The attached captured image shows a message that pops up after the display has turned black for about one or 2 two seconds.
It has been occurring quite a few times recently when watching some youtube video clips. The screen goes black every 5 or 10 sec. for about 1 or 2, then it recovers on its own and the above message is shown at the tray.
I have no idea what's going on and why. Does it mean I do not have the correct drivers installed?
