Games: Valve's Steam Deck and futex2

Filed under
  • Valve has revealed a lot more about the Steam Deck in recent weeks, and here are 10 more things that you should know before buying the console.

    Valve’s latest Steam Deck is a promising piece of hardware and is showcasing some great potential for the future of the company’s hardware offerings. A lot has already been talked about at length when it comes to Steam Deck, but it’s understandable that fans may still have some lingering questions before they decide to plop upwards of $399 for the hardware.

    Luckily, recent developments on the matter have cleared the air surrounding the hardware and software with Valve seemingly giving out hardware units to developers for testing purposes. Furthermore, Valve’s recent interviews and press releases have revealed more about the Steam Deck, so here are 10 more new things you need to know before buying the console.


    As mentioned earlier, the Steam Deck will use Proton API to run Steam games that aren’t native to Linux.

  • Better Linux Gaming With Steam and Proton | Tom's Hardware

    If you're at all interested in gaming on PCs, you’ve probably come across Steam, Valve’s platform for distributing, updating and running games. Steam makes it possible to purchase a game, install it over the internet and then run it from the Steam interface. Ah, but that brings us back to the age-old Linux gaming conundrum of support, as not every PC game is designed to run on anything other than Microsoft Windows.

    That said, there are plenty of Steam games that will run on Linux, and quite often, a Windows Steam game can be convinced to run on Linux even though some ‘fettling’ by the user may be required. This approach is officially supported by Steam using a system called Proton. Getting all of these things running, and then possibly optimising the results, is what we’ll be looking at in this tutorial.

  • Looks like the important futex2 work is finally going into the Linux Kernel to help gaming | GamingOnLinux

    After a long bumpy road with many revisions, it appears that the futex2 work sponsored by Valve is finally heading into the upstream Linux Kernel. Initially much larger, the work was slimmed down to get the main needed parts done and enabled before the rest can make it in.

    So what is it? As developer André Almeida previously described it: "The use case of this syscall is to allow low level locking libraries to wait for multiple locks at the same time. This is specially useful for emulating Windows' WaitForMultipleObjects. A futex_waitv()-based solution has been used for some time at Proton's Wine (a compatibility layer to run Windows games on Linux). Compared to a solution that uses eventfd(), futex was able to reduce CPU utilization for games, and even increase frames per second for some games. This happens because eventfd doesn't scale very well for a huge number of read, write and poll calls compared to futex. Native game engines will benefit of this as well, given that this wait pattern is common for games.".

ScummVM: Twenty years ago today...

Filed under

Twenty years ago today, on Tue Oct 9 16:30:12 2001, Ludvig Strigeus pushed the initial revision of the ScummVM code, which was version 0.0.1 of the project. Time flew quickly and, fast-forward to the present day, we are proudly releasing ScummVM 2.5.0 “Twenty years ago today…”

The list of changes is tremendous.

First of all, this is the first release that supports 2.5D games (almost 3D), thanks to the merger with ResidualVM. With this release we announce support for Grim Fandango, The Longest Journey and Myst 3: Exile. This is why we jumped straight to 2.5 in our versioning. Please note that only desktop platforms currently support these games and other platforms may or may not gain the support later depending on their capabilities.

  • RC model flying simulator Wings is now available for Linux | GamingOnLinux

    While celebrating the first anniversary of their game, Kitchen Sink Games have released a Linux version of their RC model flying simulator Wings.

    Not one we've been able to try yet so here's what the developers say: "Wings let you experience the thrill of RC model flying from the comfort of your own home. The perfect training tool for learning to fly, or to enhance your racing skills. With online multiplayer and offline modes. We think this is the best online flight simulator experience.".

  • Closed Hands is a deep work of interactive fiction following a terror attack | GamingOnLinux

    Closed Hands is an experimental work of interactive fiction from PASSENGER, it's recently jumped over from to Steam. For the Steam release it comes with some exclusive extras like a developer commentary, a full soundtrack, an ebook of the story and access to a library of original artwork, sketches, and example Ink scripting files.

