Public bug reported: On the Wayland session using an Nvidia GPU, enabling the Night Light setting in the Settings app doesn't change the screen colour temperature to a warmer hue regardless of "Sunset to Sunrise" or "Manual Schedule" being selected. Switching to the X11 session results in Night Light working as expecting.
I'm currently using the Nvidia 510.60.02 driver (RTX 2080Ti). $ lsb_release -rd Description: Ubuntu 22.04 LTS Release: 22.04 $ apt-cache policy gnome-shell gnome-shell: Installed: 42.0-2ubuntu1 Candidate: 42.0-2ubuntu1 Version table: *** 42.0-2ubuntu1 500 500 http://gb.archive.ubuntu.com/ubuntu jammy/main amd64 Packages 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu 22.04 Package: gnome-shell 42.0-2ubuntu1 ProcVersionSignature: Ubuntu 5.15.0-27.28-generic 5.15.30 Uname: Linux 5.15.0-27-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.20.11-0ubuntu82 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME Date: Mon May 9 22:01:57 2022 DisplayManager: gdm3 InstallationDate: Installed on 2022-04-29 (10 days ago) InstallationMedia: Ubuntu 22.04 LTS "Jammy Jellyfish" - Release amd64 (20220419) RelatedPackageVersions: mutter-common 42.0-3ubuntu2 SourcePackage: gnome-shell UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: gnome-shell (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug jammy wayland-session -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1972728 Title: Night light not working on Nvidia Wayland Status in gnome-shell package in Ubuntu: New Bug description: On the Wayland session using an Nvidia GPU, enabling the Night Light setting in the Settings app doesn't change the screen colour temperature to a warmer hue regardless of "Sunset to Sunrise" or "Manual Schedule" being selected.
