Comment 1 for bug 138194

This just happened to me with Gutsy and KDE. I clicked "Turn Off" and closed the lid, and put my laptop in my bag--I've never had Kubuntu fail to shut down before. When I got home 20 minutes later, it had never shut down, and it was quite hot. Checking the acpid log shows that it executed the script for the lid event, and apparently shut down acpid, but the system did not shut down. The VTs were unresponsive, but I was able to use the SysRq key to make the kernel reboot.

In this log snippet, the button event was when I pressed the power button, after which I clicked "Turn Off". Then I closed the lid...
