Public bug reported:
Ubuntu is supposed to suspend on lid close.
After fresh restart, nothing happens on lid close / open. But once the
native-screen brightness has been changed, the system freezes on lid close
(power-cycle needed).
However, suspend option from Ubuntu notification menu works flawlessly in all
cases.
Laptop: Lenovo Thinkpad W530 with Discrete Graphics (selected in BIOS)
and NVIDIA driver 381.22.
