Fwd: Is disabling ctrl-alt-backspace really such a good idea?

[Remco]

Client applications, and even X.org itself, will always have bugs.
They are created by humans, and we are not perfect. In that respect,
it is normal behaviour. So C-A-B will never become obsolete.

Things that can happen:

* Client can grab keys but hang.
* System can become too slow to be usable.
* Xorg/drivers can have a bug that locks the screen.

All of these things will happen in the future, no matter what you do.
C-A-B will fix it in many cases. Hitting C-A-B twice is preferred over
a dialog, because you can't reasonably react to a dialog if the system
is too slow to be usable.
