Public bug reported: I'm running Xubuntu 17.10. After I installed libglib2.0-dev 2.54.1-1ubuntu1, light-locker 1.7.0-2ubuntu1 stopped working correctly, because it couldn't ready its schema (/usr/share/glib-2.0/schemas/apps .light-locker.gschema.xml) anymore, so it couldn't get its settings from the gsettings backend, logging an error message in ~/.xsession-errors:
Schema "apps.light-locker" not found. Not storing runtime settings The consequence of this was: whenever the screen was blanked, it was locked, even though I had configured on Xfce Power Manager: Security => Light Locker => Automatically lock the session: Never light-locker was always locking the session automatically because it couldn't read the settings through its gsettings backend. So, I uninstalled light-locker 1.7.0-2ubuntu1, cloned its upstream git repository: https://github.com/the-cavalry/light-locker built and installed it, under /usr/local, its default. This solved my first problem: light-locker was now able to read its configurations through gsettings, but xflock4 stopped working. Looking at this bug: https://bugs.launchpad.net/ubuntu/+source/xfce4-session/+bug/1537507 I realized that xflock4 was just a shell script, and I discovered that, right at the beginning, it sets its PATH to: PATH=/bin:/usr/bin export PATH So, as light-locker is installed as /usr/local/bin/light-locker, xflock4 obviously cannot find it through PATH. Of course, I could just install light-locker under /usr, but it's standard practice to install locally built software under /usr/local, to avoid conflicts with software installed from the distribution, which is installed under /usr. Therefore, xflock4 needs to be fixed so as to include /usr/local/bin in the PATH variable: PATH=/bin:/usr/local/bin:/usr/bin This will also affects Xubuntu 17.10 and 18.04, because xfce4-session remained at version 4.12.1-3ubuntu3.
