</code>

===== Debugging =====

1) In the graphical session, find the value of DISPLAY and XAUTHORITY variables: echo $DISPLAY :0 echo $XAUTHORITY /run/user/…

2) SSH into the computer from another machine using the same user as in the graphical session.

3) Set the DISPLAY and XAUTHORITY variables to the same values as above: export DISPLAY=:0 export XAUTHORITY=/run/user/…

4) Start kwin in gdb in the ssh session: gdb –args kwin_x11 –replace 5) Reproduce the issue. 6) The gdb is now hopefully showing segfault, abort or something. If not, hit CTRL C to get gdb prompt. Then run the "generate-core-file": (gdb) generate-core-file
