Screen sharing

On Wayland, screen sharing is done through PipeWire.

Prerequisites

Make sure you have pipewire, wireplumber and xdg-desktop-portal-hyprland installed, enabled and running.

Ensure that the bitdepth set in your configuration matches that of your physical monitor. See Monitors.

Xwayland

If your screen sharing application is running under Xwayland (like Discord or Skype), it can only see other Xwayland windows and cannot share an entire screen or a Wayland window.

The KDE team has implemented a workaround for this called xwaylandvideobridge. You can use this AUR package on Arch Linux. Note that Hyprland currently doesn’t support the way it tries to hide the main window, so you will have to create some window rules to achieve the same effect. See this issue for more information. For example:

hl.window_rule({
    name = "xwayland-video-bridge-fixes",
    match = {
        class = "xwaylandvideobridge"
    },

    no_initial_focus = true,
    no_focus = true,
    no_anim = true,
    no_blur = true,
    max_size = {1,1},
    opacity = 0.0
})
