I have been testing SteamOS on a Minisforum PC equipped with a Ryzen AI 9 370 processor (compensated affiliate link). While much of the attention surrounding this operating system focuses on its console-style interface, there is a functional desktop side that allows for traditional computing tasks.
See the desktop side of SteamOS in my latest video!
The interface is built on KDE Plasma, which offers a layout similar to Windows, including a start menu, taskbar, and file manager. However, the architecture of SteamOS is immutable. This means the operating system is designed to be wiped and replaced during updates. While the user’s files are maintained between updates, system-level modifications, such as kernel drivers or specific VPNs like Tailscale, will not persist after an update without significant technical intervention. This creates a clear boundary between SteamOS and more flexible Linux distributions like Ubuntu or Mint.
For apps, the system relies on the “Discover Store”, which utilizes Flatpaks. These applications run in isolated containers and remain intact through system updates. I found that common applications like Firefox, VLC, and Spotify are readily available. I also installed LibreOffice, which functioned as expected for document and spreadsheet work. While many open-source tools are compatible, high-end professional applications such as DaVinci Resolve are difficult to run due to the specific system architecture and driver requirements.
Another core computing function, printing, is supported on SteamOS. By accessing the system settings, I connected the device to a color laser printer on my network. The installation was straightforward, and the system successfully printed documents from a web browser.
The PC’s 64GB of RAM allowed for an exploration of local AI performance using LM Studio. I loaded a Gemma 4 model to perform image analysis on a photo from my garden. The system identified the objects in the image efficiently, reaching a performance level of 27 tokens per second. While this does not match the speed of a high-end gaming desktop with a dedicated Nvidia GPU, it is a functional level of performance for local AI tasks. It can also serve as a local AI server within a home network, though the aforementioned lack of Tailscale support limits remote access.
For those with game libraries outside of Steam, the Heroic Games Launcher is available through the Discover store. This tool provides access to titles from Epic, GOG, and Amazon Prime. It allows for the configuration of different Proton versions for each game, providing a degree of flexibility for cross-platform libraries.
The transition between the gaming interface and the desktop is handled by a simple toggle. SteamOS is primarily built for gaming appliances, but the desktop environment is sufficient for browsing, office work, and basic media management. And the cool thing is that if you have a Steam Deck, this functionality can essentially turn the Deck into a functional desktop PC when docked.
