Comment 34 for bug 1669374

@Jeremy,

if gnome's dev seems blaming 'gdm', that point out an other unexpected mess : when lightdm is reconfigured to use 'lightdm' and/or lightdm is purged then reinstalled, why and how 'gdm' can disturb the X start ?

Seems to me that X/wayland/mir/... relationship is messy: if the user choose to login with lightdm, then none of the other DE should disturb the process.
