Hi, To answer your questions : 1/ julien@pcathlon64:~$ aptitude search libpam-systemd i libpam-systemd - system and service manager - PAM module i libpam-systemd:i386 - system and service manager - PAM module (I tried to reinstall it, does not fix the problem)
2/ administrateur@pcathlon64:~$ sudo start systemd-logind [sudo] password for administrateur: systemd-logind stop/pre-start, process 4754 And when I do then ps aux|grep 4754, no process is returned. In my syslog, I get the following message : Mar 27 08:08:09 pcathlon64 dbus[1280]: [system] Activating service name='org.freedesktop.login1' (using servicehelper) Mar 27 08:08:09 pcathlon64 dbus[1280]: [system] Activated service 'org.freedesktop.login1' failed: Cannot launch daemon, file not found or permissions invalid OK I've found the issue : 1/ remove libpam-systemd:i386 and libsystemd-login0:i386 Now everything should be fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1295521 Title: cannot shutdown/suspend/restart from the GUI To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm/+bug/1295521/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
