I'm on Xubuntu 14.04. When I originally upgraded, I had the problem of both light locker and xscreensaver running simultaneously. After that was fixed, light locker has been running smoothly.

But, recently, I noticed my screen on after I was gone all day; it was on when I woke up the next morning; etc.

I tried changing settings, rebooting, looking for other screensaver-like processes, checking that the command args would update when I made changes in the settings UI, etc.

I can manually lock the screen with light-locker-command -l, but I don't remember to do that every time.

I wasn't able to find other askubuntu questions that address my situation.

Could there have been a problem with a recent update (I apply them appx. once/week)? Or, are there other things I should check?

Switch to xscreensaver.

$ sudo apt-get remove light-locker
$ pkill light-locker
$ sudo apt-get install xscreensaver

Edit the screensaver settings (click yes/okay if asked to start the daemon):

$ xscreensaver-demo

Open the XFCE Power Manager ("Power Manager" from the "Settings" menu) and de-select "Handle display power management" in the "Display" tab.

I found this suggestion on a discussion group, but can't find the reference at the moment (thank you to whoever suggested it!)

  1. Log out
  2. Switch to a terminal (e.g. Ctrl-Alt-F1)
  3. Log in to the text terminal
  4. $ rm -rf ~/.cache/sessions/*
  5. $ exit
  6. Return to the graphical environment (Alt-F7)
  7. Log in as normal

Now, I'm getting screen saver & locking as configured via the xfce4 power manager.
