Subject: /etc/X11/default-display-manager needs to be set so gdm does not complain every boot

Date: Fri, 21 Jul 2006 19:50:28 -0400

Package: gdm
Version: 2.14.5-1
Severity: minor

i'm not sure which package should be in charge of this (maybe xorg), but
/etc/X11/default-display-manager should be defined.  the consequence is
that during every boot, gdm complains that the /etc/X11/default-display-manager has not been set.

even though the severity of this bug is minor, it should certainly be
cleaned up before the release of etch.

thanks for the hard work.

Subject: issue with noninteractive selects and debconf passhrough

Date: Sun, 29 Oct 2006 23:56:12 -0500

[Message part 1 (text/plain, inline)]

#379198 turns out to be due to a bug in the passthrough frontend, when
used with debconf-apt-progress to install gdm. This happens:

debconf (developer): <-- METAGET shared/default-x-display-manager owners
debconf (developer): --> 0 gdm
debconf (developer): <-- METAGET shared/default-x-display-manager choices
debconf (developer): --> 0 
debconf (developer): <-- SUBST shared/default-x-display-manager choices gdm
debconf (developer): --> 0
debconf (developer): <-- FSET shared/default-x-display-manager seen false
debconf (developer): --> 0 false
debconf (developer): <-- INPUT high shared/default-x-display-manager
debconf (developer): Not displaying select list shared/default-x-display-manager with 1 choice
debconf (developer): --> 30 question skipped
debconf (developer): <-- GO
debconf (developer): --> 0 ok
debconf (developer): <-- GET shared/default-x-display-manager
debconf (developer): --> 0

The noninteractive select list handling should make the value be the
first item on the list, "gdm", but this doesn't happen. So this bug
could affect more than gdm; the reported but never really tracked down
issues with wordlist selection questions could also be caused by this.

I came up with the attached patch, which I've tested to work, and which
seems to make perfect sense to me..

Except that it seems possible that Colin might have rejected doing it
this way for some sensible reason that I'm not seeing. Colin, I hope you
can review this..

Looks entirely correct to me, and I'm glad you spotted that. Not sure
why I did it this way to begin with; it's possible I simply hadn't quite
got the hang of debconf's object model yet.

This could also explain #393427, although I think the workaround (adding
a Default) was correct anyway.

Cheers,
