While this function is still enabled by default in new releases, the keymap data usually used with Xorg, from the xkeyboard-config project, has been modified to not map that sequence by default, in order to reduce the chance that inexperienced users will accidentally destroy their work. Users who wish to have this functionality available by default may enable it via the XKB configuration option “terminate:ctrl_alt_bksp”. For instance, the setxkbmap command can be used to enable this by running: setxkbmap -option "terminate:ctrl_alt_bksp" Many desktop environments include XKB configuration options in their preferences to enable this as well. ===Simple Stupid dontzap Tool===Someone made this to make it easy I suppose. sudo apt-get install dontzapOpen Terminal and type to enable sudo dontzap --enableAnd to disable sudo dontzap --disable In current Ubuntu releases, at least since 14.10, the keyboard-configuration package has an option to re-enable Zap: sudo dpkg-reconfigure keyboard-configuration [[Category:Linux]]
