Linux issues kill Steam Machine sleep function

One of the less remembered but welcome features of the recent consoles has been their ability to enter a sleep state. Like a hibernating PC, this meant that instead of sitting through the boot process every time you returned to a dormant system, it would be ready much more quickly. Unfortunately this isn’t a function that Steam Machines will be able to have, as problems with the way Linux operates have stumped Valve engineers.

Discussing the problems developers faced in a Github bug thread (via Ars) a Valve engineer said that while they had tried hard to make the sleep function work correctly, problems with the way Linux rediscovers plug-in hardware devices like USB controllers, meant that a sleep function just wasn’t possible on the Steam Machines. As one Slashdot commenter pointed out, the problem isn’t suspend, “the problem is resume.”

This is an issue that’s been present with Linux for some time and would require an overhaul of the device management system for input devices for it to be fixed, but that would be a huge job. It’s also not something that needs to be fixed for servers — where Linux is most common. However for a games console, that lack of function is a bother that may be felt by early adopters.

This may mean instead that Valve focuses on giving the Steam machine an exceedingly fast boot time, which would negate much of the need for a sleep function. But of course controlling that might be difficult for Valve since the Steam Machines will have varied hardware configurations. Those with faster CPUs and SS(H)Ds may boot up quickly, but those using more traditional hard drives could find that lack of support frustrating.

Or users may simply opt for a higher energy bill as they leave it on all the time instead.

After using the Legion Go, I’m finally thankful for my Steam Deck

Even since I got my Steam Deck, I’ve spent too much time looking for greener pastures. I wished I could ditch Linux in favor of a more familiar Windows machine. Its enormous form factor left me wanting something a little more portable. Most of all, I yearned for a better display that would match my Nintendo Switch OLED. With each new portable PC that was released, I was sure I’d leave my Steam Deck behind the first chance I got.

I was especially ready to pack it up when I got my Lenovo Legion Go. On paper, it solved almost every problem I had with Valve’s handheld and more. It was much bigger, but with a wildly improved screen; its Switch-like design and Windows integration felt like a perfect fit for what I needed. That’s not to mention that it came with a performance boost too that would theoretically let me play more high-end games that the Steam Deck couldn’t run well.

Half-Life gets a free update and Steam Deck verification for its birthday

Artwork for the original Half-Life's 25th anniversary.

November 19 marks the 25th anniversary of the original Half-Life, and to celebrate, Valve made a special announcement. No, Half-Life 3 was not announced. But Valve celebrated the anniversary with a massive update to the game on PC and a new documentary detailing its development. The best part: It's all available for free.

Half-Life's 25th-anniversary update incorporates the Half-Life: Uplink demo that Valve gave away as a CD via magazine and hardware manufacturer promotions in the 1990s and introduces many multiplayer maps. That includes four brand-new maps -- Contamination, Pool Party, Disposal, and Rocket Frenzy -- and three more maps that were previously only included in the Half-Life: Further Data CD release: Double Cross, Rust Mill, and Xen DM. It's also now possible to play as a Space Biker, Prototype Barney, Skeleton, and Too Much Coffee Man and use dozens of Further Data sprays in Half-Life: Deathmatch.

What reviews didn’t say about the Steam Deck OLED

The Steam Deck OLED on a pink background.

The Steam Deck OLED is a complete refresh of the original model. It packs the same power under the hood, but Valve touched nearly every part of the OLED model to improve on an already stellar design. We have the device in our hands now, and it has a few notable changes that go beyond performance and specs.

Our own Steam Deck OLED review is live, but we wanted to focus in on six unique aspects of the device you wouldn't find in a typical review.
