Where is my "Ctrl + Alt + Backspace" ?

After installing ubuntu 10.04, I quickly realized that CRTL-ALT-F1 (for opening a terminal) and CRTL-ALT-BACKSPACE (for killing X-server) are gone. Luckily, here is the solution I found:

Enabling Ctrl-Alt-Backspace for Ubuntu 10.04

1. Select “System”->”Preferences”->”Keyboard”
2. Select the “Layouts” tab and click on the “Layout Options” button.
3. Select “Key sequence to kill the X server” and enable “Control + Alt + Backspace”

Enjoy your hot keys :)
