[Pkg-xfce-devel] Bug#846278: light-locker fails to unlock

[Juha Jäykkä]

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

Dear Maintainer,

Light-locker cannot unlock a locked screen with lxqt. When lxqt invokes
light-locker to lock the screen, the usual "you will be redirected" message
and subsequent lightdm login screen appear. Typing in the password leads to
a successful pam authentication:

Nov 29 19:26:19 rigel lightdm: pam_sss(lightdm:auth): authentication success; logname= uid=0 euid=0 tty=:1 ruser= rhost= user=juhaj

but that's the last bit which works as expected.

Next, I get a black screen, which is soon replaced by text-mode black screen
with a blinking text-mode cursor at the top left corner. The actual X session
is never recovered.

It can be recovered, though, by logging into a free virtual terminal and using

loginctl unlock-session 2

where 2 happens to be the session number I have been given.

Cheers,
Juha
