Set different audio and display in gamemode and desktop? about bazzite HOT 3 CLOSED

Gamescope doesn't have output selection built into the interface and its rules for display selection can be a bit arbitrary at times.
You can:

1. Check your user home .gamescope-stdout.log file (it's a hidden one), which will tell what connector your TV is in. i.e. a graphics card with 3 display ports and 1 HDMI should have DP-1, DP-2, DP-3, and HDMI-A-1. I have a LG TV connected into DP-3 (I use a DP to HDMI adapter) so the log shows drm: Connector DP-3 -> GSM - LG TV SSCR2 for it.
2. Once you know the connector your TV is in, now open in your user home the .gamescope-cmd.log file and copy its contents.
3. In the home folder, go to .config/ (it's a hidden one) and create a folder called environment.d/. Inside it, create a new file called gamescope-session-plus.conf.
4. In our new .conf file, type GAMESCOPECMD=", paste the content you copied from .gamescope-cmd.log, and type another ", so what we just pasted is inside our double quotes wrap. Here is an example:
   GAMESCOPECMD="/usr/bin/gamescope --max-scale 2 --adaptive-sync -e --xwayland-count 2 -O *,eDP-1 --default-touch-mode 4 --hide-cursor-delay 3000 --fade-out-duration 200 --cursor-scale-height 720 -R /run/user/1000/gamescope.yQe3x0S/startup.socket -T /run/user/1000/gamescope.yQe3x0S/stats.pipe"
5. Note from our previous step we have *,eDP-1. Replace it with your connector we checked in the step 1. In my case the final file now is:
   GAMESCOPECMD="/usr/bin/gamescope --max-scale 2 --adaptive-sync -e --xwayland-count 2 -O DP-3 --default-touch-mode 4 --hide-cursor-delay 3000 --fade-out-duration 200 --cursor-scale-height 720 -R /run/user/1000/gamescope.yQe3x0S/startup.socket -T /run/user/1000/gamescope.yQe3x0S/stats.pipe"

Restart the system and whenever you go into game mode it should now select the proper monitor. Desktop mode will retain its own monitor configuration independently.

Gamescope doesn't have output selection built into the interface and its rules for display selection can be a bit arbitrary at times. You can:

1. Check your user home `.gamescope-stdout.log` file (it's a hidden one), which will tell what connector your TV is in. i.e. a graphics card with 3 display ports and 1 HDMI should have DP-1, DP-2, DP-3, and HDMI-A-1.  I have a LG TV connected into DP-3 (I use a DP to HDMI adapter) so the log shows `drm: Connector DP-3 -> GSM - LG TV SSCR2` for it.

2. Once you know the connector your TV is in, now open in your user home the `.gamescope-cmd.log` file and copy its contents.

3. In the home folder, go to `.config/` (it's a hidden one) and create a folder called `environment.d/`. Inside it, create a new file called `gamescope-session-plus.conf`.

4. In our new .conf file, type `GAMESCOPECMD="`, paste the content you copied from `.gamescope-cmd.log`, and type another `"`, so what we just pasted is inside our double quotes wrap. Here is an example:
   `GAMESCOPECMD="/usr/bin/gamescope --max-scale 2 --adaptive-sync -e --xwayland-count 2 -O *,eDP-1 --default-touch-mode 4 --hide-cursor-delay 3000 --fade-out-duration 200 --cursor-scale-height 720 -R /run/user/1000/gamescope.yQe3x0S/startup.socket -T /run/user/1000/gamescope.yQe3x0S/stats.pipe"`

It's great but will it also change audio?

Yup. Gamescope takes control of the DRM and will output audio to the HDMI you have connected or any other device as normal. It's only not possible to output video with one HDMI and audio with another HDMI in the same device (i.e. using to HDMIs from the same graphics card for it).
