Comment 9 for bug 995840

I seem to have this same problem, however, I have an issue severly compounding it. In addition to the computer locking when the lid is closed, sometimes the login screen doesn't appear. All I have is a blank screen of my desktop. I haven't found a way to fix this or get around it yet. Except for a hard reboot. Although I haven't really tried pressing Ctrl+Alt+F1 and killing/messing with things.

I just did an upgrade from 11.10 to 12.04 about 24 hours ago. I tried unlocking everything and hopefully that will be a quick fix for my problems. But, having about a 50% chance of having to reboot the system eveytime the lid is closed is pretty bad. I am not sure if this should be posted on a different or new bug report, but as it seemed related I figured I should start by posting it here.
