Title: Plasma Profile to switch on PipeWire, Wayland support Author: Andreas Sturmlechner <ast...@gentoo.org> Posted: 2023-05-20 Revision: 1 News-Item-Format: 2.0 Display-If-Profile: default/linux/amd64/17.1/desktop/plasma Display-If-Profile: default/linux/amd64/17.1/desktop/plasma/systemd Display-If-Profile: default/linux/amd64/17.1/desktop/plasma/systemd/merged-usr Display-If-Profile: default/linux/amd64/23.0/desktop/plasma Display-If-Profile: default/linux/amd64/23.0/desktop/plasma/systemd
1. PipeWire Gentoo's Plasma profile has not had any sound server enabled since the days of KDE's own aRts. As the way we output sound has changed dramatically in the years since - using wireless or often several devices, dynamically connected and shared between multiple systems, a modern desktop environment is expected to handle this effortlessly by default. This means the profile will enable both USE="pipewire,pulseaudio" globally, and enable media-video/pipewire[sound-server] to make it act as our PulseAudio server. User action required: - Check out what, if anything, you should configure to make PipeWire work for your purpose [1]. - For kde-apps/kmix users, a second sound mixer will appear in system tray: kde-plasma/plasma-pa as pulled in by kde-plasma/plasma-meta. Quit KMix and it will not re-appear on next startup. - If you want to keep your PipeWire or ALSA-only setup, invert above USE flag settings globally, as needed. 2. Wayland Plasma Wayland support has come a long way and we consider it stable enough for daily use with a lot - if not all - systems, even if some known papercuts remain [2]. For those willing to switch it makes sense for Plasma profile to already provide sane settings. For everyone else it means only negligible impact in dependencies, as most of it was already inevitable with kde-plasma/plasma-desktop and its dependencies. Plasma profile will enable both USE="wayland,screencast" globally. The latter flag is tied to the video functionality of PipeWire, and e.g. used to 'cast' window content onto task managers' window previews. This is why PipeWire and Wayland enablement are happening at the same time. User action required: - If you want to keep your PipeWire or ALSA-only setup with Wayland, note that media-video/pipewire installation can not be avoided, but configuration not to act as a sound server is possible [1]. - None. No one will lose their X session, but will have the option to easily log into a working Wayland session instead.
