Thanks. Hmm, I suspect that the lines that I described were actually
ones that I added in an earlier attempt to make this work - sorry.
Anyway, when I investigated this at the start of December I did
understand it all and got it working correctly, and I'd like to
encourage you use the Xstartup file below which files the following problems:
1. A "no home directory" message is displayed (this bug).
2. /etc/nologin works with the /etc/nologin message being displayed,
rather than simply displaying "login incorrect" as currently happens.
(bug #118677). For this to work you also need to prevent PAM from
doing the nologin test itself; see my comment in bug #118677 where I
point out which line to remove.
Xstartup file follows.
