Gaming

System-packaged steam

Many people prefer to install Steam as a system package rather than using Flatpak. We have integrated it into our Steam gaming system extension. Enable it via:

updatectl enable --now --reboot steam-gaming

Gaming Mode (steamos inspired)

Caution

The gaming mode is still experimental, so some features, such as session switching, may not work as smoothly as you are used to on the Steam Deck. We plan to integrate it more deeply with cosmic(-greeter) in the future.

We provide a Steam Gamescope session in the aforementioned extension. Install and select it in Cosmic Greeter:

Auto login into Gaming Mode

Note

We plan to make this easier in future.

Caution

Enabling autologin of any kind reduces your system’s security. However, this is acceptable for a machine that is primarily used for gaming.

We need to manually edit Cosmic Greeter’s configuration file:

sudo vim /etc/greetd/cosmic-greeter.toml

Add the following section:

[initial_session]
command = "gamescope-session-plus steam"
user = "<your-username>"

Substitute <your-username> with your actual username.
