[ale] frontend: Dialog ?

[Jeff Lightner]

If you had an X tunnel working for X windows on the user you initially
logged in as via ssh you can make this available to the root user after
you su  or sudo su:

export XAUTHORITY=~<originaluser>/.Xauthority

That lets it use the tunnel you'd already established for the original
user.

Or, `xhost +root` as the user running X. Then it won't matter how you
assume root.

But that, in my opinion, is overkill for this problem. I think it
would be much better to reconfigure dpkg to use terminal based prompts
(ncurses or otherwise) instead of the X prompt.
