The log went on to record the fact that I unplugged my mouse and plugged
it back (I first thought that was the problem), so the system wasn’t
completely frozen, only the screen was (and Ctrl+Alt+F1 did nothing). I
missed the chance to attempt an SSH connection, should I try that and do
anything in particular in case the problem reappears?
