Hey everyone! I’m having trouble getting HDR to work while using Gamescope. I’ve been trying it out with Cyberpunk and Ghost of Tsushima through Steam, but the HDR option in these games is greyed out. I’ve tried various launch options, like –hdr-debug-force-output, but nothing has changed. Here are the specifics of my setup: I’m running Endeavour OS, with an AMD 5800x3d CPU and a Nvidia 3080ti GPU using nvidia-dkms 570.133.07-1. My desktop environment is GNOME 48. Here are the launch options I’m using for Cyberpunk: gamescope -H 1440 -W 3440 -r 240 -f -O DP-1 –adaptive-sync –hdr-enabled — %command% –launcher-skip -skipStartScreen. I’ve also noticed an error when I run Steam from the terminal: [gamescope] [Error] xdg_backend: Compositor released us but we were not acquired. Any help would be greatly appreciated! Let me know if you need any more info. Thanks!

It sounds like you’re trying to run HDR while nested within a desktop environment, which can cause issues. I recommend logging into a TTY (you can do this with Ctrl+Alt+F3 or F4) and launching Gamescope from there. Check out the ‘gamescope-session’ documentation for the right command to use.
That’s not completely true! I run HDR games in Gamescope while on KDE without any issues.
Before launching your game, make sure you’ve enabled HDR in your display settings. According to the Arch Linux wiki, you also need to have the vk-hdr-layer-kwin6-git package installed if you’re using GNOME, which could help resolve this.
Yes, I’ve enabled HDR in the settings and installed that package. Just added more details to my post if you want to check!
I was hoping to run it directly from my DE, but I guess that might be the key issue. Thanks for the tip!
