The stream rendered but ignored keyboard and mouse. Sunshine injects input
through uinput exclusively — it has no support for the Wayland virtual
keyboard/pointer protocols — so the compositor has to have a libinput
backend to see those devices. WLR_BACKENDS=headless creates only the
headless backend, so sway had zero input devices against the kernel's 24.
libinput needs a seat, and a systemd --user service belongs to no logind
session, so libseat needs seatd. seatd is now enabled on this host.
Its socket defaults to group `seat`, which does not help here: the user
manager's group list is fixed when it starts, Linger=yes means that is at
boot, and so adding connor to `seat` would not take effect until a reboot —
re-logging in changes nothing. The drop-in points seatd at `video`, a group
connor already holds for GPU access, which makes this deterministic instead
of dependent on group-propagation timing.
sway now reports 7 input devices including libvirtualhid Mouse and
Keyboard, which are Sunshine's.
hosts/mainframe/etc/ is a new tree for system-level config; install flags
it the same way it flags sbin.
