Bug Description
This has now happened multiple times. When I just lock my screen (I have one external monitor attached to my laptop via HDMI) and leave my laptop alone for a while, it has somehow frozen when I get back. I'm not sure how long it will take, but something like 30-60 mins perhaps. Either one or usually both screens are just black and the machine doesn't respond to mouse or anything (haven't tried to SSH to the laptop).
If I just suspend the laptop everything always goes just fine and it always wakes up.
