Ubisoft's Launcher Broke Its Own Games on Linux and Steam Deck

Earlier this week NME reported: With an update to Ubisoft Connect, Ubisoft has broken Steam Deck and Linux compatibility for a number of its biggest games including The Division 2 and Assassin's Creed Valhalla. As reported by GamingOnLinux, the compatibility issues were caused by Ubisoft issuing an update for its Ubisoft Connect launcher. Even if Ubisoft's titles are bought through Steam, they still launch with Ubisoft Connect and require a connection with the third-party launcher to run. "Thankfully, Steam Deck users have already figured out that updating the device's Proton Experimental version and switching all Ubisoft games to use it resolves the issue," added GameRant. But Gaming on Linux described the incident as third-party launchers on Steam "once again being a massive nuisance." Why do developers and publishers keep forcing these absolutely useless third-party launchers on us? Never once have I, or anyone I've spoken to, actually wanted them. They only ever cause problems and solve basically nothing that Steam cannot already do directly. And PC Gamer agrees: This is yet another example of frustrating third-party launchers only making everyone's lives more difficult. I don't even want to know Ubisoft Connect exists, let alone have it flash up in my face and not be able to play my games because it's not working properly. I understand these companies want my data but you're supposed to be sneakier and better at getting it than this by now.

Proposed Linux Patch Allows Disabling CPU Security Mitigations at Build-Time

著者: EditorDavid
2023年2月5日 00:34
Phoronix reports: A proposed Linux kernel patch would provide a new Kconfig build time option of "CONFIG_DEFAULT_CPU_MITIGATIONS_OFF" to build an insecure kernel if wanting to avoid the growing list of CPU security mitigations within the kernel and their associated performance overhead. While risking system security, booting the Linux kernel with the "mitigations=off" option has been popular for avoiding the performance costs of Spectre, Meltdown, and the many other CPU security vulnerabilities that have come to light in recent years. Using mitigations=off allows run-time disabling of the various in-kernel security mitigations for these CPU problems. A patch proposed this week would provide CONFIG_DEFAULT_CPU_MITIGATIONS_OFF as a Kconfig switch that could optionally be enabled to have the same affect as mitigations=off but to be applied at build-time to avoid having to worry about setting the "mitigations=off" flag.

Mabox Linux Called 'Throwback to Old-School Linux'

著者: EditorDavid
2023年1月15日 02:34
"If you've been itching to try an Arch Linux distribution and want something outside of the usual GNOME/KDE/Xfce desktop environments, Mabox Linux is an outstanding option...." writes ZDNet's Jack Wallen. "It reminded me of my early days using Linux, only with a bit of a modern, user-centric twist...." Linux was hard in its infancy. So, when I see a Linux distribution that reminds me of those days but manages to make it easy on users without years of experience under their belts, it reminds me how far the open-source operating system has come. Such is the case with Mabox Linux.... It's not that Mabox doesn't make Arch Linux easy...it does. But when you first log into the desktop, you are greeted with something most hard-core Linux users love to see but can be a real put-off to new users. I'm talking about information...and lots of it. You see, Mabox Linux places four information-centric widgets front and center on the desktop, so you can get an at-a-glance look at how the OS is using your system resources and even two widgets that give you keyboard shortcuts for things like opening various apps, menus, and even window management controls. Also on the OpenBox Window Manager desktop, you'll find a single top panel that gives you quick access to all your installed apps, the Mabox Colorizer... and a system tray with plenty of controls.... Once you have the distribution installed, the big surprise comes by way of performance. Mabox Linux is amazingly fast...like faster than most distributions I've used. A big part of that is due to the OpenBox Window Manager, which is very lightweight. Compared to my regular GNOME-based Linux desktop, Mabox is like driving a Lamborgini instead of a Prius. The difference is that obvious. The installation process lets you choose between open-source or proprietary video drivers, the article points out. And "you can easily customize the color of your Mabox desktop, including the theme, side panels, Conky (which creates the desktop widgets), wallpaper, Tint2 Panel, and even the terminal theme."

