When screen is locked triggered by closing the laptop lid then when user enters
password in light-locker screen goes black(powered/switched off). When screen
is locked not triggered by the closing lid event(for example xflock command
triggered by keyboard shortcut) screen unlocking is working fine tough.
I was thinking that this is a xfpm/systemd bug similar to this one:
https://bugzilla.xfce.org/show_bug.cgi?id=10535 but then I installed
Xscreensaver for a test and it was working fine so I presume this is most
probably light-locker bug.
On the other hand I was using light-locker before(1.4.0-1 version) and it was
working fine but it was at the time when testing was freezed and I had previous
versions of xfpm and systemd(don't remember exacly which versions). When I've
reverted the light-locker package to 1.4.0-2+b1 version but it didn't help.
I've also tried to verify that this issue exist without using xfpm too but
couldn't trigger lock screen by laptop lid through systemd/logind because of
this bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=741491
The workaround that I am using for this issue is "xrandr --auto" command saved
to some keyboard shortcut taken from this bugtopic:
however it is very annoying to do this every time when opening laptop lid and
it does mess external monitor sometimes.
I didn't notice anything extraordinary in journalctl logs, when I will find
time I will try to enable some debug options in light-locker/light-
dm/systemd/xfpm if these are easy to set.
