I have an older hp pavilion all in one pc and after upgrading to 15.04 whenever I tell the computer to shutdown while in unity (haven't tried other DEs) it goes to the login screen as if I'd only pressed logout. It will then shutdown if I select shutdown from the menu in lightdm. But why is it doing this?

  • After attempting to do this does anything relevant appear in `/var/log/syslog` such as an error about unable to shutdown? – thomasrutter May 26 '15 at 00:46

  • I think that purging and reinstalling `lightdm` might help you out. – TheWanderer May 26 '15 at 00:51
  • I checked syslog in a terminal straight after it logged out and there is no error about not being able to shut down. – Martin Croft May 26 '15 at 06:55
  • If `sudo shutdown -P now ` works make it a script or run manually till you resolve the issue. Personally that's what I do 99% of the time. I'm guessing there's an issue with dbus since that's what unity uses, if I'm not mistaken – Sergiy Kolodyazhnyy Aug 02 '15 at 05:05
  • Or better yet bind the command to a keyboard shortcut. I'll find a link to another script I've used before and post if you're interested – Sergiy Kolodyazhnyy Aug 02 '15 at 05:07

If you have docky installed this fixed the problem for both of my machines.

Ubuntu 15.04 Unity + Docky, Cairo-Dock, or Plank

(DOCKY)

cd ~/.config/autostart
nano docky.desktop
add X-GNOME-Autostart-Delay=20

(IF YOU USE CAIRODOCK)

cd ~/.config/autostart
nano cairo-dock.desktop
add X-GNOME-Autostart-Delay=20

Or you can remove either one from autostart.

Example docky.desktop in ~/.config/autostart with 20 second delay

[Desktop Entry]
Type=Application
Exec=docky
Hidden=false
NoDisplay=false
X-GNOME-Autostart-Delay=20
X-GNOME-Autostart-enabled=true
Name[en_US]=Docky
