[xubuntu-users] Weird behaviour of light-locker

I had experienced the same issue with Xubuntu 18.10. Here are the 2
solutions that worked for me:

   1. Installing gnome-screensaver (which required no dependencies) and
   unchecking light locker from startup applications.
   2. Installed Xubuntu 18.04 which did not have this issue.

This is the reply I got:

testing is underway for an xfce-specific screensaver:


The problem you describe, however, is probably related to
power-management. Make sure your have either power manager or
light-locker in control of separate functions -- that is, that the two
don't overlap with each other in trying to control the same thing.
