Re: Missing X binary

[David Brownlee <abs%absd.org@localhost>]

OK, after a selection of minor issues - gxemul now runs X11 from a
current NetBSD/pmax build

https://twitter.com/abs0/status/1466899301427257347 (as I can't
usefully send a screenshot to the list :)

So issues:
- Working out the seemingly random set of files to tweak to get pmax
to build xf86-video-wsfb
- Finding out that Xorg 1.20 won't build, so switching pmax to using
1.10 (similar to vax)
- X failing to start due to missing WSDISPLAYIO_GET_FBINFO support in
the cfb driver (now added)
- Xorg 1.10 is missing the uxterm binary used by the default ctwmrc
(which is _really_ annoying, if trivial to workaround)
- Thinking the keyboard mapping is all to hell, until I realised that
the key marked <X] sends The Correct Sequence To Delete A Character,
not ^H

Anyway, I'm going to run up a full release build with ISO, and then
upload it with some brief notes in case anyone else wants to have a
play (which will be tomorrow now as I'm currently enjoying a power cut
with a less than full laptop battery), then look to get it in-tree for
the next NetBSD version.
