#609 closed System Defect (wontfix)

"Dim Display" power setting + VirtualBox inactivity = system hangs

Reported by: dacha Owned by: kris
Priority: major Milestone:
Component: System Tool Version: 9.0-RELEASE
Keywords: Cc: trac-bugs@…


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.

Can you tell us more about the kind of hardware you are running on? Just for the sake of curiosity.

We can't disable these settings by default, but it sounds like you found the work around. We're going to go ahead and close this, but if you can duplicate the same problem in 9.1 please let us know.
