Wayland Desktop features progress
This purpose of this page is to list the current missing or incomplete features in GNOME on Wayland to achieve a user experience on par with what is found on X11.
This page is not meant to lists known bugs or issues with existing features, nor how to debug Wayland issue, see How to debug Wayland problems for this.
It focuses primarily on GNOME because GNOME is the default desktop on Fedora Workstation, but features may need to be implemented at different levels not necessarily part of GNOME:
* kernel: drm, evdev, etc. * libraries: underlying libraries, e.g. libinput, libwayland, etc. * protocol: requires a new Wayland protocol or amending an existing protocol * Xwayland: X11 compatibility * mutter: Wayland compositor * gtk+: toolkit, handles client side decorations in Wayland * apps: requires new applications
Remote display

Screencast

on-screen keyboard
protocol, mutter
Not sure if we'd need a new app for that.

protocol, libraries

hi-dpi support
protocol, gtk+, mutter
Not sure what is meant by that, Wayland supports scaling of surfaces and mutter uses that afaik.
attached modal dialogs
gtk+, mutter
This should use the existing "set_parent" request in xdg-shell protocol.
tablet support
protocol, libraries, gtk+
startup notification
protocol, libraries, gtk+, mutter
clipboard proxy for xwayland
Xwayland
Not sure what is meant by that, copy/paste already works between Wayland native and Xwayland apps.
touch proxy for xwayland
protocol, gtk+, mutter, Xwayland
Not sure what is meant by that, touch was added in Wayland and Xwayland by Carlos.
accessibility features
protocol, gtk+, mutter
output rotation
mutter, apps
Wayland protocol already supports output transformation, supported by Xwayland and weston can use it.
XRandR control of Wayland outputs
protocol, Xwayland
There is a "read-only" XRandR support in Xwayland, but it cannot send request back to the Wayland compoisitor so X11 applications have no control over the output configurations.
Screensaver control
protocol, mutter, Xwayland, apps

Xfree86-VidModeExtension in Xwayland
protocol, Xwayland
Some games check for this extension and would refuse to start without. There are patches contributed but these are incomplete and not satisfactory.
Beside, this is the same a current XRandR support, i.e. read-only, Xwayland apps cannot control the output configuration.