    The story follows the lead-up and aftermath of a terror attack in a fictional UK city, as you follow five main characters. With the gameplay progressing through a free-form fragmented narrative, it allows you to make your own path through the story with it going backwards and forwards in time. Part of the aim is to "challenge wider preconceptions users have about video game storytelling" and help players "understand the complex effect extremism has on people’s perceptions of cultures and communities".

  • Kröwns and Daggers is another big free upgrade for Northgard out now | GamingOnLinux

    Kröwns and Daggers expands the ties between clans while also adding in a whole new neutral faction to Northgard.

    Featuring a new Diplomacy screen that blends together all new interactions with both clans and neutral factions. If you want to improve relations with neutral factions you can now build an offering well, Dwarves have entered the lands as the new additional neutral faction and even new spying mechanics.

  • Nickelodeon All-Star Brawl Review - Boiling Steam

    Nickelodeon All-Star Brawl (NASB) is a Super Smash Bros.-style platform fighter for Steam, Xbox, PlayStation, and Nintendo Switch. It’s developed in collaboration with Ludosity — the folks behind Slap City — and Fair Play Labs, published by GameMill Entertainment. Duke it out as one of your favorite Nickelodeon characters, ranging from shows you may have watched in the 90s to some of the modern day shows — Spongebob and Patrick from Spongebob Squarepants, Ren & Stimpy from the somewhat controversial show bearing the same name, Helga from Hey Arnold!, Reptar from Rugrats, Zim from Invader Zim, Aang from Avatar: The Last Airbender, CatDog from said show, among many others.

  • Try out the new demo for the RTS game TFC: The Fertile Crescent on Steam | GamingOnLinux

    Available now until at least the end of EGX on October 10, you can try out the new demo for the Bronze Age RTS game TFC: The Fertile Crescent on Steam. This is the Steam version of the popular free game available on, with the Steam version planned to have many enhancements over the original.

    TFC is a classic base-building RTS inspired by the struggles of growth, advancement, and conquest in the cradle of civilization. Establish your village near fertile lands, and balance your food surplus against the size of your civilian and military might, as you build your village. Think of it kind-of like a pixel-art Age of Empires but with some unique mechanics.

  • Fly Dangerous is an open source love-letter to the Elite Dangerous racing community | GamingOnLinux

    Racing is apparently a thing people do in Elite Dangerous and so one developer has decided to make a game as a love-letter to the community called Fly Dangerous.

    The developer mentions that racing in Elite is not particularly accessible, so the idea with Fly Dangerous is to provide a "ground-up reimplementation of a similar-enough flight model to provide a training ground and common set of tools to track leaderboards, ghosts and general tom-foolery". Sounds like it could be fun and just recently Alpha 6 was released adding in a new ship, customization for ships, a new biome map and the start of upgrades for the Time Trial mode to have some actual maps and progression.

  • Children of Morta: Ancient Spirits gives you a new character with two different forms | GamingOnLinux

    Children of Morta: Ancient Spirits is the brand new expansion that's out now from Dead Mage and 11 bit studios, sounds like it's pretty great too. I still can't get over how good the art is.

    Introducing Yajouj’Majouj, a new playable character only available in the Family Trials mode. This character has two different forms allowing you to quickly switch between, allowing you to combine different attack types together.

  • More Fallout New Vegas bugs on Wine with Lutris. The New Vegas Anti Crash mod fixes things, and is also compatible with Fallout 3 and The Elder Scrolls IV: Oblivion. – BaronHK's Rants

    So, my character on Fallout New Vegas got further into the wasteland and the game started freezing and stuttering every 10-20 minutes of gameplay.


    However, as with most Bethesda titles, Fallout New Vegas was infamous over the years for crashing to the desktop on Windows, and not even in a way where you could pin it down entirely and say “Oh well, that’s where it started!”, because Windows itself changes internally.

    It’s really funny, because anti-GNU/Linux trolls say that GNU/Linux changes underneath and maybe some compiled code doesn’t behave as you might expect years down the road, and that Windows is so great.

    The truth is that unless an OS was to stop being developed entirely, including security patches, there would be no way to ever fully guarantee 100% compatibility forever.

  • GT210 Nvidia card for old workhorse PC

    Ah, the beautiful month of October, probably my favorite month of the year. The temperature outside is just right; not too hot, not too cold. The tourist season is over. The month when most of my family members were married.

