Latest light-locker update 1.9.0-3 is broken.,
Additional info:
* light-locker 1.9.0-3

Steps to reproduce:
After entering password on lock screen it goes just to black screen instead of desktop. After killing light-locker process in console and switching back to vt7 there is unlocked session, though. Downgrading light-locker to 1.9.0-2 fixing this issue, so it seems to be localized in this changes:

I am having the same issue. I ran light-locker with the --debug flag, and it is throwing errors about dbus (see attached log). I reported the issue upstream as well to the author of the pull request with these three commits (

I'm having the exact same problem, on both my desktop and my laptop. Running official arch linux, with manual installation and xfce4 + lightdm-gtk-greeter. Downgrading to light-locker-1.9.0-2 "fixed" the problem.

Yep, confirmed exact same issue here. If locking is urgent, and you just happen to be using xfce4, this is a temporary workaround:

$ sudo pacman -Rs light-locker
$ sudo pacman -S xflock4
$ xfconf-query -c xfce4-session -p /general/LockCommand -s "dm-tool lock"
$ xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/lock-screen-suspend-hibernate -s true

Yes same problem for me, ethier I have a black screen either I have the notification screen (this session is locked...etc).

Those commits were mine, and it seems an update to systemd/lightdm has broken my method of grabbing the systemd session.
I have committed a fix that works with pantheon and XFCE.

I also saw some complain about the problem with i3, I didn't test the fix for that WM, but I see no reason as to why it should break there.

This is the commit in question:
