Currently, we advise against attempting a SteamOS installation.
Valve is distributing an initial alpha build, which has specific, and somewhat limited, hardware prerequisites.
Furthermore, the installation procedure has not yet been fully optimized for ease of use.
The process remains relatively complex at this stage of development.
SteamOS: A Comprehensive Overview
SteamOS represents Valve’s initiative to develop a PC gaming operating system founded on Linux. Its primary purpose is to power Steam Boxes, which are essentially PCs tailored for use in a living room environment.
The concept behind Steam Boxes – also known as Steam Machines – and SteamOS is to offer a direct challenge to established console systems such as Xbox, PlayStation, and Nintendo consoles.
These systems aim to deliver the versatility and power of PC gaming directly to the television, providing a different experience than traditional consoles.
Foundation in Linux
Being built upon the Linux kernel, SteamOS ensures compatibility with games already available on the Steam for Linux platform. This means titles verified to run on Steam for Linux will also function seamlessly within the SteamOS environment.
A key aspect of SteamOS is its free availability. Users are empowered to download and install the operating system on their existing computer hardware, offering a cost-effective entry point.
Furthermore, SteamOS embraces the open-source nature of Linux, allowing users to freely modify the system and its software components, mirroring the flexibility of traditional Linux distributions.
Strategic Implications for PC Gaming
Valve’s development of SteamOS is a strategic move to lessen the PC gaming industry’s reliance on Microsoft Windows. It aims to establish a viable alternative within the living room gaming space.
The growth of Linux as a gaming platform provides the PC gaming industry with a potential safeguard. This safeguard would be useful if future iterations of Windows were to become overly restrictive or eliminate desktop functionality.
SteamOS, therefore, isn’t just an operating system; it’s a long-term investment in the future of PC gaming and its independence.
SteamOS and the Big Picture TV Experience
Users unfamiliar with Linux need not be apprehensive about SteamOS. For the average gamer, the operating system will be pre-loaded onto Steambox hardware, specifically tailored for optimal performance. Simply connect the device to your television and power it on; it’s designed for immediate usability.
The primary interface encountered will be Steam’s “Big Picture Mode,” which has been refined for navigation using a game controller. This provides a streamlined, TV-friendly experience.
Flexibility in Installation
While designed for Steambox, SteamOS installation isn't restricted to specific hardware. It can be installed on a variety of systems. Notably, Big Picture Mode is also compatible with Windows, macOS, and other Linux distributions.
This allows any computer running Steam to function effectively as a set-top box connected to a television, expanding the possibilities for home entertainment.
Foundationally Rooted in Debian Wheezy, Distinct from UbuntuWhile Valve directs users towards Ubuntu for Steam installations on Linux, the core of SteamOS is actually constructed upon Debian Wheezy. Valve addresses the inquiry regarding the choice of Debian over Ubuntu within the SteamOS FAQ section.
"Leveraging the Debian foundation provides Valve with the optimal pathway to furnish a completely tailored SteamOS experience for our user base."
However, this explanation doesn't fully elucidate the rationale. Speculatively, Debian's deliberate pace and inherent stability likely contribute to its selection as a foundational system. Ubuntu, conversely, undergoes more frequent updates and has initiated potentially disruptive system modifications, notably Mir.
Mir represents Ubuntu’s independent effort to supersede Xorg with a proprietary display server. The broader Linux community, however, appears to be converging on Wayland as the standard. This divergence positions Ubuntu as a unique developer of its own graphical display infrastructure.
The close relationship between SteamOS and Debian is evident in the fact that the SteamOS installer is essentially a modified iteration of the Debian installer. Furthermore, the system includes Iceweasel, a rebranded version of the Mozilla Firefox web browser, devoid of original branding.
The selection of Debian provides a solid and predictable base for SteamOS development.
The GNOME-Based Linux Desktop Environment
The SteamOS operating system utilizes a standard GNOME 3 Linux desktop as its foundation, incorporating the GNOME Shell interface. Accessing this desktop environment is straightforward.
Navigate to the Steam settings panel, then find the Interface section. Within this menu, activate the feature labeled "Enable access to the Linux desktop."
Once enabled, a "Return to Desktop" option becomes available, allowing you to switch from the SteamOS environment to the underlying Linux desktop.
Switching Between Interfaces
To revert back to Steam's TV-optimized user interface, simply select the "Return to Steam" icon. This provides a seamless transition between the two environments.
The underlying system is a fully functional Linux distribution, offering users the flexibility to explore beyond the SteamOS gaming experience.
SteamOS Leverages APT for System Updates and Software Installation
APT, originally created by Debian and also utilized by Ubuntu, serves as the package manager for SteamOS.
Valve maintains its own software repositories, and SteamOS is designed to automatically update system packages sourced directly from these repositories.
Expanding Software Availability
While SteamOS initially includes only Valve’s repositories, users retain the capability to integrate additional package sources.
This functionality allows the SteamOS community to potentially establish their own repositories, broadening the range of accessible Linux desktop software.
Future Plans and Compatibility
Valve intends to expand the selection of packages available directly through the SteamOS software repositories in the future.
Currently, a significant degree of compatibility exists with Debian Wheezy packages.
It is important to understand how software installation & package managers work on Linux to fully utilize SteamOS.
SteamOS and 32-Bit CompatibilityCurrently, SteamOS possesses demanding hardware prerequisites. A 64-bit processor and Unified Extensible Firmware Interface (UEFI) are essential, precluding systems with legacy Basic Input/Output System (BIOS) firmware.
Despite these initial constraints, anticipation exists regarding broadened hardware support from Valve in the future.
32-Bit Software Repositories
Valve maintains 32-bit software repositories specifically for SteamOS. This indicates potential development towards a 32-bit version of the operating system.
The availability of such a version would significantly enhance compatibility with older computer hardware currently unable to run SteamOS.
- A 32-bit SteamOS release would broaden the user base.
- It would allow users to utilize existing hardware.
