This is happening to me as well, it started 2/3 months ago but as I was using my computer less I didn't really notice when exactly. I'm using 13.10..
Switching tty back and forth won't help. I've tried various dbus command to stop the lockscreen but with no luck so far. Anything I can do to help, let me know, as it seems to be pretty easy to reproduce with my computer. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1181237 Title: Kubuntu 13.04: System Frozen when Resuming from Suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/1181237/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
