I upgraded to 4.4.3 from 4.4.2 this morning from AlienBob's packages (although I see they are now part of -current, but the mirrors are still behind) and I can no longer return from suspend on my laptop. I get a black screen with a mouse pointer that moves freely but it does not bring up my desktop. Ctrl-Alt-Backspace will bring me back to the console as it should, but this is a huge step backward. A few times I got a message about a new screen being detected after resuming but now it's just blank. I am running an intel onboard graphics card on an Asus laptop.