Vanilla OS Offers a New Take on Security for the Linux Desktop

著者: EditorDavid
2023年1月8日 02:34
OS News cheers the first official release of Vanilla OS, calling it "an immutable desktop Linux distribution that brings some interesting new technologies to the table, such as the Apx package manager." From the official release announcement: "By default, Apx provides a container based on your Linux distribution (Ubuntu 22.10 for Vanilla OS 22.10) and wraps all commands from the distribution's package manager (apt for Ubuntu). Nevertheless, you can install packages from other package distributions.... Using the --dnf flag with apx will create a new container based on Fedora Linux. Here, apx will manage packages from Fedora's DNF repository, tightly integrating them with the host system. ZDNet calls Vanilla OS "a new take on Linux that is equal parts heightened security and user-friendly." Among other things, "the developers opted to switch to ABRoot, which allows for fully atomic transactions between 2 root partitions." The official release announcement explains: ABRoot will check which partition is the present root partition (i.e A), then it will mount an overlay on top of it and perform the transaction. If the transaction succeeds, the overlay will be merged with the future root partition (i.e B). On your next boot, the system will automatically switch to the new root partition (B). In case of failure, the overlay will be discarded and the system will boot normally, without any changes to either partition. But ZDNet explains why this comes in handy: Another really fascinating feature is called Smart Updates, which is enabled in the Vanilla OS Control Center, and ensures the system will not update if it's either under a heavy load or the battery is low. To enable this, open the Vanilla OS Control Center, click on the Updates tab, and then click the ON/OFF slider for SmartUpdate. Once enabled, updates will go through ABRoot transitions and aren't applied until the next reboot. Not only does this allow the updates to happen fully in the background, but it also makes them atomic, so they only proceed when it's guaranteed they will succeed. The only caveat to this system is that you are limited to either weekly or monthly updates, as there is no daily option for scheduling. However, if you're doing weekly updates, you should be good to go.... Setting aside that which makes Vanilla OS special, the distribution is as stock a GNOME experience as you'll find and does a great job serving as your desktop operating system. It's easy to use, reliable, and performs really well...especially considering this is the first official release. "Every wallpaper has a light and a dark version," adds the release announcement, "so you can choose the one that best suits your needs."

The Linux Kernel Has Been Forcing Different Behavior For Processes Starting With 'X'

著者: BeauHD
2022年11月9日 08:20
"An ugly hack within the Linux kernel that has been in mainline for over three years has been called out," writes Phoronix's Michael Larabel. "Due to a buggy X.Org Server / xf86-video-modesetting DDX, the Linux kernel has been imposing different behavior on whether a process starts with 'X' and in turn disable the atomic mode-setting support." Linux security researcher and WireGuard creator, Jason Donenfeld, discovered the 'ugly code' within the kernel and commented on it via the kernel mailing list. "The commit to this kernel with the 'X' first character check was made back in September 2019," notes Larabel. "The 'good' news is that since then on user-space side back in 2019 the xf86-video-modesetting code went ahead and disabled atomic support by default. So technically if running an updated X.Org stack within the past three years, this kernel hack isn't necessary anymore since user-space is just then avoiding the atomic API."

'Old/Weird Laptops' Sought To Help Test Linux Kernel Backlight Drivers

著者: msmash
2022年10月28日 04:22
Do you have a laptop that's either "pretty old" or "weird in some other way"? Did it ship without Windows from the factory, or did you flash its firmware with coreboot? You could help the Linux kernel move its backlight code forward without abandoning quirky gear like yours. ArsTechnica: Hans de Goede, a longtime Linux developer and principal engineer at Red Hat, writes on his Livejournal about the need to test "a special group of laptops" to prevent their backlight controls from disappearing in Linux kernel 6.1. Old laptop tests are needed because de Goede is initiating some major changes to user-space backlight controls, something he has been working on since 2014. As detailed at Linux blog Phoronix, there are multiple issues with how Linux tries to address the wide variety of backlight schemes in displays, which de Goede laid out at the recent Linux Plumbers Conference. There can be multiple backlight devices operating a single display, leaving high-level controls to "guess which one will work." Brightness control requires root permissions at the moment. And "0" passed along as a backlight value remains a conundrum, as the engineer pointed out in 2014: Is that entirely off, or as low as the display can be lit?

