I believe I found a not too difficult workaround to the common shutdown/restart hang many users of Kubuntu 11.10 have been experiencing. First set up a new user account. After that, right click on your mouse and there will be a 'leave' option along with several others; click on leave. A menu will pop up offering several shut down options, choose 'log out'. This should, after a delay get you back to your password screen. In the lower right corner is another red leave circle, click on this. Once again you will be offered shut down options. Click whichever you desire and it should work.
This doesn't work with any of the other leave buttons, neither in the new activities dropdown menu nor the leave button in the start menu. Now I don't know that this will work with every hardware configuration, or every system installation. You'll just have to try, There doesn't appear to be any general consensus, among the forums I've surfed, about what the cause of this bug is. Also, I know this fix is a little cumbersome, but it does have the advantage of being a mouse only technique, which I find a little easier than switching to the konsole and typing in a sudo and verifying with a password. Being of the trash 88 and earlier school of computer use, it bothers me to do a hard reboot everytime I want to reboot or shutdown. Hope this helps.
