Re: [trinity-users] avoid "Ctrl-Ald-Del" in screen unlock dialog

   That's a
good idea, so I did it. After I sent "Ctrl-Alt-Del" from the
 "F8-menu" of xvnc4viewer (when the screen was *not* locked), TDE opened
 the "End session for 'ilya'" dialog (with a dragon sleeping on the
 moon). And that is not the same dialog as I got by pressing C-A-Del
 physically today. 
 Looks like ctrl+alt+delete of vnc is not ctrl+alt+delete from the keyboard
 :-)

 You can try to figure out what is sent by calling "xev" and analyse the
 output.

TDE monitors the first keyboard it finds for the Ctrl-Alt-Del keypress via
evdev.  The only ways to make this work are:
1.) if vnc registers as a keyboard to evdev somehow (unlikely)
2.) A security hole is opened by monitoring vnc for input
3.) (best) vnc is detected and the ctrl+alt+del input requirement is
deactivated

A TDE bug report on this would be a good idea.
