Bug#405639: xserver-xorg: installs arbitrary -input and -v..

Package: xserver-xorg
Version: 7.1.0-9
Severity: grave
Justification: renders package unusable

when installing xserver-xorg (by way of xorg) in a newly built LTSP
chroot environment, it seems to select an arbitrary -video and -input
package. i ended up with the following video/input and nothing else:

xserver-xorg-video-apm
xserver-xorg-input-acecad

i suspect this is because of the recent changes to the dependencies to
try and fix #403818:

Depends: xserver-xorg-core (>= 2:1.1.1-11), xserver-xorg-video-1.0,
xserver-xorg-input, debconf (>= 0.5) | debconf-2.0, xkb-data |
xkb-data-legacy, xbase-clients
Recommends: xserver-xorg-video-all | xserver-xorg-video-vesa,
xserver-xorg-input-all | xserver-xorg-input-mouse, xserver-xorg-inpu
t-all | xserver-xorg-input-kbd, laptop-detect, xresprobe, mdetect,
discover1 | discover

this allows any package providing xserver-xorg-video-1.0 to satisfy the
dependency. same for xserver-xorg-input. if using apt-get, it will not
typically consider the recommends, and apt appears to arbitrarily select
whichever package it comes across first that satisfies the dependency.

i suspect the following would be better:

Depends: ... xserver-xorg-video-all | xserver-xorg-video-vesa | xserver-xorg-video-1.0, xserver-xorg-input-all | xserver-xorg-input-mouse | xserver-xorg-input, xserver-xorg-input-all | xserver-xorg-input-kbd | xserver-xorg-input ...

this will default to using -video-all, fall back to -video-vesa, and
allow anything providing -video-1.0 to satisfy the dependency.

similar with -input, though the above still could leave you with only
one of -mouse or -kbd. i have no idea how to get that perfectly while
still allowing for unusual -input configurations.

thanks!

i suspect this will also happen if a user selects the Desktop task from
debian-installer, as tasksel uses "aptitude --without-recommends". and
that's probaly not the only package burned by this bug (i think ltsp and
live-package are suffer).

is there some other way the upgrading issues could be addressed?
