[Pkg-xfce-devel] Bug#868087: light-locker: Locking screen with light-locker crashes system to blinking cursor

[Max Zhao]

Package: light-locker
Version: 1.7.0-3
Severity: important

Dear Maintainer,

when locking the screen using either the command 'dm-tool lock' or 'light-locker-command -l', the screen will black showing only a blinking cursor. Switching to TTYs is not possible and only a restart will resolve the situation. This happens for every execution of the aforementioned commands.

Also when issuing a 'light-locker-command -a', the screen will not be turned off, instead the following error message is generated:
** Message: The screensaver failed to activate.
