[Bug 29389] Re: fails to install -- possibly due to implicit dependency on default-display-manager?

[Ralph Corderoy]

gdm's postinst has code like

    DEFAULT_DISPLAY_MANAGER_FILE=/etc/X11/default-display-manager
    case "$1" in
    configure)
        if grep "/usr/bin/gdm" $DEFAULT_DISPLAY_MANAGER_FILE; then
            echo "/usr/sbin/gdm" > $DEFAULT_DISPLAY_MANAGER_FILE
        fi
        ;;
    esac

which doesn't check /etc/X11/default-display-manager exists before
grepping it.

Elsewhere, debian/* files do check /etc/X11/default-display-manager
exists before reading it.  debian/changelog says

gdm (2.8.0.0-0ubuntu1) breezy; urgency=low
  * debian/postinst:
    - update the gdm value for default-display-manager.
