Since Plasma 6.2, the HDR toggle has disappeared from the system settings page for my monitor. It was there under 6.1. ![image](https://discuss-cdn.kde.org/uploads/default/original/2X/8/824b78a434e1ae1459c44a971d914866dd25934b.png) kscreeen-doctor shows HDR: disabled on this monitor (I know my second monitor is incapable of HDR). ```auto [solarisfire@solaris-arion udpSender]$ kscreen-doctor -o Output: 1 DP-1 enabled connected priority 1 DisplayPort Modes: 1:3840x1080@120! 2:5120x1440@120* 3:5120x1440@100 4:5120x1440@60 5:3840x1080@100 6:3840x1080@60 7:2560x1440@60 8:2560x1080@120 9:2560x1080@100 10:2560x1080@60 11:2560x1080@60 12:1920x1080@120 13:1920x1080@100 14:1920x1080@60 15:1920x1080@60 16:1680x1050@60 17:1600x900@60 18:1280x1024@75 19:1280x1024@60 20:1440x900@60 21:1280x800@60 22:1152x864@75 23:1280x720@60 24:1024x768@75 25:1024x768@70 26:1024x768@60 27:800x600@75 28:800x600@72 29:800x600@60 30:800x600@56 31:640x480@75 32:640x480@73 33:640x480@60 Geometry: 0,1011 5120x1440 Scale: 1 Rotation: 1 Overscan: 0 Vrr: Automatic RgbRange: unknown HDR: disabled Wide Color Gamut: incapable ICC profile: none Color profile source: EDID Brightness control: supported, set to 30% Output: 2 DP-2 enabled connected priority 2 DisplayPort Modes: 34:2560x1440@60! 35:2560x1440@144* 36:2560x1440@120 37:2560x1440@100 38:2560x1440@85 39:2560x1440@24 40:1024x768@60 41:800x600@60 42:640x480@60 Geometry: 5120,0 1440x2560 Scale: 1 Rotation: 2 Overscan: 0 Vrr: Automatic RgbRange: unknown HDR: incapable Wide Color Gamut: incapable ICC profile: none Color profile source: EDID Brightness control: supported, set to 30% ``` ---

Same thing for me, but I haven’t updated since 6.2 was available on Arch, and just noticed it is missing. ---

Holy… And I thought it is because it is still worked on the brightness control that the appearance slightly changed, but in reality it is HDR that is off. kscreen-doctor reports in my case `HDR: enabled` for the particular Monitor that I had it enabled in the past, but just checked my monitors OSD and that tells me otherwise (HDR: OFF) ---

Same issue here on Manjaro running plasma-desktop 6.2.1-1. No HDR toggle in settings anymore and `kscreen-doctor -o` initially said disabled. I ran `kscreen-doctor output.DP-2.hdr.enable` from the docs and it now says enabled but the option is still not visible in the Settings app after a reboot. ```auto Output: 1 DP-2 enabled connected priority 1 DisplayPort Modes: 1:3440x1440@60! 2:3440x1440@175* 3:3440x1440@144 4:3440x1440@120 5:3440x1440@100 6:1024x768@60 7:800x600@60 8:640x480@60 Geometry: 0,0 3440x1440 Scale: 1 Rotation: 1 Overscan: 0 Vrr: Automatic RgbRange: unknown HDR: enabled SDR brightness: 200 nits SDR gamut wideness: 0% Peak brightness: 1060 nits Max average brightness: 254 nits Min brightness: 0 nits Wide Color Gamut: incapable ICC profile: none Color profile source: sRGB Brightness control: supported, set to 100% ``` Monitor OSD still reports HDR being off however as noticed by M.Karrde. ---

The toggle was intentionally removed for NVidia users, because of a very severe driver bug that reportedly blocked a lot of people from even logging in after they enabled HDR. You can enable it again by putting `KWIN_DRM_ALLOW_NVIDIA_COLORSPACE=1` into /etc/environment and rebooting Note that you may experience that driver bug as well; if you do, removing that environment variable and rebooting should allow you to log in again. ---

