Phoronix: How To Make Use Of Wayland Screen Sharing With PipeWire & XDG Desktop Portal

A few days back we reported on the Red hat progress with supporting WebRTC-based screen-casting under Wayland that's working both for KDE Plasma and GNOME Shell. Given all the concerns over the years in supporting screen sharing / remote desktop under Wayland and the bits only coming together recently, Red Hat's Jan Grulich has offered up a guide...

Is this supported in weston? I'm curious if there is an example of a "simple" implementation to show other desktop environments how it works.

pipewire is such a big regression in functionality when comparing to X11 sharing. For instance it does not even support DPI while X11 programs (yes, even GTK3 and Qt5) honour your Xft.dpi settings when doing remote X11.

Why would this be relevant? Isn't this just focusing on sharing the entire screen, not individual applications?

Also the 80s called, they want their software architecture back.

Pipewire is an interesting project. Is it aiming to replace PulseAudio as well?

from the Pipewire website;

''PipeWire is a project that aims to greatly improve handling of audio and video under Linux. It aims to support the usecases currently handled by both PulseAudio and Jack and at the same time provide same level of powerful handling of Video input and output. It also introduces a security model that makes interacting with audio and video devices from containerized applications easy, with supporting Flatpak applications being the primary goal. Alongside Wayland and Flatpak we expect PipeWire to provide a core building block for the future of Linux application development.''

X11 sharing? There's no such thing. There's VNC, but that's not X11. DPI? WTF? This is about those meetings where everyone sits around a big screen / TV, and the remote team dial in and can see your desktop. Not a lot of other applications, and certainly none where DPI is a concern.

He's most likely talking about xdmcp. I e not screen sharing but actually remote access.

Set Xft.dpi in your local .xresources and then launch a remote X program - for instance

local:~/ $ ssh -X myhost
myhost:~/ $ firefox

The remote firefox will respect your local DPI which is extremely useful if you have for instance a retina machine and you connect to a non-retina host, or conversely. This is not possible with pipewire.

Nice question
