So Wayland won’t be the default display manager in GNOME 3.12. It might not be available either as a tech preview. Can GNOME 3.12 run in Wayland? Yes, and almost every application works as expected. Last time I tried it was ~3 months ago, so I guess things looks much better today.
The most annoying issue is that you can’t set GDM to start a Wayland session, something that might be ready before 3.12 release.
Wayland on bare metal does not work on proprietary drivers yet, but it might be possible to use open drivers on the fly (even if you have NVIDIA installed and enabled), depending on what libGL you link to, and what kernel module is controlling the device.
Notice that Shell even when Wayland port is done, it will be able use both X and Wayland.
Matthias Clasen today gave a short briefing of the current status:
I’ve been dragging my feet on giving an update on the status of porting GNOME to wayland. Always too busy with other things… but today we had a hangout with many of the people that are involved in the porting work and looked discussed where things stand.
GNOME 3.12 / Wayland will still be preview. There are still too many unfinished tasks, and we are only a few short weeks away from hard code freeze. We don’t want to risk destabilizing the X support at this point, so we will defer the merging of the mutter-wayland branch until after 3.12. And we will of course continue working on the TODO list right after 3.12, some of the gaps can probably be fixed in stable updates.
Things that currently work
– basic functionality of gnome-shell as a Wayland and X11 compositor
– display configuration
– color management
– message tray and hot corner
Things that we are still hoping to complete for 3.12:
– launch Wayland sessions from gdm (using logind)
– use libinput for input
– clutter apps
Things that we don’t expect to work in 3.12.0
– input configuration
– wacom tablets
– startup notification
– dnd and clipboard support
– status icons
Big thanks for the things that do work go to Jasper, Giovanni, Rui, Adel, Jonas, Peter and everybody else who worked very hard on the Wayland port, in particular in the last few weeks.
I’ll try Wayland tomorrow or the day after, and give some more info!
