Preparation #

Mostly, we config our Steam Deck in Desktop Mode, so I highly recommend you connect your device with a USB Hub , then connect your mouse and keyboard . Bluetooth keyboard and mouse are also good.

If you don’t have external mouse and keyboard besides you, just use the buttons.

This is a part of key mappings.

By this way, you can directly control your device in Desktop Mode, but it’s a little bit inconvenient.

If you feel hard to operate Deck using buttons, you may enable Remote Desktop. See: Enable Remote Desktop.

Environment #

Do it first #

Add password to current user #

In Desktop Mode, open Konsole, and add a password to current user, for sudo use.

passwd

# New password:
# Your input will not appear, please make sure your input is correct, then push ENTER.

Disable steamdeck-readonly #

# disable
sudo steamos-readonly disable

# enable(if you want to enable it again after config.)
sudo steamos-readonly enable

Recommended Options #

Change Desktop Mode Language #

You can choose your language in Desktop Mode, follow the guide in KDE UserBase Wiki: https://userbase.kde.org/Tutorials/Change_Plasma_Language

Config Flatpak #

For most users, you can skip this part. This part is for users who have trouble searching apps in Discover, mainly for users in China.

If your Discover searching has no response, please change the remote mirror.

# This will overwrite the official mirror link.
sudo flatpak remote-modify flathub --url=https://mirror.sjtu.edu.cn/flathub

# If you don't want to overwrite, you can add a mirror link.
sudo flatpak remote-add flathub https://mirror.sjtu.edu.cn/flathub/flathub.flatpakrepo

Install a browser #

Some plugins may depend on browser to setup, so a browser is needed. You can install any browser you are favorite. Directly install it through Discover.

Enable Remote Desktop #

Steam Deck uses KDE Plasma desktop, we can use krfb to start a remote desktop service.

We need to install krfb on Deck, then we can use VNC protocol to remote connect our device in Desktop Mode.

sudo pacman -Sy krfb

If you can't install pacman packages because of unknown trust, please do:

# Step 1
sudo pacman-key --init

# Step 2
sudo pacman-key --populate archlinux
sudo pacman-key --populate holo

Then, re-run your command.

Now you can use your VNC Client to connect to the Deck. Default port: 5900.

VNC Client #

For Windows users, VNC Viewer is an option.

The app in the picture below is Royal TSX.

Customizations #

AUR #

If you want to install AUR(Arch User Repository) packages, please install an AUR helper.

base-devel is needed in most cases.

# Install base-devel
sudo pacman -S base-devel

# Install AUR helper
sudo pacman -Sy paru
# or
sudo pacman -Sy yay
# etc...

Localsend #

Wirelessly transfer files in local network.

AUR helper is required!!!

paru -Sy localsend-bin
# or yay -Sy

Google Chrome #

Directly install it through Discover.
