Again, changes to the kernel and DM along with three system libraries were
made to support the new server.  SR10.3 + pskq2_91 is needed (or SR10.3 +
psk8 + psk8x_040).

Any chance you could update a single node of your's and check things out ?
We actually found SR10.3 to be far more solid than SR10.2.

The performance should be improved, and the borrow mode mechanism is enhanced.
With the MIT version, the server must be killed before the DM returns.   With
the new server, you can toggle between X and the DM without blocking/killing
either.

Both sides remain active.   Example: when you have the DM active, the X side
just acts like the screen saver was kicked on (ie, a fake black window is
mapped over the entire screen and all X clients just think they're obscured).
A few other things happen, but suffice it to say nothing is blocked and 
everything works fine (both ways).

I saw your previous question, but didn't know how to respond.   I believe
not.   If you understand X's cut buffers (old method ?) and selections (new
method ? ICCCM ?), it might be possible to write a client that could feed
X buffers into the DM.

For X, see the file /sys/node_data/etc/X0pointerkeys, the bottom section.

For the DM, see section 1.1.2.1 of the pskq2_91 release notes.

Depends.  If xdm is started from bootup, no DM exists.

If xdm is fired up from outside a DM session (rlogin, cron, whatever), yes,
you have to log in twice :-(    All I can say about this: a feature is born
every minute.

Actually, if you log into the DM and fire up xdm, you'll have to log into
xdm once again.

Its a fully loaded X11R4 server.  It includes:
     o Shape Extension
     o Input Extension
     o Input Synthesis Extension
     o Multibuffer Extension
     o MIT Misc Extension(s)

It also includes scalable font technology.

/etc/Xdomain is the new server.  /etc/Xapollo remains as the share mode server.
