Reasons
|
||
|
=======
|
||
|
|
||
|
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.
|
||
|
|
||
|
In Wayland sessions, the video functionality of PipeWire is not only used for
|
||
|
screensharing but also to take screenshots and -recordings or simply to cast
|
||
|
window content onto task managers' window previews. This is why PipeWire and
|
||
|
Wayland enablement are happening at the same time.
|
||
|
|
||
|
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 [1]. Therefore it makes sense for Plasma profile to provide sane default
|
||
|
settings.
|
||
|
|
||
|
|
||
|
Changes
|
||
|
=======
|
||
|
|
||
|
New global USE flags enabled: pipewire, pulseaudio, screencast, wayland
|
||
|
New package.use default: media-video/pipewire[sound-server]
|
||
|
|
||
|
We want broad sound server support in packages, and these settings will make
|
||
|
PipeWire act as our PulseAudio server where there is no native PipeWire support.
|
||
|
|
||
|
|
||
|
Impact On Happy X Users
|
||
|
=======================
|
||
|
|
||
|
Minor. Most dependencies were already required with kde-plasma/plasma-desktop
|
||
|
and its dependencies. Upcoming stable versions of kde-apps/spectacle and
|
||
|
kde-apps/krfb will depend on (K)PipeWire unconditionally.
|
||
|
|
||
|
No one will lose their X session, but will have the option to easily log in to
|
||
|
a working Wayland session at any time.
|
||
|
|
||
|
It is possible to set USE="-wayland" against these changes, but it will amount
|
||
|
to no dependency savings, just micro-optimisation in affected packages.
|
||
|
|
||
|
|
||
|
User Action Required
|
||
|
====================
|
||
|
|
||
|
In order to enact all changes:
|
||
|
|
||
|
emerge -1avUD @world
|
||
|
Check out how to configure PipeWire for your purpose [2][3]
|
||
|
|
||
|
In order to keep a PulseAudio or ALSA-only setup:
|
||
|
|
||
|
Invert above new USE flag settings as needed, see also [2].
|
||
|
|
||
|
In order to avoid media-video/pipewire completely:
|
||
|
|
||
|
This can only be achieved by losing basic task manager, screenshot/screen
|
||
|
recording/sharing functions as provided by Plasma and KDE applications.
