Every time I suspend the notebook (close lid, not sure about suspension
by command) when I unsuspend (open lid) a long time black screen with
only mouse pointer visible delays the login screen to display (about
10~15 seconds of delaying). The mouse pointer works but with brief
freezings when moving, something like 0,5s of freezing for each 1,5s
moving.
This notebook is a i7 16GB ram 120GB SSD so it should never happen, in
fact, it never happened in Deepin Linux or even Ubuntu 16.04.
I will be available to provide some other information you need.
Thanks.
