[Pkg-xfce-devel] Bug#760940: xfce4-session: No shutdown / reboot with SLiM anymore

[Christopher Schramm]

Package: xfce4-session
Version: 4.10.1-8
Severity: normal

Starting with xfce4-session 4.10.1-7 I'm having trouble with shutdown and reboot in conjunction with SLiM. When I try to shut down or reboot the system using Xfce's dialog, the desktop disappears as usual, but then SLiM shows "failed to execute login command" and I end up at the login screen. It somehow fails to shut down the X server. I can initialize a shutdown from the login screen by pressing the power button then.

SLiM is configured to grab the sessions from /usr/share/xsessions, so the only command it seems to know is startxfce4. I'm seeing this on two different systems.

None of the documented changes of 4.10.1-7 seems to possibly cause this, but I can replicate and "fix" it just by switching between xfce4-session 4.10.1-7 and 4.10.1-6. Any ideas?
