I started using pm-suspend after this advice, and indeed it haven't
happened until today (2 weeks). I tried to suspend it again (and
bring back) with various pm-suspend quirks, but nothing helped - I just
rebooted to get my screen back. I understand that the using of quirks
may not help if it already failed and fell into a bad mode. But
anyway, does anybody use those quirks with Intel GM965 card?
