Here we go!
/usr/bin/xflock4 is a script expecting a value by
xfconf-query -c xfce4-session -p /general/LockCommand
which returns nothing on my machine.
Apart from lightdm on my machine the packages slock and xlockmore are
installed and before xflock4 stopped working, it seemingly used
xlock -m
Hi,
usually I lock the screen of my openbox sessions (no DE) on demand by
running xflock4 .
Today I locked the screen using dm-tool lock , since xflock4 fails.
I don't know when it exactly stopped working. The time frame is between
the beginning of last week, until today.
