Force Restart on CTRL+ALT+DEL on XFCE


I've hired a dedicated Ubuntu10.10 Server on a remote colocation. I needed a GUI to be able to hook into my KVM guests, so I installed xubuntu-desktop.

My dedicated server provider provides me very useful free service. I can request a CTRL+ALT+DEL to my server through their web based server control panel, and I can boot into a live image from their network. This is vital for me to be able fix back configuration problems.

However after I have installed xubuntu-desktop (XFCE I believe), the CTRL+ALT+DEL no longer reboots the machine.

I've been struggling with this simple issue for quite a few days, I simply can't get it to work.

I've tried setting it through XCFE 4 Settings Manager. It does not work. From my understanding any keyboard shortcuts defined here are specific to user, so I think they'll not work when the server is in login screen (no user logged in).

I've tried to put control-alt-delete.conf files in /etc/init and /etc/event.d/ , neither seems to trigger reboot. Documentary propose /etc/event.d has been deprecated since Ubuntu9.04, i tried it anyways.

Content of the file is


# control-alt-delete - emergency keypress handling
# This task is run whenever the Control-Alt-Delete key combination is
# pressed, and performs a safe reboot of the machine.

description "emergency keypress handling"
author "Scott James Remnant <>"

start on control-alt-delete

exec shutdown -r now "Control-Alt-Delete pressed"


Thanks in advance

Ctrl+Alt+Del may be defined as an application shortcut in Xfce Settings -> Keyboard.

Hi catkin, I've tried that, but it doesnt work.
1. As far as I understand, this setting is for user profile. It will not work when no user is logged in (login screen waiting for login)
2. I've tried setting a keyboard shortcut for <Control><Alt>Delete to '/sbin/reboot', and that doesn't work. Also tried a 'gksudo /sbin/reboot', still doesn't work.
This key should be set in /etc/init/control-alt-delete.config , but somehow XCFE seems overrides it, and it's now specific where the override resides.
3. I've tried to remove the <Control><Alt>Delete from the user's keyboard shortcuts, still reboot does not pick it up from 'etc/init/control-alt-delete.config'.
