I know similar questions have been asked, but I can't seem to locate and answer... so I thought I would take a stab.
However I attempt to shutdown, poweroff or restart, Ubuntu hangs on the red Ubuntu screen (with the 4 dots - the first one lights up) and it stays there.
I left it one last night and it was still there this morning. Is this a bug? Is there a fix? Will 12.10 resolve this?
It is obvious I am not the only one dealing with it.
