Ubuntu: How to shut down my computer?



Question:

I can't find a dialogue anywhere on the desktop (like on Windows Start/shutdown) to shut down Ubuntu. I downloaded and ran the Ubuntu live CD and after I ran it, I couldn't shut it down. I had to hold the on/off key on my computer for 4 seconds to shut down my computer to get back into Windows. If there is a button somewhere, why is it not obvious?


Solution:1

Go to the upper right corner and use the gear menu to select Shut Down.

Solution:2

You can also momentarily press the power button, and a pop up dialog will appear with buttons for suspend, hibernate, restart and shutdown.


Solution:3

Here are 3 ways:

  1. You can type Ctl+Alt+T to bring up the Terminal. Then you can type either halt, or shutdown. With the shutdown command you need to specify a time. If you type shutdown 1, it will shutdown in one minute, if you type shutdown 5 it will wait 5 minutes and so on.
  2. The final option I know of is to add a keyboard shortcut by going to the top right corner and entering the System Settings>Keyboard>Shortcuts, then you'll click on the Custom Shortcuts text and click the + icon to add a custom shortcut. Just type in Shutdown or whatever you wish for the name. In the command dialog box type: /usr/lib/indicator-session/gtk-logout-helper -s and click save. Now you'll need to click where it says disabled, and you'll see the text change from disabled to New Shortcut. Now type a key command like Ctrl+Alt+End and save it.
  3. Or as the others have pointed out, you can use the power button.


Solution:4

You have to log in first. Press Esc, then log in, following that shut down via the top right corner.

I believe it's intended to keep unauthorized users from getting into the bios settings easily.
