Xubuntu hotkey for immediate shutdown

I would like to create a two hotkeys. First for terminating all procesess and shutdown the system and turn computer off.

I have tried something but it only logged me off and then I had to confirm I want to log off and then turn off computer manually.

The second one for simple log off.

What is the command I should type in keyboard/hotkey settings? Or should I make .sh file and run it? What command for running the file should I use then?

Thank you very much!

gksudo shutdown -h now would come to mind, but this command requires root privileges. To execute it you would have to enter you password.

Here's a command that should work without root and shut down your PC immediately (compatible with all official Ubuntu flavors):

dbus-send --system --print-reply --dest=org.freedesktop.ConsoleKit /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Stop

These are Xubuntu-specific:

• shutdown: xfce4-session-logout --halt


• restart: xfce4-session-logout --reboot


• log out: xfce4-session-logout --logout


• suspend: xfce4-session-logout --suspend


• hibernate: xfce4-session-logout --hibernate