Linus Torvalds To Kernel Devs: Grow Up and Stop Pulling All-Nighters Just Before Deadline

著者: BeauHD
2022年10月18日 11:02
Linux kernel boss Linus Torvalds has released the first release candidate for version 6.1 of the project and added an appeal for developers to make his life easier by adding code earlier in the development cycle. The Register reports: "Let me just say that after I got my machine sorted out and caught up with the merge window, I was somewhat frustrated with various late pull requests. I've mentioned this before, but it's _really_ quite annoying to get quite a few pull requests in the last few days of the merge window." He then offered further guidance on how kernel devs can do it right. "Yes, the merge window is two weeks, but that's very much to allow me time to look things over, not 'two weeks to hurriedly put together a branch that you send Linus on Friday of the second week'," he wrote. "The whole 'do an all-nighter to get the paper in the day before the deadline' is something that should have gone out the window after high school. Not for kernel development." His next line was: "You know who you are." "Anyway, it's not the first time I've said this, I doubt it will be the last. But maybe more people could take it to heart, ok?" he added, before concluding his post with a slightly non-traditional call for testers to visit Linux's git tree because "The merge window may not be the biggest ever, but it's certainly big enough that the shortlog is much too big to post, and below is just my usual merge log." "For all the gory details, please refer to the git tree."

Bad DIMM on Linus Torvalds' Desktop System Moves Kernel Merges to His Laptop

著者: EditorDavid
2022年10月16日 20:34
When a kernel developer asked Linus Torvalds if he'd missed a Git pull, Torvalds "revealed the request was still in his queue as 'I'm doing merges (very slowly) on my laptop, while waiting for new ECC memory DIMMs to arrive,'" reports The Register: Torvalds needs the DIMMs because over the last few days he experienced what he described as "some instability on my main desktop... with random memory corruption in user space resulting in my allmodconfig builds randomly failing with internal compiler errors etc." The Linux boss's first thought was that a new kernel bug had caused the problem — which isn't good but sometimes happens. His instinct was wrong. "It was literally a DIMM going bad in my machine randomly after 2.5 years of it being perfectly stable," he wrote. "Go figure. Verified first by booting an old kernel, and then with memtest86+ overnight." Torvalds appears to have been tracking delivery of the new DIMMs as he reported replacement memory was "out for delivery" and predicted it should arrive later on Sunday evening.... His post also mentions that his main PC was set up for error correction code memory (ECC memory), but "during the early days of COVID when there wasn't any ECC memory available at any sane prices. And then I never got around to fixing it, until I had to detect errors the hard way." "I absolutely *detest* the crazy industry politics and bad vendors that have made ECC memory so 'special'," he added.

Linus Torvalds: Rust Will Go Into Linux 6.1

2022年9月20日 07:40
slack_justyb writes: As previously indicated on Slashdot, Rust was slated to be coming to the Linux Kernel sometime in the 6.x version. Well wonder no longer on which version of kernel 6.x will have the first bits of Rust officially in the kernel, as Linus has confirmed that 6.1 will be the first with the new NVMe kernel drivers being in Rust. The first version non-production ready code for the NVMe Rust based kernel drivers were already producing performance comparable to C code. So the final drivers to hit 6.1 are already looking promising. It also helped Rust's case that, thanks to the ground-breaking work of Linux kernel and Rust developer Miguel Ojeda, Rust on Linux has gotten much more mature. Kernel maintainers were convinced it is time to move forward with Rust in Linux. In short, they agreed that Rust on Linux was ready for work.

