--- Comment #4 from Peter Hutterer <peter.hutterer at who-t.net> ---
Post the top of libinput-debug-events --verbose please, that should show if
libinput pairs the switch correctly. The obvious question too: are you typing
or using the touchpad?

this cannot work. libinput relies on other devices (keyboard, touchpad) to send
events and thus signal that the lid is open. If you init libinput this way, it
only listens to the lid device, so it can never detect any input that would
trigger the write open. See

explanation
