I have the same issue. I seem to be able to pretty consistently cause this to happen by opening a google chrome window and then going to a few websites. It crashes KDE/Plasma The toolbar above each window disappears and the windows can no longer be moved or resized, but I can still move the mouse and mostly interact with window/programs already opened. I wonder if it's crashing on going from the integrated i915 to the Nvidia gpu?

With further testing - I can get the crash to happen with other applications, not just chrome. I ran nvidia-settings and changed from "NVIDIA (Performance Mode)" to "Intel (Power Saving Mode)" and it makes no difference in the crash reproducibility. I can get a x crash 100% of the time with the following procedure 1. Run glxgears 2. Click the X (close) in the glxgears window menubar 3. Crash: What happens 3a) menu bar on all each open window disappears 3b) windows cannot be moved or resized - but can still be clicked in and interacted with: example 3c) taskbar icons representing windows frozen but you can still click and interact with the K-start-icon Sample Output (this is running with the Intel i915 power saving driver): ------------- $ glxgears Running synchronized to the vertical refresh.

Possible Duplicates by Search: bug 352548, bug 353624 ----- After crash - in terminal window I get $ qdbus org.kde.KWin /KWin supportInformation | grep Plugin Service 'org.kde.KWin' does not exist. ------------ I can get things working again with the following command $ DISPLAY=:0 kwin --replace And then in a terminal window I get $ qdbus org.kde.KWin /KWin supportInformation | grep Plugin Plugin: org.kde.kwin.aurorae
Running glxgears again (having run kwin_x11 --replace in terminal window) results in the following error in the terminal window where I ran the kwin_x11 command ------------------ Application::crashHandler() called with signal 11; recent crashes: 1 KCrash: crashing... crashRecursionCounter = 2 KCrash: Application Name = kwin_x11 path = /usr/bin pid = 3069 KCrash: Arguments: /usr/bin/kwin_x11 --replace KCrash: Attempting to start /usr/lib/x86_64-linux-gnu/libexec/drkonqi from kdeinit sock_file=/run/user/1000/kdeinit5__0 kwin: unable to claim manager selection, another wm running?

Switching to breeze for "Widget Style and Behavior" solves my problem. $ qdbus org.kde.KWin /KWin supportInformation | grep Plugin Plugin: org.kde.breeze I can run glxgears and close it without crashing kwin. Sur006327, does that solve your problem too?
Hello! This bug report was filed for KDE Plasma 4, which reached end-of-support status in August 2015. KDE Plasma 5's desktop shell has been almost completely rewritten for better performance and usability, so it is likely that this bug has already been resolved in Plasma 5. Accordingly, we hope you understand why we must close this bug report. If the issue described here is still present in KDE Plasma 5.12 or later, please feel free to open a new ticket in the "plasmashell" product after reading https://community.kde.org/Get_Involved/Bug_Reporting If you would like to get involved in KDE's bug triaging effort so that future mass bug closes like this are less likely, please read https://community.kde.org/Get_Involved#Bug_Triaging Thanks for your understanding!
