I've activated kubuntu-backports and I'm now running a fully updated system (KDE 5.3). The problem still persists. I don't get the login screen if I turn off the monitor and then immediately on again. However, if I turn off the monitor when I go to bed and then turn on it again in the morning, my session is killed and I get the login screen. So, the crash actually happens when you turn on the monitor, not when you turn it off.
Please let me know what more information is required to troubleshoot this. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kubuntu-meta in Ubuntu. https://bugs.launchpad.net/bugs/1492778 Title: kde crashes when turning powering on display port monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kubuntu-meta/+bug/1492778/+subscriptions -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
