Bug#736880: gdm3 does not work in Gnome Flashback mode

[Svante Signell]

Package: gdm3
Version: 3.8.4-6
Severity: grave

gdm3 does not work in Gnome Flashback mode, this is the fourth computer
showing the problem, forcing me to switch to xfce :( After logging in I
have icewaesel present in all workspaces, and iconizing it fails, the
screen is filled with lines indicating a movement of the full-screen
icewasel to iconized status, but the window stays (showing the
transition which never completes.

The problem is related to systemd, see below, row 4! I don't use systemd for
boot (and never will unless forced). Converting this box to xfce too
after submitting this bug report.
