Every time I restart or shut down my new installation of Ubuntu 12.04, I get to a black screen and the computer just hangs there forever. The only way to get past that is through the physical restart/shutdown button. When I do restart the machine that way, next time Ubuntu starts, there's no indication that a faulty shutdown occurred, everything proceeds as intended.
I would love to investigate this issue and figure out what's going on, since not being able to restart the machine remotely is a show stopper.
Are there any logs I could look into to understand this better? Any other advice?
Link to the Q87M-E motherboard, in case that helps.
