Re: Disable Ctrl-Alt-Del in Jessie [Solved]

Thanks, Martin. With that info, I was able to confirm that the link 'control-alt-del.target -> /dev/null' does disable C-A-D from a tty.  And it took a bit to find it, but the behavior in KDE can be managed in:

System Settings --> Shortcuts and Gestures --> Global Keyboard Shortcuts --> The KDE Session Manager (from the pull down menu)

There are 3 items there which can be configured independently: Log Out, Log Out without Confirmation, and Reboot without Confirmation.  Each can have its own keystroke sequence, or be set to None.

Yeah!  No more erroneous reboots due to Windows screen lock attempts on Jessie! :-)

That logout/reboot/shutdown prompt is a feature of your GUI environment,
which should have a mechanism for configuring it to do something *else*
(or, hopefully, nothing at all) in response to C-A-D.

For example, my XFCE4 environment is configured to lock the console when
I make the three-finger salute.
