My wife is sitting at her home desktop,
alpha, which is running a recent version of Ubuntu. I am on a bus, using ConnectBot on my G1 phone, and can SSH into
alpha from wherever I am.
For complicated reasons, I cannot use IM, email, or the telephone in order to contact her. (E.g. I don't want to wake the baby, my IM client is broken, my email server is down.) My only option is to ssh into
alpha remotely and try to somehow make something appear on the screen. She's using KDE; how can I make something pop up to get her attention and let her know I'm trying to communicate with her? I thought it was possible to remotely trigger something (like xmessage) to appear on her screen even though my SSH session doesn't have an X display.
EDIT: To clarify, my phone is not running any flavor of X, so X-over-ssh is not possible. Would the following work?
$ export DISPLAY=:0 $ xmessage "test"
