Change owner(s): Ray Strode <rstrode at redhat.com>
Change the Login screen that GDM uses to run on Wayland instead of X.
== Detailed Description ==
At the moment, a user can choose to log in to a Wayland session from the login
screen, but the login screen itself always runs on top of X. The point of this
change is to change that, and make the login screen always run on a Wayland
session.
== Scope ==
* Proposal owners: The main things that need be accomplished are:
** Change GDM to not start an X server at startup, instead run the login
screen in Wayland mode
** Change X based user sessions to run on their own VT, since they can no
longer piggyback off the login screen VT
** Come up with some answer for proprietary Nvidia driver users, since that
stack doesn't yet support Wayland. One idea is to force the login session to
use software-based mesa if the proprietary Nvidia driver is detected.
* Other developers: We may need to get the mesa maintainer involved as part of
a proprietary Nvidia driver handling, but also might not need to pending
investigation.
* Release engineering: This change doesn't affect release workflow
* Policies and guidelines: This change doesn't affect packaging guidelines
== Contingency Plan ==
* Contingency mechanism: Revert to existing mechanism of login screen on Xorg
* Contingency deadline: Beta Freeze
* Blocks release? No
* Blocks product? No
