How do I shut down without the confirmation prompt?

Are you sure you want to close all programs and shut down the computer?

When I click shut down I want to shut down! :) This message bugs me. How to avoid this message?

Solution 1:

11.04 and previous versions of ubuntu

• Alt + F2 and enter this: gconf-editor
  
• apps > indicator-session
• select suppress_logout_restart_shutdown

OR

• Alt + F2 and enter this:
  

gconftool-2 --type bool --set /apps/indicator-session/suppress_logout_restart_shutdown true

To re-enable confirmation, replace the keyword true with false

Solution 2:

For 12.04 an later

Settings for the indicator session and logout menu are found by running dconf-editor (from dconf-tools )

Solution 3:

• press Alt+F2 and type gconf-editor
• go to /apps/indicator-session and check items you want
