No that is specific to Arch, as far as I understand the gamescope that ships with Bazzite can basically do the same thing.
My latest command is
gamescope --hdr-enabled --hdr-itm-enabled --fullscreen -W 3840 -H 2160 -r 160 --force-grab-cursor --adaptive-sync --steam -- env DXVK_HDR=1 MANGOHUD=1 bazzite-steam -tenfoot
Basically what you have, though I am using bazzite-steam versus steam. Though to be honest I am drawing a blank what the difference is.
No idea what enc is, I don’t have it on my path either. But it sounds like it still launches afterwards, if I am reading you right, so it may be red herring.
You may get more eyes on this in it’s own thread, as it seems like you are hitting a distinct error situation.
Games I’ve confirmed HDR on for reference:
- Silent Hill 2
- Hunt Showdown
- Lies Of P
I really haven’t gone much deeper then that because I can’t only really play gamepad games due to mouse being completely messed up under gamescope.
