Don't know, if this is the same bug. I'm using the final version of Kubuntu 15.04 (all published updates installed) - it's impossible to shutdown the pc properly. I get a black screen but it isn't switched off. So I have to switch it off manually and I'm scared about data on my possibly still mounted drives... Ctrl+Alt+F1 doesn't work. I think, keyboard doesn't accept anything at all (e.g. caps lock).
Hypernating is quite unstable - maybe it's related to this, maybe not, maybe this could be a hint for a systemd issue. I tried to hibernate 3 times: 1st time: didn't switch off at all - only the screen flickered and was locked afterwards 2nd time: switched off, but then switched on instantly 3rd time: switched off, but when I returned 1hr later, the computer was running, but it didn't respond. I've had none of these problems in Kubuntu 14.10 or 14.04... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1407152 Title: Can't log out from Plasma session with SDDM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-keyring/+bug/1407152/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
