A seat manager mediates access to input and output devices such as keyboards and monitors. Wayland requires a seat manager. Alpine Linux provides two different seat managers:

  • seatd: a minimal seat management daemon.
  • elogind: login manager extracted from systemd.

Input and video groups

Some instructions mention the need for the input and video groups. This is in most cases incorrect and insecure! The seat manager already provides the necessary permissions. Due to issue #15409 there is currently 1 exception: If you aren't using elogind and need PipeWire to access a webcam you need the video group.
