Documentation/notes for screensharing

Describe the issue

I had issues sharing my screen, got some help and handholding.

Notes

• must have xdg-desktop-portal-wlr installed
• should have /usr/share/xdg-desktop-portal/wayfire-portals.conf or ~/.config/xdg-desktop-portal/wayfire-portals.conf

[preferred]
default=wlr;*
org.freedesktop.impl.portal.Inhibit=none

May have other content...

• must have env variables:

XDG_CURRENT_DESKTOP=wayfire
XDG_SESSION_TYPE=wayland

• must have ~/.config/xdg-desktop-portal-wlr/config

[screencast]
output_name=DP-3   <- modify as needed, value may not be hugely important(?)
max_fps=30
chooser_cmd=slurp -f ’Monitor: %o’ -or

• May use wlr-randr to figure out output names.

• must have pipewire enabled

systemctl enable --now --user pipewire

• must(?) autostart xdg-desktop-portal-wlr with wayfire:

[autostart]
0_0 = (XDG_SESSION_TYPE=wayland XDG_CURRENT_DESKTOP=wayfire systemctl --user import-environment)
autostart_wf_shell = false
idle = swayidle before-sleep swaylock
notifications = mako
outputs = kanshi
portal = /usr/libexec/xdg-desktop-portal-wlr

Review the listed xdg-desktop-portal-wlr configuration paths, environment variables, PipeWire command, and Wayfire autostart block. Turn these notes into project documentation with clear prerequisites and setup steps, preserving the configurable output name and chooser command details.
