    lightdm - Login/Logout Broken

    Hi Guys,

    Did a release upgrade from 13.04 to 13.10 and have the same problem on two machines. Release upgrade went without any incident, no errors, no warnings, apparently all successful.


    Q: First off, why doesnt "stop lightdm" from the shell prompt work anymore? I could often halt lightdm via start/stop lightdm (to bring down X (for the purposes of installing nvidia driver)). I now have to use the script in init.d to bring down lightdm, other wise i get a "lightdm: unknown instance" error. I notice some systemd messages in the startup, has something changed with the way services start and are controlled (those referenced under /etc/init)? I notice there is no systemctl command anyway.

    Q: The options to reboot/shutdown/suspend at the lightdm logon screen are greyed out - WHY Similarly if I try and shutdown once logged into KDE, rather than shutting down the machine, it just logs me out of my current kde session and kicks me back to the lightdm logon screen

    Q: No network manager applet on my laptop after upgrade.Could not manage any connections, manually added the applet. Ethernet connection works, i can see a list of wireless networks but cannot join (putting in password and clicking "connect" does nothing", similarly, adding a "new connection" in the network manager does not save the connection at all, list is empty.

    I tried nuking the .kde directory under my home dir in case it was a corrupt profile. Made no difference. I suspect it is a permission issue or some issue with polkit?

    Any advice?

    Just curious, why do you need to bring down X to install the nvidia driver? I can't remember ever having an issue with installing any Nvidia drivers (although I always use the Synaptic package manager).

      Because I install the version off the NVidia site, it's usually somewhat more recent than versions in the apt repositories. The installer is an ncurses based installer. The installer will usually fail if X is running

        seems this was my fault. i did a fresh install and noticed all the problems were gone.. So I put it down to a bad upgrade... I then introduced my custom kernel and all the problems came back...

        I noticed some "systemd-login" errors too.. For some reason turning on the the following options in the kernel and matching those set in generic seemed to fix the issue:

        Automatic process group scheduling (was off, set to ON)
        Control Group support (all off, set to ON to match generic kernel setup)
        Namespace support (matched generic kernel settings, they were all off in mine for some reason)!

        Did a kernel rebuild, all the problems seem to have gone, and i can stop/start lightdm the usual way again. Wonder what changed between 13.04 and 13.10.... My custom kernel worked fine until this release, anyway I am glad it's sorted
