I personally use screen a lot, this email was typed in a screen session, 
for example but the others that are using this will want to keep other X 
apps running, like emacs and various test interfaces. (I know you can 
run emacs from the console as well).

It turns out Cam was right. The -query option is not necessary.

In fact -query tries to get the greeter to pop up. That's why XDM was 
interfering. It should have been using the gdm greeter but hey-ho. As 
these sessions belong to the user who started them, we don't need a 
greeter at all.

I've not found any documentation about this but other servers where the 
greeter is configured correctly (a solaris CDE), with the -query option, 
gives you a greeter and without launches you straight to the windowmanager.

Thanks guys.
