How to change primary display or mirror all monitors in Steam Gaming Mode (Bazzite)?
[HELP] Steam Gaming Mode always starts on HDMI screen instead of my TV (DP to HDMI) – Bazzite
Hi everyone,
I’m using Bazzite (Fedora-based) on my PC with three displays:
• One monitor connected via HDMI
• One monitor connected via DisplayPort
• A TV connected via DisplayPort-to-HDMI adapter (I want this to be the main one in Gaming Mode)
In desktop mode, everything is fine.
But when I boot into Steam Gaming Mode, it always starts on the HDMI monitor, and not on the TV I want to use.
The only way to make Gaming Mode display on the TV is to unplug the HDMI cable, which is super annoying.
Here’s what I’ve tried:
• I checked display connections via:
for f in /sys/class/drm/card0-*/status; do echo "$f: $(cat $f)"; done
And it confirms:
• DP-3 is my TV → connected
• HDMI-A-1 is my main monitor → connected
• I edited /etc/gamescope.conf to add:
--prefer-output=DP-3
But Gaming Mode still boots on HDMI-A-1.
• I also confirmed that GAMESCOPE_OUTPUT_NAME is deprecated and --prefer-output is the right way.
I don’t want to unplug cables every time.
Is there a way to force Steam Gaming Mode to always launch on a specific output (my TV = DP-3) without unplugging anything?
Any help or workaround (scripts, configs…) would be appreciated!
Thanks a lot!
