# ScreenCast portal (xdg-desktop-portal-wlr) and the lumen host share one bus. After this

# vendor JSON; without it wlroots can't init EGL on the GPU and falls back to pixman,
|
|
# which the ScreenCast portal cannot capture.
|

# - membership in the `render` + `video` groups (re-login after `usermod -aG`).
