609	"""Dim Display"" power setting + VirtualBox inactivity = system hangs"	dacha	kris	"I have PC-BSD 9 running on VirtualBox 4.1.2_Ubuntu r38459 on an Ubuntu 11.10 host, with the VirtualBox guest additions.

After being inactive for some time (about 10 minutes), CPU usage jumps to 100% and stays there, and all SSH sessions into my PC-BSD system freeze (input and output), so it looks like a system-wide problem. But when I move the mouse over the PC-BSD VirtualBox window, the CPU usage comes down, and the SSH sessions work again.

I've also figured out how to work around this problem. If I start ""PC-BSD control panel"", then go to ""System Settings"", click ""Power Management"", select the ""Power Profiles"" tab on the left, and uncheck the ""Dim Display"" checkbox (which is checked by default), then it no longer happens.
