This is because the NVidia driver doesn't support setting gamma ramps. In order for night color to work either NVidia has to implement it or we have to implement a (less efficient) shader based fallback Worked on Xorg. Still broken in 5.26.2 and NVidia driver 520.56 with Wayland Has a bug or feature request been submitted to Nvidia? Bug confirmed on my machine. Works on x11 but not wayland. Operating System: Fedora Linux 36 KDE Plasma Version: 5.25.4 KDE Frameworks Version: 5.97.0 Qt Version: 5.15.5 Kernel Version: 5.18.18-200.fc36.x86_64 (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i7-4720HQ CPU @ 2.60GHz Memory: 15.6 GiB of RAM Graphics Processor: NVIDIA GeForce GTX 980M/PCIe/SSE2 Manufacturer: ASUSTeK COMPUTER INC. Product Name: G751JY System Version: 1.0 Relevent packages: Name : akmod-nvidia Version : 515.65.01 & Name : akmods Version : 0.5.7 The specific message logged: kwin_wayland[1069]: kwin_wayland_drm: Failed to create gamma blob! Invalid argument From: https://forums.developer.nvidia.com/t/wayland-information-for-r515-beta-release/214275 The nvidia-drm module does not support the GAMMA_LUT, DEGAMMA_LUT, CTM, COLOR_ENCODING, or COLOR_RANGE connector properties, which may impact some compositor features related to color correction. I want to add that with the Night Color feature enabled, each time the "kwin_wayland_drm: Failed to create gamma blob! Invalid argument" message shows on the logs, the screen freezes (one of them, the other two won't), and it can completely freeze the kwin session. 3 monitors: One Display Port, one HDMI and one DVI. Operating System: Arch Linux KDE Plasma Version: 5.27.4 KDE Frameworks Version: 5.105.0 Qt Version: 5.15.9 Kernel Version: 6.2.12-zen1-1-zen (64-bit) Graphics Platform: Wayland Processors: 12 × Intel® Core™ i7-8700K CPU @ 3.70GHz Memory: 15.6 GiB of RAM Graphics Processor: NVIDIA GeForce GTX 1070/PCIe/SSE2 Nvidia Drivers: 530.41.03-1 Workaround has been to disable this feature completely. Please create a separate bug report for the freeze (In reply to Zamundaaa from comment #6) > Please create a separate bug report for the freeze Done, https://bugs.kde.org/show_bug.cgi?id=468895 Thank you, Git commit cdafbbbd6f80d6ca0639660ed4ec121754553f54 by Xaver Hugl. Committed on 24/05/2023 at 13:48. Pushed by zamundaaa into branch 'master'. backends/drm: always do color management on NVidia GPUs This comes with a small performance hit but ensures that night color works Related: bug 468895 M +1 -1 src/backends/drm/drm_egl_cursor_layer.cpp M +1 -1 src/backends/drm/drm_egl_layer.cpp M +3 -3 src/backends/drm/drm_egl_layer_surface.cpp M +1 -1 src/backends/drm/drm_egl_layer_surface.h M +7 -2 src/backends/drm/drm_output.cpp M +1 -0 src/backends/drm/drm_output.h https://invent.kde.org/plasma/kwin/-/commit/cdafbbbd6f80d6ca0639660ed4ec121754553f54 See also https://github.com/NVIDIA/open-gpu-kernel-modules/issues/162 Actual gamma LUT support shouldn't be too far. Sure, never worked. Even if current Plasma is 5.27.4 Nvidia has just released Gamma LUT support! https://www.nvidia.com/download/driverResults.aspx/214100/en-us/ What changes are required to utilise this rather than the current workaround?

Sorry for the unnecessary spam, it seems it was my fault that it wasn't working, sorry... |
