Public bug reported:
Following https://wiki.ubuntu.com/X/Quirks#Force_Pipe_A_Quirk I can
confirm that the following hardware is affected by a blank screen after
lid closing and reopening.
Laptop: Lenovo 120s 11IAP
$ lspci -vvnn | grep -A1 "VGA compat"
00:02.0 VGA compatible controller [0300]: Intel Corporation Device [8086:5a85]
(rev 0b) (prog-if 00 [VGA controller])
Subsystem: Lenovo Device [17aa:39fd]
I can confirm that adding "ForceEnablePipeA" solves the problem.
