Hi.
I am having problem with my laptop - Samsung Q210.
Sometimes - usually after long time lid closed - it happen what in subject.
It is set not to go suspend or hiberate as it is doing something which takes time.
I do not want to break system as it is fine after killing xorg or restarting whole Mint.

Can anybody help?