Ubuntu Upgrades Now Arrive with a Simple Prompt (and Security Fixes)

著者: EditorDavid
2022年8月21日 00:34
"After a slight delay due to an installer issue, the first point release for Ubuntu 22.04 has been officially released," swrites Jack Wallen for TechRepublic. "Although point releases are often overlooked by users, because they aren't major upgrades, this time around you should certainly run the upgrade immediately." The biggest reason is that this point release combines all of the security fixes and improvements that have been added since the initial release of Jammy Jellyfish. So, if you haven't bothered to upgrade Ubuntu 22.04 since you first installed it, which you should have been doing all along, this point upgrade will add everything you've missed in one fell swoop. One of the biggest upgrades for end users will be the ability of 20.04 users to upgrade to the latest release without having to touch the command line. At some point, users of 20.04 will see an upgrade prompt on their desktops, allowing them to easily make the jump to 22.04.1. This is a big deal because previously such upgrades would have required running several commands. That means no more: sudo apt-get update sudo apt-get upgrade -y sudo apt-get dist-upgrade -y sudo do-release-upgrade -y Another point release found in 22.04.1 is GNOME 42, which features a new enhanced dark mode and switches to Wayland by default, with the inclusion of Xorg for unsupported hardware.

Linux May Soon Lose Support For the DECnet Protocol

著者: BeauHD
2022年8月4日 09:45
Microsoft software engineer Stephen Hemminger has proposed removing the DECnet protocol handling code from the Linux kernel. The Register reports: The timing is ironic, as this comes just two weeks after VMS Software Inc announced that OpenVMS 9.2 was really ready this time... That announcement, of course, came some months after the first time it announced [PDF] version 9.2 [...]. The last maintainer of the DECnet code was Red Hat's Christine Caulfield, who flagged the code as orphaned in 2010. The change is unlikely to vastly inconvenience many people: VMS is the last even slightly mainstream OS that used DECnet, and VMS has supported TCP/IP for a long time. Indeed, for decades, the oldest email in this reporter's "sent" folder was a 1993 enquiry about the freeware CMUIP stack for VMS. One of the easier ways to bootstrap VMS on an elderly VAX these days is to install it on the SimH VAX hardware simulator, and then net-boot the real VAX from the simulated one. Anyone keen enough to do that will be competent to run an older version of Linux just for the purpose. Although their existence is rapidly being forgotten today, TCP/IP is not the only network protocol around, and as late as the mid-1990s it wasn't even the dominant one. The Linux kernel used to support multiple network protocols, but they are disappearing fast. [...] For a long time, DECnet was a significant network protocol. DEC supplied a client stack called PathWorks to let DOS, Windows and Mac clients connect to VAX servers, not only for file and print, but also terminal connections and X.11. Whole worldwide WANs ran over DECnet, and as a teenage student, your correspondent enjoyed exploring them.

What's New in Linux Mint 21 Cinnamon

著者: EditorDavid
2022年8月1日 04:24
Today saw the release of Linux Mint 21 "Vanessa" Cinnamon Edition, a long term support release (supported until 2027). Release notes at LinuxMint.com promise that it comes with "refinements and many new features to make your desktop experience more comfortable." Among the highlights: its Bluetooth manager is now Blueman (instead of Blueberry). Blueberry depended on gnome-bluetooth, which was developed exclusively for GNOME. In contrast, Blueman relies on the standard Bluez stack which works everywhere and can even be used or queried from the command line. The Blueman manager and tray icon provide many features that weren't available in Blueberry and a lot more information which can be used to monitor your connection or troubleshoot Bluetooth issues. Out of the box Blueman features better connectivity, especially when it comes to headsets and audio profiles. In preparation for Linux Mint 21 the Blueman user interface was improved and received support for symbolic icons. Upstream, Blueman and Bluez are actively developed and used in many environments. The lack of thumbnails for some common file types was identified as a usability issue. To address it a new Xapp project called xapp-thumbnailers was started and is now featured in Linux Mint 21. The project brings support for the following mimetypes: - AppImage - ePub - MP3 (album cover) - RAW pictures (most formats) - Webp Automated tasks are great to keep your computer safe but they can sometimes affect the system's performance while you're working on it. A little process monitor was added to Linux Mint to detect automated updates and automated system snapshots running in the background. Whenever an automated task is running the monitor places an icon in your system tray. Your computer might still become slow momentarily during an update or a snapshot, but with a quick look on the tray you'll immediately know what's going on.... Linux Mint 21 uses IPP, also known as Driverless Printing and Scanning (i.e. a standard protocol which communicates with printers/scanners without using drivers). For most printers and scanners no drivers are needed, and the device is detected automatically. And there's also a fabulous collection of new backgrounds.

