Well I didn't manage to wake the screen (in the end, I just did a
"systemctl reboot" from a different virtual terminal on the same

I *have*, however, worked out what the cause is:

Firstly, I should explain that I prefer to work by logging-in on a
virtual terminal and then, *if* I want x, I run startx myself. In
order for this to work, I had changed systemd's default from
graphical.target to multi-user.target by running:

sudo systemctl set-default multi-user.target

I've discovered that if, on the xfce power manager applet, I set
"Automatically lock the session" to "Never" and I uncheck the "Lock
screen when system is going for sleep", then the problem does *not*
occur i.e. I can always wake up the screen by moving the mouse
whenever the screen sleeps etc.

Success! (Of sorts!)
