Lion and black screens

[dav7db]

So today was the second time this happened, but basically the screen on my pro mid 2010 will randomly go off, but the computer will stay on, judging by the fans still going. Any idea what could cause this? It never happened once while on SL....

Should also be noted that to get the screen back on I have to do a forced shut down.

This has been happening to me too, and ever since I upgraded from 7.0 to 7.1. I haven't had to do force shut down though, about a min later it comes back on like it would from sleep mode.

Same here with iMac 27" from 2010; with and without ACD 24" attached. Raised ticket with Apple; they asked for some more details. So I hope they are working on it.
