How often does this crash occur? Can you reproduce it reliably?
Not sure whether this is related: Kwin crashes every time I wake from suspend if the monitor is powered down when the system wakes. This is a replicable bug on my system. The crash only occurs when I manually power down the monitor after suspend (which is necessary in my case), then attempt to wake from sleep *before* powering the monitor back up. If I power up the monitor before wake, the bug does not occur. Crash text simply says: `Application: KWin (kwin_x11), signal: Segmentation fault` Furthermore, when clicking the button on the bug report app to install missing symbols for the backtrace, the process fails with an error stating the packages cannot be installed. No additional information is presented, nor does it say what the missing packages are. Clicking the link below that bug report dialog to list missing debug packages (with a view to installing manually) just lists the following: `/usr/bin/kwin_x11`. The monitor is attached through DisplayPort. Journald provides the following related log entries: ``` Mar 11 12:09:29 aninstanceofubuntu kernel: kuiserver5[3455]: segfault at c ip 00007fb21507f60b sp 00007ffedc47e010 error 4 in libQt5XcbQpa.so.5.9.5[7fb215044000+fe000] Mar 11 12:09:29 aninstanceofubuntu kernel: nextcloud[2560]: segfault at c ip 00007f9b9825460b sp 00007ffdf30070b0 error 4 in libQt5XcbQpa.so.5.9.5[7f9b98219000+fe000] Mar 11 12:09:29 aninstanceofubuntu kernel: kwalletd5[2333]: segfault at c ip 00007fe7af82660b sp 00007ffcb49751e0 error 4 in libQt5XcbQpa.so.5.9.5[7fe7af7eb000+fe000] Mar 11 12:09:29 aninstanceofubuntu kernel: kdeconnectd[2516]: segfault at c ip 00007f6877d8660b sp 00007ffda4bfe5c0 error 4 in libQt5XcbQpa.so.5.9.5[7f6877d4b000+fe000] Mar 11 12:09:29 aninstanceofubuntu kernel: kactivitymanage[2462]: segfault at c ip 00007fee76fd360b sp 00007fff0eff7300 error 4 in libQt5XcbQpa.so.5.9.5[7fee76f98000+fe000] Mar 11 12:09:29 aninstanceofubuntu kernel: xembedsniproxy[2508]: segfault at c ip 00007f3db9a2e60b sp 00007ffe71020820 error 4 in libQt5XcbQpa.so.5.9.5[7f3db99f3000+fe000] Mar 11 12:09:29 aninstanceofubuntu kernel: baloorunner[3521]: segfault at c ip 00007f3be7a5960b sp 00007ffc1f7bf180 error 4 in libQt5XcbQpa.so.5.9.5[7f3be7a1e000+fe000] Mar 11 12:09:29 aninstanceofubuntu kernel: kscreen_backend[2531]: segfault at c ip 00007fcf211da60b sp 00007ffddeb4eb40 error 4 in libQt5XcbQpa.so.5.9.5[7fcf2119f000+fe000] ``` System info: - Kubuntu 18.04, with Kubuntu backports PPA (kubuntu-ppa-ubuntu-backports-bionic) - KDE Plasma Version: 5.12.9 - KDE Frameworks Version: 5.47.0 - QT Version: 5.9.5 - Kernel Version: 5.3.0-40-generic - CPU: 4 x AMD Ryzen 3 3200G with Radeon Vega Graphics (onboard) - Memory: 29.4 GiB DDR4 RAM