    What’s even better with this particular October of 2021, however, is that it’s been quite the month as far as game releases. Just this week we had Nickelodeon All-Star Brawl (review on that coming real soon), Far Cry 6 for FPS fans, and today marks the release of Metroid Dread. The curious part of me, of course, wanted to test to see how well Metroid Dread would run with Ryujinx, my preferred Switch emulator for Linux.

  • Fun, Franchises and ReMastered Classic Games

    This of course brings me to the last two weeks in which I purchased two aRPGs (Action RPGs). One was a remastered version of an absolute classic, Diablo 2: Resurrected. It's basically the same game as 20 years ago with a total visual overhaul. Every other aspect of the game has been left untouched. The second is a much newer game that came out in the last couple years for the Switch and recently made it's way to Steam and runs on Linux via Proton: Minecraft: Dungeons.

  • Valve opens up a Steam Deck to explain why it thinks you shouldn’t

    Valve has posted an official teardown of its upcoming handheld gaming PC, the Steam Deck. Before diving into the teardown, though, the company spends about a minute to strongly caution against taking one apart unless you’re sure you know what you’re doing.

  • Valve tears down Steam Deck (but don’t you dare do this at home)

    Indeed, the 5-minute video goes into great detail on how to perform Steam Deck surgery, and even states you have the “right” to open up your Steam Deck, but more than half of the video discourages you from doing so.

    Want to see inside a Steam Deck? Valve has delivered in the latest video although they're keen to remind people not to do any of this yourself.

    Valve say it's both a "How to" video and a "Why you shouldn't do any of this". Although they mention once you have it you have a right to do so, it's not recommended. With everything packed so tightly together they're giving a warning about damage to batteries, something that could cause a fire so there's a threat to your life kind of warning involved if you do it wrong. The warranty also doesn't cover any damage done by you if you really choose to do this.

  • Steam Deck: How to disassemble Valve's handheld gaming PC (and why you shouldn't) - Liliputing

    Valve’s Steam Deck is a handheld gaming PC with a 7 inch display, built-in game controllers, a custom AMD processor with RDNA 2 graphics, and a starting price of $399, which makes the Steam Deck one of the most affordable devices in its category.

    But the entry-level model has just 64GB of eMMC storage, which means you have to pay $529 or more to get a version with a faster, higher-capacity PCIe NVMe solid state drive. The good news is a new video from Valve shows exactly how to open up the Steam Deck and add or upgrade an SSD. The bad news is Valve highly recommends you don’t actually do that, since there’s a high risk that you’ll damage your device.

  • Wine (still) needs 32-bit MP3 plug-in from Gstreamer that the package doesn’t depend on in order to play MP3 in certain Bethesda video games. Gaming on Debian 11 GNU/Linux. – BaronHK's Rants

    A long time ago in Fedora, I ran into a bug in Wine’s packaging and it seems the bug is still a problem today in WineHQ’s official packages for Debian.

    I reported this issue to them in the Bugzilla a long time ago, and they told me to report it to Fedora, I reported it to Fedora, Fedora closed it for inactivity, and then it turns out WineHQ has the same packaging problem themselves. Sadly, even when the fix is trivial, I’ve gotten used to being ignored because the developers don’t have it happening to them or something.

    Some Bethesda video games running in Wine use MP3 for their in-game music, and Fallout New Vegas and The Elder Scrolls: Oblivion certainly do.

  • What you need to know about Kubernetes NetworkPolicy |

    With a growing number of cloud-native applications going to production through Kubernetes adoption, security is an important checkpoint that you must consider early in the process. When designing a cloud-native application, it is very important to embed a security strategy up front. Failure to do so leads to lingering security issues that can cause project delays and ultimately cost you unnecessary stress and money. For years, people left security at the end—until their deployment was about to go into production. That practice causes delays on deliverables because each organization has security standards to adhere to, which are either bypassed or not followed with a lot of accepted risks to make the deliverables. Understanding Kubernetes NetworkPolicy can be daunting for people just starting to learn the ins and outs of Kubernetes implementation. But this is one of the fundamental requirements that you must learn before deploying an application to your Kubernetes cluster. When learning Kubernetes and cloud-native application patterns, make your slogan "Don't leave security behind!"

