The Settings -> Displays panel displays the error: "Night light unavailable this could be the result of the graphics driver being used, or the desktop being used remotely." System details: OS: Ubuntu 24.04 LTS Session Type: Wayland (XDG_SESSION_TYPE=wayland) GPU: NVIDIA GeForce GTX 1660 SUPER (using proprietary nvidia driver) Displays: 3 monitors connected NVIDIA DRM Modeset: Active (/sys/module/nvidia_drm/parameters/modeset returns Y) Steps to reproduce: Boot into Ubuntu using kernel 6.8.0-117-generic with three active monitors on an NVIDIA GPU under a Wayland session. Open Settings -> Displays -> Night Light. Expected result: Night Light toggle should be interactive and apply color temperature adjustments across all active monitors. Actual result: Night Light is completely greyed out with a generic driver/remote desktop warning banner.
