Hi Colin and all the others, I recently upgraded a laptop and I also sometimes had the 'can not shutdown/reboot' probleem.
If what Colin mentions is true, then would it not help to just disable the getting the recently-logged-in-user-list from consolekit as a test/workaround ? Which can be achieved with the following command. sudo -u gdm -- gconftool -s /apps/gdm/simple-greeter/disable_user_list true --type bool which changes the file: /var/lib/gdm/.gconf/apps/gdm/simple- greeter/%gconf.xml I enabled the debug in /etc/gdm/gdm.schemas before hand by setting the 'debug/Enable' to true and judging by the /var/log/gdm/:0-greeter.log file it seems it doesn't talk to consolekit anymore at startup. Normally it would say something like this: GdmUserManager: Found current seat: /org/freedesktop/ConsoleKit/Seat1 But not with the recent-user-list-disabled. Maybe someone like Damien can test this ? Because I can't really reproduce the problem very well. Possible you could also post (part of) a logfile of when it fails to work, maybe there is an other hint in there as well. I hope this helps, because this is a pretty annoying problem. -- Active VT tracking can fail at startup https://bugs.launchpad.net/bugs/544139 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
