+[[!meta title="On X session logout, the X server does not exit"]]
+
+This is due to a missing implementation of a corner case of Posix signaling for non-root processes to root processes.
+
+One can however use the usual ctrl-alt-backspace shortcut to kill the X server.
+
+You just need to configure it via the file:
+`/etc/X11/xorg.conf.d/xorg-ctrl-backspace.conf`
+
+ Section "InputDevice"
+ Identifier "Generic KeyBoard"
+ Driver "kbd"
+ Option "XkbOptions" "terminate:ctrl_alt_bksp"
