Hi,
I would like to achieve something similar to the game mode of SteamOS but in a free and open source manner, i dont have a Steam Deck but i watched youtube videos on how it works and there are two separate modes, you have the game mode and the desktop mode i would like to achieve the same results on my Manjaro distro.
I dont know exactly how to achieve this but i have read how Valve does this and it has something to do with gamescope now i installed opengamepadui-bin which also automatically installs gamescope i also installed as optional firejail, powerstation and brightnessctl which i think you probably also need.
I would like to explain what i want to achieve the game mode would be similar to game mode of SteamOS but instead of loading up the Steam UI it should load up OpenGamePad UI instead and when you want to return to desktop mode it should work just like in SteamOS and it should return me to the Manjaro KDE desktop environment.
Can anybody please tell me which steps i should take to achieve this?
greetings
