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...

System worked without any problems under 14.04 2. Upgrade to 14.10 3. Upgrade went without any problems 4. Notice that standby has disappeared from the "gears" menu 5. notice that I cannot disconnect or change the network connection (exact error is: "(32) Not authorized to control networking.") 6. I can't see, change or unlock setting under Settings > User accounts 7. Running "dbus-send --system --print-reply --dest=org.freedesktop.ConsoleKit /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Stop" from the terminal results in the error: "Error org.freedesktop.ConsoleKit.Manager.NotPrivileged: Not Authorized" 8. Running "sudo pam-auth-update --force" doesn't solve any errors 9. Creating a new user account (sudo adduser) and switching to the account results in the same permission problems. Sudo works as expected so I can help to further debug this problem and provide relevant information. Unfortunately I have very limited experience with ConsoleKit and PAM so I hope I have reported this to the right package. If someone could point me in the right direction (wiki, man page, tutorial) I would be more than happy to see if I can see what went wrong and if I can debug this myself.
