--- Comment #29 from Rick <rick.avloni...@gmail.com> ---
KWin stops working when I close my laptop lid. My power options are set to "do
nothing". When I open the lid, the meta key has lost its binding.
I started my pc and opened a terninal. I entered
echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
gdb -pid $(pidof kwin_x11) -batch -ex "set logging file kwin.gdb" -ex "set
logging on" -ex "continue" -ex "thread apply all backtrace" -ex "quit"
and closed the lid. The meta key lost its binding. Then I opened another
terminal and entered
win_x11 --replace & disown
to restore functionality. Below is the stacktrace from kwin.gdb. I hope it
helps.
Thread 1 "kwin_x11" received signal SIGINT, Interrupt.
