I managed to fix this bug by removing upstart. When I reinstall it the bug comes back.
I know it's not a decent solution but I hope it helps you guys debug this issue. I'm of course willing to do further debugging work. This 7 page topic on the Ubuntu forums seems to have lots of users with the same problem: http://ubuntuforums.org/showthread.php?t=2246405 As far as I can see I only have the amd64 version of libpam-systemd installed. Synaptics list these files as installed for the package libpam-systemd : /. /lib /lib/x86_64-linux-gnu /lib/x86_64-linux-gnu/security /lib/x86_64-linux-gnu/security/pam_systemd.so /usr /usr/share /usr/share/doc /usr/share/doc/libpam-systemd /usr/share/doc/libpam-systemd/changelog.Debian.gz /usr/share/doc/libpam-systemd/copyright /usr/share/man /usr/share/man/man8 /usr/share/man/man8/pam_systemd.8.gz /usr/share/pam-configs /usr/share/pam-configs/systemd Just to be sure I ran: sudo apt-get remove libpam-systemd:i386 and libsystemd-login0:i386 sudo apt-get remove libpam-modules:i386 libpam-cap:i386 The output was as following: laurens@laurens-desktop:~$ sudo apt-get remove libpam-systemd:i386 and libsystemd-login0:i386 Pakketlijsten worden ingelezen...
