I don't know yet what's going on. I want to record some thoughts here
though.

There's a short list of kinds of bugs that I won't be surprised if
testing reveals in XCB. That list contains both endianness and alignment
bugs. It doesn't look like you're having either of those problems:
both client and server are on x86 architecture which is, of course, what
XCB has received the most testing on; and the fact that you get a very
sensible-looking stream of errors suggests the protocol stream is in
sync and not misaligned somewhere.

Having an unset DISPLAY variable can certainly cause problems. :-) I do
wonder whether that was a sign of something else being wrong. You did
have other X apps running fine, right?

This is consistent with my guess about the root window ID being wacky.

When you have a chance, could you grab the xcb-demo updates I've just
committed and re-test? (The behavior shouldn't change for you, but I've
fixed the BadMatch error that I was seeing, so who knows...) Please try
hypnomoire too; I've added code to it that does a GetGeometry request on
whatever it believes to be the root window and displays part of the
results.

Could you send me (privately, perhaps) the complete build output? I can
probably clear up your build issues. Maybe it'll even make a difference,
though I'm skeptical.

I'd probably accept patches to make XCB build with older versions of
autoconf and automake, too.

Thanks for playing. :-)
