--- Comment #3 from Michael D <nortex...@gmail.com> --- Sorry, but I'm not sure how to get a backtrace. I tried following https://community.kde.org/KWin/Debugging by entering the following commands in this order: echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope gdb --pid `pidof kwin_wayland` 2>&1 | tee kwin.gdb and it crashed the session. Worse, I can't login anymore to wayland anymore---I just get a black screen (though if I push the power button, it shuts down properly). Attached is the kwin.gdb file. -- You are receiving this mail because: You are watching all bug changes.
