[Pkg-xfce-devel] Bug#728361: Bug#728361: xfce4: Nor working restart/shutdown buttons

[Louis Delmas]

I have experienced the same troubles with mounting drives, using 
shutdown/restart etc... since lightdm upgrade to 1.8.

I have found that keeping libpam-systemd installed and running

pam-auth-update --force

then selecting only "Unix Authentication" solves the problem.

The previous solutions (removing libpam-systemd or commenting a line in 
/etc/pam.d/common-session) also worked but created some troubles with 
libGL (also authentication problems).

I hope it helps