Fedora Sours On Creative Commons 'No Rights Reserved' License

waspleg writes: Fedora, the popular Linux distribution, will no longer incorporate software licensed under CC0, the Creative Commons "No Rights Reserved" license. In order to support the wide re-use of copyrighted content in new works, CC0 provides authors "a way to waive all their copyright and related rights in their works to the fullest extent allowed by law." The license arose in response to the 1998 Sonny Bono Copyright Term Extension Act (CTEA), which extended the duration of copyright by 20 years at the expense of the public domain. But CC0 explicitly says the licensor does not waive patent rights, which for free and open source software (FOSS) is a potential problem. That means, for instance as described here, if you use CC0-licensed code in your project, and the author of that code later claims your project is infringing a patent they own regarding that code, your defense will be limited. Avoiding the use of CC0-licensed code is one way to steer clear of these so-called submarine patents that could years later torpedo you. In a message to The Fedora Project's mailing list for legal issues, Richard Fontana, a technology lawyer for Red Hat (which sponsors Fedora), explained that while CC0 is cited as a "good license," it won't be for much longer. "We plan to classify CC0 as allowed-content only, so that CC0 would no longer be allowed for code," said Fontana. "This is a fairly unusual change and may have an impact on a nontrivial number of Fedora packages (that is not clear to me right now), and we may grant a carveout for existing packages that include CC0-covered code." Fontana said there's a growing consensus in the FOSS community that licenses without any form of patent licensing or forbearance aren't suitable. CC0, he said, like other Creative Commons licenses, includes a clause that explicitly states no patent rights are waived by the licensor.

Six Ground-Breaking New Linux Laptops Released in the Last Two Weeks

著者: EditorDavid
2022年7月11日 05:21
In the last two weeks, six new Linux laptops have hit the market (or were announced). "The Linux hardware scene is getting better by the day," writes the site FOSS Weekly: Star Labs teases its new StarFighter Linux Laptop with a 4K (10-bit IPS) display. MNT Research introduces a "more affordable" 7-inch mini Linux laptop, the MNT Pocket Reform. KDE's Slimbook 4 is here with AMD Ryzen 7 5700U processor and a better battery, starting from $1,000. "Buying from Slimbook supports KDE development too," notes Gaming on Linux, adding that there's a choice of 14 or 15.6 inch displays. TUXEDO's Pulse 15 — Gen2 (also with an AMD Ryzen 7 5700U processor) has a 15-inch HiDPI WQHD 165Hz display, along with eight cores and 16 threads. (And the Register notes its twin cooling fans, "allowing them to overclock the chip and run it at 35W," and a choice of distros.) Pre-orders have opened for the Roma — the first RISC-V Laptop (which may ship in September). Ars Technica reports they're offering "free Silicon upgrades" — that is free system-on-a-chip and system-on-module upgrades for its quad-core RISC-V CPU. And there's also a companion NPU/GPU, notes a blog post at RISCV.org, "for the fastest, seamless RISC-V native software development available." (As well as "early access to next-generation laptop and accessory upgrades at generous discounts or for free.") The blog post calls it a "Web3-friendly platform with NFT creation and publication plus integrated MetaMask-style wallet." System 76's "Lemur" Alder Lake- and coreboot-powered laptop arrives with 14 hours of battery life.

