Thanks!

I got a litlle further with your help, but not quite there yet :)
startx /usr/X11R6/bin/twm -- -layout tv-out vt8 :1
starts the X server but apparently twm still tries to connect to the
first server since I get these error messages:
/usr/X11R6/bin/twm:  another window manager is already running on screen 0?
/usr/X11R6/bin/twm:  unable to find any unmanaged screens
 
Passing the -display :1 option to twm I run into this:
AUDIT: Mon Aug  2 09:30:11 2004: 19479 X: client 1 rejected from local host
Xlib: connection to ":1.0" refused by server
Xlib: No protocol specified

I think this is because my magic cookies aren't set up right for the
second X server, but I don't know how to fix this. Is there some xrdb
voodoo involved? I cant use xhost to allow access because xhost can't
connect to the second X server either.
