Valve's empty, password-less wallet, like SteamOS. The user's wallet is moved aside and restored when single user mode is off; the single user wallet is kept and reused next time.
Steamify CachyOS
Turn a CachyOS desktop PC into a SteamOS-style console: it boots straight into Steam's Big Picture (gamescope), and you can switch to the KDE Plasma desktop and back whenever you like - just like on a Steam Deck or Valve's Steam Machine.
- One command, then a simple checklist: pick what you want.
- Everything is undoable: untick something and it's put back the way it was.
- Made for the Steam Machine, and works on any CachyOS KDE desktop PC.
What you get
- SteamOS conversion - boots straight into gaming mode. Switch to
Desktop in Steam works, and so does going back (the Return to Gaming
Mode icon on the desktop). Steam's on-screen keyboard (Steam + X) works
on the desktop too.
- Boot into: gamescope / desktop - where the PC starts. Gaming mode is the default.
- SteamOS theme - the Vapor look of SteamOS for the desktop, with Add to Steam in right-click menus (details).
- Steam Deck/Machine icons - Steam Deck button icons in gaming mode.
- Single user mode - like SteamOS: never a login or lock screen, and no KDE wallet password prompts (e.g. from Brave). Typing a password with a controller is no fun (details).
- Steamify shortcut - an icon on the desktop and in the launcher that opens the newest Steamify, so you don't need the install command again.
Steam Machine
On a Valve Steam Machine the menu has two more items:
- Steam Machine support - the front LED bar works, Steam's hardware settings (fan, TV control over HDMI-CEC) work, and the power button puts it to sleep like a console.
- Update BIOS - installs Valve's newest Steam Machine BIOS. Never ticked by default, at your own risk, and only after two warnings (details).
Requirements
- CachyOS with the KDE Plasma desktop (the default CachyOS Desktop edition)
- Your normal user account, with permission to use
sudo
Installation
Open Konsole on your Plasma desktop and run:
curl -fsSL https://github.com/theupriser/steamify-cachyos/releases/latest/download/steamify.sh | bash
Prefer to look at the script first? Clone the repository and run
./steamify.sh (keep the whole folder: it needs
lib/).
You'll see a checklist:
[x] SteamOS conversion: boot into gaming mode, Steam on the desktop (now: off)
└ Boot into: [gamescope] desktop
> [x] Install SteamOS theme: Vapor look (cachyos-vapor) (now: off)
[x] Install Steam Deck/Machine icons: Deck button icons in gaming mode (now: off)
[x] Single user mode: no password, lock screen or log out (SDDM) (now: off)
[x] Steamify shortcut: desktop icon to run this again (now: off)
Up/Down move Space select Left/Right choose Enter run
a run + re-apply what's on q quit
Tick with Space, run with Enter. It shows what it will change, asks your password once, and offers to restart at the end. Below the list you see every installed kernel, so after an update it's easy to check that everything is in place.
Run it again whenever you like: to change your choices, or after a CachyOS
update (press a to re-apply what's on).
Using it
- To the desktop: in gaming mode, open the Steam menu and choose Power > Switch to Desktop.
- Back to gaming mode: double-click Return to Gaming Mode on the desktop.
- Remove it all: run the wizard and untick everything. You get the normal CachyOS login screen back; Steam stays installed.
Prefer to start where you left off last time?
steamos-session-select persistent # start where you left off last time
steamos-session-select oneshot # always start in gaming mode (default)
Something wrong?
Stuck on a black screen in gaming mode: press Ctrl+Alt+F3, log in, and run
sudo /usr/lib/steamos/steam-set-session plasma.desktop && sudo systemctl restart display-manager