Would it not have been better to leave the HDR toggle in place, but leave it greyed out to show it’s disabled, and had a tool-tip explaining the reasoning behind it? ---

Sure, but this is a driver bug we quickly worked around. I didn’t intend to spend any more time on driver bugs than necessary; hopefully NVidia fixes it soon and we can just remove the workaround again. ---

I dare say the 555/560 linux drivers are so broken (still, after nearly a year), particularly with KDE/Wayland, you might as well just warn users up front it simply won’t work right if they have Nvidia. ---

Nvidia 560.35.03 (With a GTX 3090) with KDE Plasma & Wayland have been working pretty darn perfectly for me the last few months actually 😅 I thought Nvidia users were going to be stuck on X11 forever, but explicit sync really fixed things. ---

Well that’s literally what I was hoping for, working Wayland for gaming, upgrading to Plasma 6.0 back in Jan/Feb time, and with 550 drivers it was still a hot mess of flickering for a large amount of apps let alone gaming with Steam Proton. I learned about the explicit sync mess and just stayed on x11, which I still am today. I had hope for 555 fixing this, but watching the nvidia linux driver threads it seemed to break more than it fixed, particularly related to KDE and Proton/Wine games, and before even fixing that full 560 got dumped out to much of the same with all the old broken things plus more new. The threads [here](https://forums.developer.nvidia.com/t/555-release-feedback-discussion/293652/270) and [here](https://forums.developer.nvidia.com/t/560-release-feedback-discussion/300830/545) are still full of lots of broken users and few nvidia answers. I suppose it’s probably different for everyone, and every distribution but using Arch, Plasma6/6.1, proton/wine, complaints seemed to match my general use case to simply avoid like the plague until I see some actual positive feedback. Now I’m just looking for a new laptop (with AMD). Yours is I think the first I’ve seen of _anything_ positive for 560 in linux. What distribution are you using? ---

All arch. I install the drivers manually with the nvidia-all tool ([GitHub - Frogging-Family/nvidia-all: Nvidia driver latest to 396 series AIO installer](https://github.com/Frogging-Family/nvidia-all)). DKMS - Using the Open source kernel modules. I have both the mainline and lts kernels and it works on both. I sit on mainline until I find something broken. I have: GRUB\_CMDLINE\_LINUX\_DEFAULT=“loglevel=3 nvidia\_drm.modeset=1 nvidia\_drm.fbdev=1 nowatchdog quiet splash” in my /etc/default/grub config. Plasma 6.2.1 And I play steam games using proton all day long just as well as I would on Windows. ---

It also works fine for me using the same kernel parameters(nvidia\_drm.modeset=1 nvidia\_drm.fbdev=1) and manjaro with the 560 driver. I have a 4090 Operating System: Manjaro Linux KDE Plasma Version: 6.2.1 KDE Frameworks Version: 6.7.0 Qt Version: 6.8.0 Kernel Version: 6.11.4-1-MANJARO (64-bit) Graphics Platform: Wayland Processors: 32 × AMD Ryzen 9 7950X3D 16-Core Processor Memory: 30.5 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 4090/PCIe/SSE2 Manufacturer: Gigabyte Technology Co., Ltd. Product Name: X670E AORUS PRO X System Version: -CF Before the update I was able to use HDR no problem. 6.2.1 has actually made things worse for me by disabling HDR and the stupid akonadi\_migration\_agent notfication that never goes away. `KWIN_DRM_ALLOW_NVIDIA_COLORSPACE=1` added to /etc/environment does nothing ---

Hey there, this solution worked to show the toggle again on my system. However there’s a bug with it that may have been overlooked. My HDR was enabled Prior to the update to KDE 6.2, and then the toggle was removed afterwards, but HDR was still enabled. You may want to ensure HDR get’s disabled afterwards if there are bugs with it. Thanks! ---

> [@CypherColt](#): > > HDR was still enabled Are you sure? While KDE/kscreen-doctor claimed enabled, my Monitor (OSD) and the screen appearance told me disabled for sure. Not to mention that if that bug is potentially triggered by enabling HDR, people that have already successful enabled HDR without triggering the bug would be fine, as shown by my now working HDR, I guess. ---
