To enable Syncthing GTK in game mode, you will need to create a new text file located in /home/deck/.config/systemd/user/

Create a text named “syncthing.service” and the contents of the file will be:
[Unit]
DescriptionSyncthing
[Service]
Typesimple
ExecStartflatpak runs –commandsyncthing me.kozec.syncthingtk
Reboot Failed
RestartSec1
SuccessExitStatus3 4
[Install]
WantedBydefault.target

Then open Konsole and run the commands:
systemctl –user enable synchronization
systemctl –user starts synchronization

If you want to disable Syncthing upon launch, you can run the following commands:
systemctl –user stops synchronization
systemctl –user disable synchronization
