In Ubuntu you can disable it in the shortcut menu http://ubuntuhandbook.org/index.php/2013/07/use-ctrl-alt-del-task-manager-ubuntu/ I have already tried editing the file located at
and commenting it all out (it does absolutely nothing).
how can I stop it doing something when I press control alt delete.
i am using Freya 32 bit
and the output of
systemctl mask ctrl-alt-del.target is command not found
