Remote access on lea (kwin-noctalia default; niri sandbox in greeter) and vanessa (Plasma).

Punktfunk (gaming / low latency)

• Server: Punktfunk via nixos.punktfunk (unom flake)
• Unit: punktfunk-host (and punktfunk-web) — see modules/nixos/punktfunk.nix
• Protocol: native punktfunk/1 (Moonlight/GameStream is off)
• Clients: Punktfunk client; KDE/gamescope session notes at KDE / gamescope
• Hosts: lea (kwin-noctalia, RTX 4090) and vanessa (Plasma, RTX 2070). Both pin renderD128 as the NVIDIA node.

Polaris/Moonlight is not packaged. KRDP (krdpserver) is not shipped.

Quick start

1. A graphical session must be active (lea: kwin-noctalia autologin; vanessa: Plasma autologin) and systemctl --user status punktfunk-host running.
2. Connect with a Punktfunk client on the LAN.

Security

• Stream ports are opened on the LAN firewall as declared in punktfunk.nix (openFirewall).
• Prefer LAN or VPN; do not expose the stream host to the public internet without a tunnel.
