libseat - seatd vs logind, systemd, polkit - remote access, no TTY?

[dylanetaft]

My goal is to be able to log into a headless setup with VNC or some moonlight based client.
I have no real access to a normal TTY - however a GPU is in the system. It's installed on an Ampere Altra arm server.
I am on Gentoo, using GIT compiled hyprland sources. I am using the nouveau driver on a 1660 super.

greetd seems to be able to launch hyprland, I don't see a way to get something like wayvnc working there though. Hyprland does start without error though.

I have some hunch that seatd or logind might help - I don't have polkit installed. Is "logind" referenced here referring to systemd's implementation? Or like the standalone elogind? Does hyprland work with systemd's built in logind implementation? That is running.

Am I beating a dead horse here? Not possible to launch hyprland straight from a SSH session, and then VNC into it?

uwsm? Can it launch as a systemd user service in lieu of manual launch on a TTY? The TTY thing is throwing me off.

Weston has a built in RDP and VNC service. They aren't the best but it functions.

I can get DRM + headless easy on sway. It launches from a non TTY no issue.

So far not seeing a way to do this with hyprland
