[kwin] [Bug 480648] Display Stuck in HDR After Disabling HDR
https://bugs.kde.org/show_bug.cgi?id=480648 Zamundaaa changed: What|Removed |Added Resolution|--- |UPSTREAM Status|REPORTED|RESOLVED --- Comment #14 from Zamundaaa --- Switching between applications that control the screen with different capabilities is a more general issue in Linux; if you run SDDM with Xorg, Xorg simply doesn't understand HDR, and that includes not understanding how to turn it off. If you run SDDM on kwin_wayland, that issue will go away. As for the other issues, as long as drm_info tells you the correct properties are being set, KWin is doing everything correctly. Please report them to your driver vendor; with AMD the right place for that would be https://gitlab.freedesktop.org/drm/amd/-/issues and with NVidia https://github.com/NVIDIA/open-gpu-kernel-modules/issues -- You are receiving this mail because: You are watching all bug changes.

Like when I log out of Plasma, HDR should be disabled or there should be a signal to the monitor that the following content is no longer HDR. -- You are receiving this mail because: You are watching all bug changes.

It works fine in Windows. I also have 2 Gigabyte m28u monitors that switch correctly on Linux. HDR set in Plasma: Colorspace: BT2020_RGB, HDR_OUTPUT_METADATA: 144 HDR disabled in Plasma: Colorspace: Default, HDR_OUTPUT_METADATA: 0 Monitor mode makes no difference in drm_info Colorspace/HDR_OUTPUT_METADATA Plasma 6.0.2 Arch Linux Kernel 6.8.1-zen1-1-zen -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=480648 --- Comment #7 from theriverle...@gmail.com --- 6.7.2 I ordered another adapter to try tomorrow, so we'll see if that's any different. The reason I filed a bug report is that HDR switching works perfectly on Windows, although I noticed that DSC is enabled by default and I have no idea how to force enable it on Linux. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=480648 --- Comment #6 from Zamundaaa --- Okay, KWin is correctly setting HDR_OUTPUT_METADATA to 0 and Colorspace to Default, so this is either the display behaving funky and needing HDR_OUTPUT_METADATA that tells it to turn off HDR explicitly, or it's a driver bug.
