TUXEDO OS is a Linux distribution developed by TUXEDO Computers. It is based on Ubuntu LTS, uses the KDE Plasma desktop, ships with Flatpak support, and includes TUXEDO-specific optimizations while remaining installable on most standard PCs and laptops.

1. Before you Start

Minimum Requirements

Recommended Hardware

• 64-bit CPU (Intel or AMD)
• 4 GB RAM minimum (8+ GB recommended)
• 25 GB free storage minimum
• UEFI firmware
• USB flash drive (8 GB or larger)

Important Notes

• Secure Boot should be disabled before installation. TUXEDO explicitly notes this requirement for ISO installations.
• NVIDIA GPUs generally work well, but very new GPU generations may occasionally require post-installation driver updates.

2. Download the TUXEDO OS ISO

Download the latest ISO image from:

Official TUXEDO OS Download Page

After downloading:

Linux

sha256sum TUXEDO-OS*.iso

Windows

Get-FileHash .\TUXEDO-OS.iso -Algorithm SHA256

Verify the checksum against the value provided by TUXEDO.

Verify:

flatpak --version

Add Flathub:

Install software:

flatpak install flathub org.videolan.VLC

11. Configure Drivers

AMD Graphics

Normally automatic.

Verify:

lspci | grep VGA

Normally automatic.

No action needed.

NVIDIA Graphics

Check:

nvidia-smi

If not installed:

sudo ubuntu-drivers autoinstall

or use:

sudo apt install tuxedo-nvidia-driver

depending on available repositories.

Some users with very recent NVIDIA hardware have reported needing manual driver installation after setup.

12. Install Essential Software
