KWM Switch causes logout

[Mark Smith]

I have a 2x1 KVM switch between my work laptop (win10) and my Ubuntu 24.04 (noble) desktop.

When I switch from Ubuntu to the work laptop - whether I have locked the screen or not - the Ubuntu session logs me out.

I had originally thought it was rebooting the desktop, but using the uptime command, I can see that the machine have been online since my last manual reboot (this morning - I have rebooted a number of times over the last few days to try to clear the issue).

Everything worked fine when the desktop was on Ubuntu 23.10.
