I have! It was originally even worse than that, I had both servers fighting
over video memory, a few times my system's console froze, etc. That
eventually got fixed about 6-9 months ago. Then I still had the problem
you're having. I eventually got it half way workable by only starting one
server, then starting up the other later. I think I actually started both,
then when I needed to get the second server, switched over to the display
it was on and let it run. It's been a while since I did this, so I don't

That's a bit clumsy. It'd be easier to start one server the usual way,
then for each extra server you want, do "X :n.0 -query localhost". That makes
X connect to the xdm on the localhost, and you don't need to send xdm any