Alder Lake-Powered Linux Laptop Arrives With 14 Hours of Battery Life

著者: BeauHD
2022年7月8日 19:00
System76, the Colorado-based Linux laptop, desktop, and server specialist, has announced a new highly portable laptop with an Intel Alder Lake processor inside. Tom's Hardware reports: The new Lemur Pro(opens in new tab) is a "lighter than Air" 14-inch form factor laptop with excellent battery life and attractions such as open firmware (powered by Coreboot) and a 180-degree hinge. In addition, buyers can choose to go with Pop!_OS 22.04 LTS or Ubuntu 22.04 LTS pre-installed. The new Lemur Pro has many attractive modern features you might see advertised in many rival mainstream thin and light designs. However, the special sauce here is the "System76 Open Firmware with Coreboot." Coreboot, known initially as LinuxBIOS, is significant as it is an open-source BIOS implementation embraced by Linux users. It is lightweight, flexible, and feature-rich. [...] System76 has designed the Lemur Pro with monitor-based docking in mind. It envisions users connecting to a big screen using the USB-C connection to benefit from the more expansive workspace and laptop charging. Like Windows, Linux had to have some serious tinkering under the hood to prepare for the mix of Performance and Efficiency cores in Alder Lake chips. However, rest assured, efficient hybrid scheduling is taken care of with the two OS options that can be pre-installed on the Lemur Pro. System76 allows customers to configure and buy Lemur Pro laptops right now. There are many RAM and storage configurations to pick through, and you can add external keyboards and monitors to the bundle. The entry price with an Intel Core i5-1235U, 8GB RAM, 240GB of storage, and no extras is $1,149. However, the Core i7-1255U model is a bit of a stretch, adding $200 to the base price for the faster CPU clocks.

Linus Torvalds Says Rust For The Kernel Could Possibly Be Merged For Linux 5.20

著者: msmash
2022年6月23日 23:00
Speaking this week at the Linux Foundation's Open-Source Summit, Linus Torvalds talked up the possibilities of Rust within the Linux kernel and that it could be landing quite soon -- possibly even for the next kernel cycle. From a report: Linus Torvalds and Dirk Hohndel had their usual Open-Source Summit keynote/chat where Linus commented on Rust programming language code within the kernel. Torvalds commented that real soon they expect to have the Rust infrastructure merged within the kernel, possibly even for the next release -- meaning Linux 5.20. There hasn't yet been any Rust for Linux pull request sent in or merged yet, but things have begun settling down in the initial Rust enablement code for the kernel with the basic infrastructure, a few basic sample drivers, etc. Last month saw the most recent Rust Linux kernel patches posted that got more functionality into shape and additional reviews completed. As noted plenty of times before, this Rust support within the Linux kernel will remain optional when building the kernel depending upon whether you want the support or any of the kernel features to be implemented just in Rust code.

Ubuntu Working To Provide Good Support For The VisionFive Low-Cost RISC-V Board

著者: EditorDavid
2022年6月13日 01:34
"Ubuntu developers have been working on bringing up and improving support for the Starfive VisionFive," writes Phoronix, calling the $179 device "one of the most promising 'low-cost' RISC-V single board computers to date... intended to run full-blown RISC-V Linux distributions." The board comes in two varieties with 4GB or 8GB of system memory, powered by a dual-core SiFive U74 RV64 SoC @ 1.0GHz, an NVDLA deep learning accelerator engine, a Tensilica-VP6 Vision DSP, and a neural network engine.... Considering the performance of the much more capable HiFive Unmatched development board (that is also multiple times more expensive) and even that sometimes being outpaced by the Raspberry Pi, don't get too excited for the dual-core 1.0GHz RISC-V 64-bit SoC for general purpose workloads. But this VisionFive board may be interesting for some machine learning and other use-cases thanks to its additional accelerators. It's also one of the few RISC-V boards capable of running a full Linux distribution in the sub-$200 space. Since the upstream Linux 5.17 kernel there has been mainline support for the VisionFive v1 board. Ubuntu developers are working on enabling the StarFive VisionFive board for their RISC-V kernel build.
