem in qemu VMs. I do the equivalent of CTL-ALT-F1 then CTL-ALT-F7 to get the GUI back. It started in the last year so it is something in the system is doing it. Googling wasn't much help. I have put all the settings (in KDE) to not sleep or turn off the monitor to no avail.