  • 3 tips for printing with Linux

    I have a confession to make. This may be an unpopular opinion. I actually enjoy reading documents on a piece of paper as opposed to digitally. When I want to try a new recipe, I print it out to follow it so I don't have to continually swipe my mobile device to keep up with the steps. I store all my favorite recipes in sheet protectors in a binder. I also like to print out coloring pages or activity sheets for my kids. There are a ton of options online or we create our own! Though I have a fond appreciation for printed documents, I have also had my fair share of printing nightmares. Paper jams, low ink, printer not found, the list of frustrating errors goes on and on. Thankfully, it is possible to print frustration-free on Linux. Below are three tutorials you need to get started printing on Linux. The first article walks through how to connect your printer to your Linux computer. Then, learn how to print from anywhere in your house using your home network.

  • Strange Apache Reload Issue « etbe - Russell Coker

    I recently had to renew the SSL certificate for my web server, nothing exciting about that but Certbot created a new directory for the key because I had removed some domains (moved to a different web server). This normally isn’t a big deal, change the Apache configuration to the new file names and run the “reload” command. My monitoring system initially said that the SSL certificate wasn’t going to expire in the near future so it looked fine. Then an hour later my monitoring system told me that the certificate was about to expire, apparently the old certificate came back! I viewed my site with my web browser and the new certificate was being used, it seemed strange. Then I did more tests with gnutls-cli which revealed that exactly half the connections got the new certificate and half got the old one. Because my web server isn’t doing anything particularly demanding the mpm_event configuration only starts 2 servers, and even that may be excessive for what it does. So it seems that the Apache reload command had reloaded the configuration on one mpm_event server but not the other!

    It was only last month that M5Stack launched the M5Stamp Pico module based on an ESP32-PICO-D4 SiP and heat-resistant plastic shell, but M5Stamp C3 board is already out with most of the same specifications and features but an ESP32-C3 RISC-V SoC replaces the ESP32 dual-core Xtensa processor. M5Stamp C3 offers WiFi 4 and Bluetooth 5.0 with high bitrate and long-range connectivity and comes with the same heat-resistant plastic shell, but the company also highlights the RSA-3072-based secure boot and the AES-128-XTS-based flash encryption as a more secure way to address Bluetooth security concerns.

  • Alibaba open sources four RISC-V cores: XuanTie E902, E906, C906 and C910 - CNX Software

    Alibaba introduces a range of RISC-V processors in the last few years with the Xuantie family ranging from the E902 micro-controller class core to the C910 core for servers in data centers. This also includes the XuanTie C906 core found in the Allwinner D1 single-core RISC-V processor. While RISC-V is an open standard and there’s a fair share of open-source RISC-V cores available, many commercial RISC-V cores are closed source, but Zhang Jianfeng, President of Alibaba Cloud Intelligence speaking at the 2021 Apsara Conference, announced that T-Head had open-sourced four RISC-V-based Xuantie series processor cores, namely Xuantie E902, E906, C906, and C910, as well as related software and tools.

  • SiFive Has A New RISC-V Core To Improve Performance By 50%, Outperform Cortex-A78 - Phoronix

    SiFive just shared word that at today's Linley Conference they teased their Performance P550 successor that will "set a new standard for the highest efficiency RISC-V processor available."

  • This tinyML device counts your squats while you focus on your form | Arduino Blog

    Getting in your daily exercise is vital to living a healthy life and having proper form when squatting can go a long way towards achieving that goal without causing joint pain from doing them incorrectly. The Squats Counter is a device worn around the thigh that utilizes machine learning and TensorFlow Lite to automatically track the user’s form and count how many squats have been performed. Creator Manas Pange started his project by flashing the tf4micro-moition-kit code to a Nano 33 BLE Sense, which features an onboard three-axis accelerometer. From there, he opened the Tiny Motion Trainer Experiment by Google that connects to the Arduino over Bluetooth and captures many successive samples of motion. After gathering enough proper and improper form samples, Manas trained, tested, and deployed the resulting model to the board.
