Errr, surely not :)

What Anton wants is to know whether X is currently at the front or not.
And you can't rely on DISPLAY being set (since you could be from sudo su
-), and you can't rely on stdin being the VT (since you could be from
screen). At best you could test whether the console is in text or
graphical mode.
