Bug Description

Ctrl+Alt+Backspace (i.e. the shortcut which was used to restart the X server) has to be enabled in a different way with respect to previous releases of Ubuntu. This is due to the fact that "DontZap" is no longer an option in the X server and has become an option in XKB instead.

The attachment contains a draft of the instructions for GNOME, KDE and a link to the wiki to be added to the release notes.

Added at <https://wiki.ubuntu.com/KarmicKoala/ReleaseNotes#Ctrl-Alt-Backspace%20disabled%20by%20default%20in%20Xorg,%20configured%20via%20XKB> with a few changes, thanks!

Since Ubuntu 9.04, the Ctrl-Alt-Backspace key combination to force a restart of X is now disabled by default, to eliminate the problem of accidentally triggering the key combination. In addition, the Ctrl-Alt-Backspace option is now configured as an X keymap (XKB) option, replacing the X server "DontZap" option and allowing per-user configuration of this setting.

As a result, enabling or disabling the Ctrl+Alt+Backspace shortcut can now be done easily from the desktop.

Enabling Ctrl-Alt-Backspace for Ubuntu

    * Select "System"->"Preferences"->"Keyboard"
    * Select the "Layouts" tab and click on the "Layout Options" button.
    * Select "Key sequence to kill the X server" and enable "Control + Alt + Backspace".

Enabling Ctrl-Alt-Backspace for Kubuntu

    * Click on the Application launcher and select "System Settings"
    * Click on "Regional & Language".
    * Select "Keyboard Layout".
    * Click on "Enable keyboard layouts" (in the Layout tab).
    * Select the "Advanced" tab. Then select "Key sequence to kill the X server" and enable "Control + Alt + Backspace".
