As root in tty3 I attached GDB to kwin_wayland and as soon I got back
to
the graphical session, the system got stuck and I could not neither
return back to tty3, so I had to use Magic SysRq key to restart the
system.
The wiki says to try to use SSH, but it would be useless too since I am
not able to use the graphical session if kwin_wayland is attached to
GDB
Of course you need to continue once you attached gdb. I'm not sure what
you want to achieve but debugging the running display manager on the
same system - well it's even more impossible than debugging the running
window manager on X11. I'm working with nested kwin_wayland running in
gdb to do debugging.
