# cua-compositor: a minimal headless wlroots compositor that cua-driver spawns
|
|
# as its nested session (CUA_WAYLAND_NEST_COMPOSITOR=cua-compositor) to perform
|
|
# focus-free keyboard injection and multi-cursor pointer injection via a unix
|
|
# control socket. Built from wlroots' own upstream tinywl example (pinned to the
|
|
# same wlroots_0_19 the patch targets) transformed by cua_compositor_patch.py —
|
|
# so it tracks the exact wlroots API in nixpkgs and needs no vendored C.
