Thread: Screen no longer powers down.

  1. #1

    Default Screen no longer powers down.

    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?

    For what it is worth my screen blanks but does not lock if I have VirtualBox running but does with other programs.

    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.
