I'm setting up a minimalistic ubuntu based system with openbox as a window manager. Unlike the more full functioned window managers, there's no single click shutdown option. While i can shutdown using cli - this needs me to use sudo, and well, this isn't what i want. Is there any way to make the halt or poweroff commands work for any user, without the need for a password?

Run visudo and add %users ALL=(ALL) NOPASSWD: /sbin/poweroff, /sbin/reboot

So you can run sudo poweroff or sudo reboot without enter the user password.

You can configure ACPI to trigger a shutdown when the power button is pressed. In Ubuntu this is the default behavior if nothing else is running that handles the power management. Have a look at /etc/acpi/powerbtn.sh.
