I have installed Xubuntu 11.10 on a Compaq Presario P4. I am using it headlessly, to serve files. So the way I can turn off the box is by pressing the power button once. But it refuses to do it. Any advice?
I have configured in the SETTINGS MANAGER => POWER MANAGER so as to effect a shutdown on pressing the power button. I have also checked in the SETTINGS EDITOR that property "xfce4-power-manager => power-button-action" takes value of 4.
