# 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
|
|
|
|
1. **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.
|
|
2. **SteamOS theme** - the Vapor look of SteamOS for the desktop, with
|
|
**Add to Steam** in right-click menus
|
|
([details](TECHNICAL.md#steamos-desktop-look)).
|
|
3. **Steam Deck/Machine icons** - Steam Deck button icons in gaming mode.
|
|
4. **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](TECHNICAL.md#single-user-mode-sddm-no-locking)).
|
|
5. **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.
|
|
6. **HDMI-CEC** (experimental; off by default, on by default on a Steam
|
|
Machine) - use Steam with your TV's
|
|
remote, and the TV turns on and off with the PC. Needs a PC with CEC (like
|
|
the Steam Machine) or a USB CEC adapter; most graphics cards, NVIDIA
|
|
included, don't have it. See [CEC.md](CEC.md) for which PCs do, and how to
|
|
add it to your own build ([details](TECHNICAL.md#hdmi-cec)).
|
|
|
|
## Steam Machine
|
|
|
|
On a Valve Steam Machine **HDMI-CEC** is ticked by default, as on SteamOS,
|
|
and the menu has two more items:
|
|
|
|
- **Steam Machine support** - the front **LED bar** works, Steam's
|
|
**hardware settings** (fan, performance) work, and the power
|
|
button puts it to sleep like a console.
|
|
- **Pin the kernel to 7.1.6-1** - on by default: with newer CachyOS kernels
|
|
the Steam Machine reboots instead of shutting down. Untick it once CachyOS
|
|
fixes that. The kernel comes from its own
|
|
[release](https://github.com/theupriser/steamify-cachyos/releases/tag/kernel-7.1.6-1),
|
|
checked against CachyOS's signature
|
|
([details](TECHNICAL.md#kernel-pin-steam-machine)).
|
|
- **Update BIOS** - installs Valve's newest Steam Machine BIOS. Never ticked
|
|
by default, at your own risk, and only after two warnings
|
|
([details](TECHNICAL.md#bios-updates-steam-machine)).
|
|
|
|
## 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:
|
|
|
|
```bash
|
|
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`](steamify.sh) (keep the whole folder: it needs
|
|
[`lib/`](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?
|
|
|
|
```bash
|
|
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
|
|
|
|
```bash
|
|
sudo /usr/lib/steamos/steam-set-session plasma.desktop && sudo systemctl restart display-manager
|
|
```
