Public bug reported:
Everyday, I lock the screen when I'm away from the computer and,
everyday, if I am more than two hours away, the bloody computer freezes
its graphical interface: not the laptop itself, still running, but to no
avail.
Workaround - Emergency Sync + Emergency Umount + Reboot with the laptop
keyboard, as the external mouse and keyboard and the monitors are
unresponsive. The machine is connected and could be accessed via ssh, if
I had another computer at home.
