--- Comment #3 from panorain <pj.wo...@gmx.com> --- (In reply to fanzhuyifan from comment #2) > When your system freezes, could you use ctrl+alt+f3/f2 to switch to a VT No, frozen solid, no VT available that way. > (You may need to do ctrl + alt + SysRq, and R first), and check I can try, I think not possible. > > 1. Is any process using 100% of cpu? Not prior to crash and how can this be shown after crash (top/htop etc)? > 2. Attach a gdb instance to kwin, and attach the outputs of `thread apply > all backtrace full`? > Ok, trying to do this suggestion ^. > Thanks!

Then used 'tmux' on host and 'tmux a' on client (seems to work). Been reading > https://community.kde.org/Guidelines_and_HOWTOs/Debugging/Debugging_with_GDB Can you suggest a specific area to follow perhaps? :-> top | grep kwin 5163 panorain -2 0 3020188 350068 269816 S 1.982 2.143 10:13.40 kwin_wa+ :~> gdb kwin 5163 GNU gdb (GDB; openSUSE Tumbleweed) 15.2 Copyright (C) 2024 Free Software Foundation, Inc.
