Sorry for the large to/cc list but I want to tell you of something I
did which may be considered a no-no. I changed configuration of
auditorium and now has X properly working.
The problem was that the wrong X server was trying to be used.
The following changes were required:
a) I installed Xtx in /etc. (I extracted it by
cd /mit/mips_subsets/4.2A
cat UDWXTXSER425 | zcat | (cd /tmp; tar xvf -)
cp /tmp/usr/bin/Xtx /etc
b) Changed /etc/athena/login/config to point at new X server and at
100dpi.

c) Created
/etc/athena/xserver.conf:
auditorium# cat > /etc/athena/xserver.conf
100DPI
This will ensure that future updates will know that this
machine is 100dpi.
What should be done:
a) determine if the default kernel options will work on this machine.
(I suspect yes).
b) If this machine configuration will be supported, fix do_update and
phase2.sh and the system packs to include this X server (in the next
release). (Oops - don't forget to include the X server as an exception
in the track rules as well)
c) Get another monitor next to the machine. Boot using
3/rz2/vmunix -a -mg
and see if proper two headed support actually works....
That is all....
