After I installed ubuntu 11.04, it wont shutdown nor restart, it just freeze, and I have to hold the power button in order to turn off my netbook. (It also happens on livecd)
Can anyone tell me the solution for this?
This is a bug related with wireless driver. This bug has been reported in launchpad. Asolution is mentioned in ubuntuforums post here http://ubuntuforums.org/showthread.php?p=10796364#post10796364

To restart the PC :

I noticed that when you do some stuff like mounting drives (as root) and you try to turn your PC off from a regular user, you are not allowed. Which is good in terms of security for a Server, but too secure for a Home PC.
