Bug#812555: gnome-session-flashback (temporary) black screen

[Maxxie]

Package: gnome-session-flashback
Version: 3.18.1-1
Severity: important

Every time I start a gnome flashback session it just shows me a black screen
and the mouse which can't be moved. After waiting a couple of minutes the
session starts and it works perfectly until the logout. While the screen is
black I'm able to ssh to my computer and even start graphical programs in it
(tried gedit). Switching user does not trigger the problem, nor does standby.
Other gnome sessions work flawlessly.
