Solution

  1. Switching Accounts:

    • Start by logging into a new Steam account through the game interface.

    • If the switch is successful, proceed to delete all files (excluding folders) located in Home/.local/share/kscreen and Home/.local/share/kscreen/outputs.

    • After backing up, switch back to the game mode, log into the original account that was experiencing issues, and try switching to desktop mode again. The problem should now be resolved.
  2. For Users with Decky Extension Framework Installed:

    • Ensure that you have the Decky Extension Framework installed and have set up a root password beforehand.

      cd /home/deck/.local/share/kscreen rm * cd /home/deck/.local/share/kscreen/outputs rm * exit
    • After executing these commands, close the Terminal and attempt to enter desktop mode again; the issue should be fixed.
    • It's recommended to create a script file named fix.sh containing the above commands and store it in /home/deck/.Remember to make the script executable with the command sudo chmod +x /home/deck/fix.sh.
