I tested the ppa in comment #5, and I note the following changes. Environment is a docked laptop with 2 external displays.
When the laptop is removed from the dock (external displays disconnected), I no longer receive a segfault for plasmashell, but the panel does not automagicailly resize to the new resolution. When the external displays are reconnected, plasmashell segfaults (same as previous/xenial behavior). I think this issue is resolved in QT5.5, but not specific to this bug/patch. Atleast I don't have to restart plasma every time I dock/undock, but behavior is still less than optimal. Progress though. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1548766 Title: Plasma crashes when the monitor is disconnected (when it sleeps, in some cases) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qtbase-opensource-src/+bug/1548766/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
