This sounds like what I'm getting - SuSE 42.3, no raid, doesn't happen
when the power lead is in (but I think the laptop is configured not to
suspend when powered, precisely to avoid exactly this).

It happens to me quite often, unfortunately, but it seems a KDE issue in
that applications work fine, UNTIL KDE seems to get control of the mouse
at which point I can't do anything.

I've got a feeling it's related to wireless networking actually, my
setup is somewhat borked because KDE, systemd, and wifi don't seem to
work nicely together :-(

Cheers,
Wol
