Two or three days ago, I found my screen hadn’t powered down after the
set time. I eventually fixed it by altering the Screen Energy Saving
setting and re-booting a couple of times. Then yesterday evening, after
another re-boot, the problem reappeared and I’ve been unable to cure it.
Temperamental behaviour of the power settings has been a problem for
many years but this is the first time that I’ve been unable to fix it by
altering the setting and rebooting. Any suggestions as to what else I
can try?

Thanks for the thought but I don’t use VirtualBox. Nothing has changed
regarding what applications I’m running. I’ll just try tweaking a few
things in the hope that I strike lucky; just altered screen locker as
well as power setting and will now wait and see.

And now screen-locker doesn’t work either! Sigh!
Tried another user on this machine and that had no trouble. Realised
that user was still using FF as a web browser whereas I’d switched to
Chromium for this one a few weeks ago. Tried logging on as myself
without launching Chromium and power-saving worked OK. Then launched
Chromium and the problem returned. Could it be Chromium to blame, in
which case why didn’t the problem appear immediately I started using the
application a few weeks ago?
As the nouveau driver had given a variety of problems in the past I
thought I’d give the nVidia driver a go but all that achieved was what
looked like a disaster for Chromium, though a restart of that
application sorted it out.
Still a few more things I can try so not giving up yet.

Those ‘few things’ involved trying an earlier version of 42.2 then 13.2
on this machine but results the same. Then I replaced Chromium with
Opera, using the same mass of windows and tabs, and the problem went
away. Now I just don’t see how something in, or related to, Chromium
could have caused this problem. Any ideas?
Well my point was not specific about VirtualBox but that some programs may prevent the powerdown. Like running a movie in the past prevented start of screen saver.

OK, sorry for misunderstanding.
Latest is that Opera causes no trouble but then Opera keeps coming up
with ‘The media could not be played.’ Dunno about FF but that’s a
nightmare anyway - one of those where you’re running through treacle.
This all started a few days ago after I’d said how much better Linux was
than Windoze. Murphy’s Law wins out again.
