Ok, I got something like this going with XDMCP.
Step 1: do not read http://tldp.org/HOWTO/XDMCP-HOWTO/procedure.html, I found
it confusing.
Step 2: on DOMU install xdm, and modify
/etc/X11/xdm/xdm-config:
comment out DisplayManager.requestPort: 0
/etc/X11/xdm/Xaccess:
add IP address of server (DOM0)
(I assume this means nobody else will be able to connect but I haven't
tested this)
Step 3: on DOM0 start X:
X :1 -query $IP_address_of_DOMU
or
Xephyr :1 -query $IP_address_of_DOMU
(change or omit :1 as appropriate)
The magic cookie stuff happens automagically (at least for me),
although I can only log in so far in fail safe mode (push F1 instead
of enter to login) because my .xsession file is broken (probably
forgot to install something vital).
It should also be possible to do the same thing with gdm, kdm, etc.
Hmmm... never used Xephyr before... doesn't seem work very well with a
tiled window manager unfortunately :-(. Really needs a free form
window.
