This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Have you logged into any of the virtual terminals at tty1,tty2, etc..? – saji89 Nov 26 '12 at 5:33
I was not logged into any virtual terminal. – madox2 Nov 26 '12 at 12:29

There is an issue for some users in 12.04 and 12.10 where shutdown/restart only logs them out of their user session and does not shut down the machine, and using shutdown/restart from the login screen does nothing. It is apparently just a bug. You can try some of the solutions you may be able to find in Google but nothing has worked reliably for me.

You can still shutdown your computer by opening a tty terminal (CTRL-ALT-F2 through F6), logging in as root, and entering

shutdown -h now

which will shutdown the system or


which will reboot it.

Thanks! This helps, but there is still bug in Ubuntu. Do you have this problem too? – madox2 Nov 27 '12 at 9:55
