you don't, why would you? use kde they have built in stuff for this... you said you use bazzite
https://docs.bazzite.gg/Handheld_and_HTPC_edition/quirks/#how-do-i-specify-the-correct-monitor-for-gaming-mode-to-use-htpc-only
Documentation is incorrect as well. Xrandr doesn't even return full device names. You need to know to append the Linux HDMI naming convention. You also need to fuck with pulse wire on DE and gaming mode. I've run into similar issues in Debian including have to fuck with pulse wire for HDMI audio.
But I'm sure it's just my distro. I bet mint will work flawlessly 🙄
the documentation doesn't say to use xrandr to do that, it gives clear instructions you didn't follow.
Sorry you've got me. I mixed up Gnome and the generic.
