Hi.

Since NetBSD switched to XF86 4.x I can't use my SGI machines as remote
display for NetBSD X11 clients. The NetBSD machine is a Sun Ultra 10
running a 32 Bit kernel with NetBSD/sparc userland. The SGI is an Octane
with ESSI + ESI dual head GFX running xinerama. I had no problems using
the Octane as remote display with NetBSD when the NetBSD X11 was based
on XF86 3.x.

Symptome:
[jkunz@Zimbo jkunz]$ export DISPLAY=3DMrPomeroy:0.0
[jkunz@Zimbo jkunz]$ xclock
Xlib: Did not parse entire setup message: parsed: 848, message: 1600
Error: Can't open display: MrPomeroy:0.0
[jkunz@Zimbo jkunz]$ uname -a
NetBSD Zimbo 2.0 NetBSD 2.0 (Zimbo) #0: Thu Dec  9 15:43:28 CET 2004
jkunz@Zimbo:/usr/src/build/Zimbo sparc64

I traced the connection with ethereal. After the TCP connection is
established the client sends a 12 byte long X11 request to the server
and the server responds with a 1608 byte long X11 event. Upon reception
of this X11 event the client closes the TCP connection immediately.

Unfortunately I don't have any other machines with working X11 server
instalation beside various SGIs. If it helps debugging I can set up a
SBus SPARC with CGSIX and NetBSD 2.0 to use as test X11 server.

Some info about the Xserver machine:
