When I restart the system or put the computer to sleep the night light function is disabled, I need to manually enable it to work again. This is happening while I am using X11, the night color is set to "always on night light" Operating System: Fedora Linux 40 KDE Plasma Version: 6.1.3 KDE Frameworks Version: 6.4.0 Qt Version: 6.7.2 Kernel Version: 6.9.12-200.fc40.x86_64 (64-bit) Graphics Platform: X11 Processors: 4 × AMD Ryzen 3 3200G with Radeon Vega Graphics Memory: 15.3 GiB of RAM Graphics Processor: AMD Radeon RX 550 Series
Does it work on Wayland?

Maybe; I'm afraid there are no guarantees. Virtually all the Plasma and KWin devs are using Wayland full-time now, so fixing X11-specific issues is usually done on an "as resources allow" basis (which is to say, very slowly).
I understand, the Wayland is now a priority, I will try to migrate to it then, thanks for the answer! Regards
Do you have an ICC profile set in colord? Or some other app that modifies screen colors? Unfortunately on X11, many programs will write to the gamma_lut, and we can't guarantee that the night light lut will be set after these other programs
On git master X11, I was able to reproduce this with shutdown and restart or reboot. Wake from sleep worked correctly. - Started in a Wayland session. Set the night light to "always on night light". It turned on as expected. Shut down and booted into X11 - The cursor briefly looked to be in night light colors on the black background. When Plasma loaded, night light was turned off. Night light settings are still set to "always on" - The brightness icon in the system tray shows "Night Light at night color temperature" (which doesn't match the actual color temperature) - Clicking Night Light - Suspend makes the display transition to night light color and then back to day time color. - Un-suspended night light color, put the system to sleep and woke it back up - The login screen was in night light mode, display was correctly in night light mode - Restarted the system - Login screen and system were not in night light mode, same as with a shutdown and start. The night light function was

According to colormgr, I do have an icc profile associated with the laptop display, so it does look like that may be involved. Rodrigo, do you have an icc profile shown with this? colormgr get-devices-by-kind display
Created attachment 172677 [details] Profiles from Color Management hello everyone! I have some profiles in color management, but they are all standard profiles, I've never touched this section before xD

The exact profile doesn't matter, what matters is whether or not (on X11) your display has a profile associated with it
Adding the x11-only keyword
