##Re: when idle
After the display has been idle, and screen timeout occurs after a while (not exactly sure cuz it happens while I was asleep), the GPU "resets" and display us unable to recover.
To reproduce: I set the display timeout to 10 min (sleep is disabled). Anything close to that, and I can still recover the display.
If left unattended for longer, the display is unable to recover.
