Created attachment 123169 [details] gdb trace of when it hangs. SUMMARY Hanging of plasmashell. It seems related to an external monitor on a laptop. STEPS TO REPRODUCE 1. restart the computer, with two screen 2. Wait and see plasmashell eating 100% of the CPU while not showing up. EXPECTED RESULT Some plasmashell features, such as the taskbar, should appear. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Archlinux (available in About System) KDE Plasma Version: 5.16.5-1 The gdb trace is attached to this ticket.
Would that be possible to change this bug report importance to "crash". I don't seem to have access to that.
That isn't a gdb trace. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
I am not sure to understand what do you mean. I was using the repository packages. The trace were provided by running "gdb plasmashell" then a series of "continues" with "thread apply all backtrace". So it helps to know where it hangs/stalls.
A lot of stuff with #0 0x00007fffd08f52f1 in ?? () from /usr/lib/qt/qml/org/kde/private/desktopcontainment/folder/libfolderplugin.so Is this still reproducible for you? If so, please install debug symbols for plasma and get a new trace so we can see where exactly it's stuck. Thanks!
