(cherry picked from commit 13fb70fec16efca4f54788cd9c87c8ece4700d03) M +3 -0 shell/shellcorona.cpp https://invent.kde.org/plasma/plasma-workspace/commit/7956d7b2e18133b92ec5d6cab674b1390daac9b8 I can't reproduce this crash. Can you confirm that this issue is still present? I'm unable to test on neon unstable. Plasma always starts with mult-monitor mode set to "Switch to laptop screen". And kded5 crashes when I try to start Plasma with a different multi-monitor mode. #0 __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:50 #1 0x00007f58758a7859 in __GI_abort () at abort.c:79 #2 0x00007f5875d03bd7 in qt_message_fatal (context=..., message=<synthetic pointer>...) at global/qlogging.cpp:1914 #3 QMessageLogger::fatal (this=this@entry=0x7ffcf16f1170, msg=msg@entry=0x7f58769ea8c5 "%s") at global/qlogging.cpp:893 #4 0x00007f5876531a53 in init_platform (argv=<optimized out>, argc=@0x7ffcf16f142c: 12, platformThemeName=..., platformPluginPath=..., pluginNamesWithArguments=...) at ../../include/QtCore/../../src/corelib/tools/qarraydata.h:208 #5 QGuiApplicationPrivate::createPlatformIntegration (this=0x561a97a172d0) at kernel/qguiapplication.cpp:1481 #6 0x00007f5876531ee8 in QGuiApplicationPrivate::createEventDispatcher (this=<optimized out>) at kernel/qguiapplication.cpp:1498 #7 0x00007f5875f2cab6 in QCoreApplicationPrivate::init (this=this@entry=0x561a97a172d0) at kernel/qcoreapplication.cpp:853 #8 0x00007f5876535003 in QGuiApplicationPrivate::init (this=this@entry=0x561a97a172d0) at kernel/qguiapplication.cpp:1527 #9 0x00007f5876c3811d in QApplicationPrivate::init (this=0x561a97a172d0) at kernel/qapplication.cpp:513 #10 0x0000561a95c7ec15 in main (argc=<optimized out>, argv=0x7ffcf16f16d8) at ./src/main.cpp:100 > Plasma always starts with multi-monitor mode set to "Switch to laptop screen".
Can confirm that. Is there another bug report about it?
(In reply to Nate Graham from comment #19) > > Plasma always starts with multi-monitor mode set to "Switch to laptop screen". > Can confirm that. Is there another bug report about it? I haven't seen any so far. should not be this ticket set as confirmed? moving to confirmed Patrick, can you still reproduce this in current git master? There have been a lot of multi-screen Wayland fixes recently. Plasma is no longer crashing after the provided steps, but plasmasession is. Reported as bug 454159. We have a very similar issue happening where apps and Plasma crash in QtWaylandClient::QWaylandWindow::handleScreensChanged() when monitors enter power save mode. See Bug 473020, Bug 468846, and Bug 467147. I can't tell whether they're the exact same issue, or slightly different. |
