[Pkg-xfce-devel] Bug#870641: light-locker: screen stays black after closing and opening laptop lid

[G. Milde]

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

Dear Maintainer,

I use xfce on an eeepc laptop. It's configured to hibernate (Bereitschaft)
when the lid closes using xfce4-power-manager.

After updating to Debian stretch, the wakeup fails, the screen stays black
after opening (with some light flashing) and I cannot resume work.

It is possible to switch to a console with Ctrl-Alt-F1 and kill Xorg or
re-start lightdm but this requires loggin in as root and unsaved work in the
session is lost.

The issue dissapears when purging the light-locker package.
