After resuming from Suspend PlasmaShell is nonresponsive. Reproducible: Sometimes Steps to Reproduce: 1. Suspend. 2. Resume Actual Results: 1. First sign of trouble: No Compositing Effects 2. Minimally Functional Panel: Can hover over Task Manger and see drop down windows, but clicking on windows doesn't "activate" application. 3. Application Launcher drops down but attempting to launch any application fails. System is unusable. Have attempted to restart plasmashell: killall plasmashell && kstart plasmashell But results in same issues -- and no compositor. Tried switching to OpenGL 2 with disastrous results. I'll attach an image. Currently using open GL 3.1 with GLX Interface and Full Screen Repaints (tearing). Didn't have these issues with 15.04 or 15.10. They all started after upgrading to 16.04, so maybe this is a BETA issue?

More information: Finally getting error messages: "Desktop effects were restrarted due to a graphics reset." Further error messages when resuming from suspend: There seems to be a problem with "klockscreen"? (Getting above my pay grade here.) When attempting to report the bug a dialog window prompted that the following packages were obsolete and the bug could not be reported. (Don't know if this is all related.) gcc-5-base, libstdc++6
Speak of the devil. Just checked upgradable and both packages were updated. Stay tuned.
I can confirm the same thing happen on my platform. Running Kubuntu 16.04. I find the following error when I start plasmashell, it may be related or not. file:///usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Controls/Button.qml:96: TypeError: Cannot read property of null file:///usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Controls/Button.qml:96: TypeError: Cannot read property of null file:///usr/share/plasma/plasmoids/org.kde.plasma.systemtray/contents/ui/TaskDelegate.qml:156: TypeError: Cannot read property 'taskItem' of undefined
PGillespie can you report back plase? Olav, that output isn't going to cause a problem. When you had this issue did you still have window decorations (the bar with the minimize and close buttons) visible on your apps? Was there a crash icon in the system tray?
Hi David, this was over a year ago. Now I'm on Kubuntu 17.04 and I just right now tried to suspend on my workstation. Everything worked fine! :-)
Ok, thanks for reporting back.
