- render Niri on the Intel iGPU while retaining NVIDIA-connected physical outputs - encode Sunshine streams with Intel VAAPI and wait for a Niri output before startup - load VKMS persistently for headless sessions and configure `Virtual-1` at 2560x1600@60 - let Moonlight request the stream bitrate instead of enforcing a 20 Mbps host cap - remove unsupported Dynamic Boost and global NVIDIA session overrides - grant Sunshine access to virtual input devices - add a Nushell recovery helper that starts a temporary greetd/Niri session from SSH - identify and safely replace normal, standalone, or previous transient Niri sessions - launch the transient service in the background and verify greetd, Niri, and Sunshine before returning - ignore local `.worktrees` directories and keep eval regression coverage focused on structural behavior

# Temporary remote session recovery
|
|
|
|
When a remote-only machine is stuck at the `greetd` TUI, run the Nushell helper from an
|
|
SSH session to start one complete PAM/logind Wayland session without changing
|
|
the persistent NixOS configuration:
|
|
|
|
```bash
|
|
sudo nu ./remote-session.nu
|
|
```
|
|
|
|
The helper validates its dependencies before changing the current session. It
|
|
then stops the normal `greetd` service, starts a transient systemd-managed
|
|
`greetd` configuration on `/dev/tty1`, and runs Niri directly. It returns after
|
|
greetd, Niri, and Sunshine are ready. Tailscale is not affected.
|
|
|
|
The `Virtual-1` output is created persistently by the `vkms` configuration in
|
|
`hosts/idols-ai/hardware-intel.nix` and configured by
|
|
`hosts/idols-ai/niri-hardware.kdl`. It gives Niri and Sunshine a capture target
|
|
when both physical monitors attached to the NVIDIA GPU are off. The output also
|
|
exists during normal physical sessions; keeping an idle virtual framebuffer has
|
|
minor GPU and memory overhead.
|
|
|
|
Options:
|
|
|
|
```text
|
|
-u USER session user (defaults to SUDO_USER)
|
|
-t TTY tty device, for example /dev/tty2
|
|
-c COMMAND Wayland session command (defaults to niri --session)
|
|
-f, --force replace an existing Niri session without confirmation
|
|
--check validate prerequisites without changing service state
|
|
```
|
|
|
|
A reboot or a manual restart of `greetd.service` restores the normal TUI
|
|
configuration.
