would this works, say in .zlogin, to say that X is up:

exit 1;

or is there something more clever?

I'm not sure if it's any cleverer, but I would probably make a call to
pgrep(1) instead of relying on the existence of a file that might exist,
even if X isn't running (unusual, but it does happen now and then, here at
least) - something like

if (pgrep "Xorg")
then
echo "X is up."
exit 0
else
echo "No X yet..."
exit 1
fi

... should do the trick.

And bear in mind that ~/.zlogin is run *after* ~/.zshrc, whereas ~/.zprofile
is run *before* it. It might matter, depending on what you are trying to do.
