Bug#900373: libkscreenlocker5: kscreenlocker_greet may be frozen on resume from suspend to Ram

[Alex Dănilă <nuorama@gmail.com>]

Package: libkscreenlocker5
Version: 5.12.2-1
Severity: important

Dear Maintainer,

After resume from suspend, kscreenlocker_greet is most often frozen and cannot be interacted with. 
This is a dual display setup, and, when this bug happens, the left display („primary” in systemsettings)
is black, the frozen kscreenlocker is only shown on the right display. Killing kscreenlocker_greet 
from a root terminal will spawn a new kscreenlocker that behaves normaly.

This is somewhat similiar to #852162, which is worse but no longer happens to me.

Alex
