Comment 12 for bug 1760104

I had some luck with this not pausing/blinking gnome-shell:

$ sudo udevadm control --reload-rules
$ sudo udevadm trigger --subsystem-nomatch=input
$ sudo udevadm trigger --property-match=ID_INPUT_JOYSTICK=1

Alan, perhaps you can upgrade to core from edge (since it does some things with ID_INPUT_JOYSTICK) see if you can crash your system by doing:

$ for i in `seq 1 100` ; do sudo udevadm control --reload-rules ; sudo udevadm trigger ; done

If you can, please see if this doesn't crash it:

$ for i in `seq 1 100` ; do sudo udevadm control --reload-rules ; sudo udevadm trigger --subsystem-nomatch=input ; sudo udevadm trigger --property-match=ID_INPUT_JOYSTICK=1 ; done

If that works, I'll give some thought to updating the udev backend to only call 'sudo udevadm trigger --subsystem-match=input' when absolutely needed (eg, when install mir, X or wayland snaps).
