Just installed xubuntu 18.04. Lock screen doesn't work: when I click in the locker image on the ower right corner of the menu, nothing happens.
Trying to debug it I found out that apparently there is some environment variable missing:
# light-locker
** (light-locker:5830): ERROR **: 14:42:54.829: Environment variable XDG_SESSION_PATH not set. Is LightDM running?
Trace/breakpoint trap (core dumped)
Some extra info:
$ env | grep -i manager
XDG_SEAT_PATH=/org/freedesktop/DisplayManager/Seat0
XDG_SESSION_PATH=/org/freedesktop/DisplayManager/Session0
SESSION_MANAGER=local/fellini:@/tmp/.ICE-unix/1564,unix/fellini:/tmp/.ICE-unix/1564
How do I make the lock screen work?
env | grep -i manager
show?
