• All the benefits of Bazzite, Universal Blue and Fedora Atomic.
• 4 choices of Desktop Environments (Cosmic, XFCE, KDE and Gnome) instead of just 2 (KDE/Gnome)
• Windows 7 theme included in KDE (AeroThemePlasma)
• Windows XP theme included in XFCE (slightly tweaked xfce-winxp-tc)
• Gnome pre-configured with extensions
• Windows-like configuration for Cosmic
• Always have the latest version of Cosmic thanks to the ryanabx/cosmic-epoch copr repo
• Firefox replaced by LibreWolf (with user-friendly settings applied)
• Firefox Gnome theme and compact extensions panel from firefox-csshacks applied by default with auto-updates
• Replaced Lutris with a custom build of Heroic Games Launcher that fixes console mode.
• Have an android phone? ADB, scrcpy and Universal Android Debloater are included in ShadowOS
• ujust scrcpy-cam command included if you want to use your phone's camera as your camera (you might want to run ujust scrcpy-cam edit first)
• ujust toggle-autologin command included in Cosmic/XFCE variants if you prefer to auto-login into your desktop (KDE/Gnome should have the option in settings)
• Replaced Bazaar with Gnome Software (Cosmic Store in the Cosmic variant)
• Run MangoHUD in any game out-of-the-box just by pressing the END key
• Automatic DLSS upgrades in all games

You can download the latest ISO file from:

• The official website*
• The 'Actions' page

*credits to nightly.link for allowing artifact downloads without needing an account

Rebase

Warning

This is an experimental feature, try at your own discretion.

First, make an environment variable for the variant of your choice

First, pick a desktop environment:

Cosmic (Recommended)

DE=linux

Gnome

DE=gnome

KDE

DE=kde

XFCE

DE=xfce

Then, select your gpu:

AMD/Intel

GPU=

NVIDIA (GTX 16xx and RTX series)

GPU=-nvidia

NVIDIA Legacy (GTX 745 and later)

GPU=-nvidia-legacy

After that, choose if you would like steam or not:

Steam

STEAM=-steam

No Steam

STEAM=

Then, run this command:

VARIANT="shadowos-${DE}${GPU}${STEAM}"

After that, either:

Rebase an existing atomic Fedora installation to the latest build

• Rebase to the unsigned image, to get the proper signing keys and policies installed:

  rpm-ostree rebase ostree-unverified-registry:ghcr.io/shadowos-linux/$VARIANT:latest
  

• Reboot to complete the rebase:

  systemctl reboot
  

• Then rebase to the signed image, like so:

  (source /etc/os-release && rpm-ostree rebase ostree-image-signed:docker://ghcr.io/shadowos-linux/$VARIANT_ID:latest)
  

• Reboot again to complete the installation

  systemctl reboot
  

Rebase an existing ShadowOS Linux installation to another variant

rpm-ostree rebase ostree-image-signed:docker://ghcr.io/shadowos-linux/$VARIANT:latest

Verification

These images are signed with Sigstore's cosign. You can verify the signature by downloading the cosign.pub file from this repo and running the following command:

cosign verify --key cosign.pub ghcr.io/shadowos-linux/shadowos-linux

Disclaimer

Warning

I prohibit the usage of this software in areas where age verification is required by law.

I am therefore not responsible if you downloaded ShadowOS Linux in those areas.
