An anonymous reader writes: Five years after their original goal to ship Ubuntu with Wayland, Ubuntu 17.10 transitioned to using the Wayland display system by default as part of their transition to GNOME Shell as the default desktop. But with the upcoming Ubuntu 18.04 LTS release, Canonical has decided to transition back to the X.Org Server. Their reasoning for moving to an X.Org Server by default is better support for screen sharing, remote desktop, and better recovery from crashes. But for those interested the Wayland session will still be available as a log-in option.

An anonymous reader writes: Canonical has temporarily pulled the download links for Ubuntu 17.10 "Artful Aardvark" from the Ubuntu website due to ongoing reports of some laptops finding their BIOS corrupted after installing this latest Ubuntu release. The issue is appearing most frequently with Lenovo laptops but there are also reports of issues with other laptop vendors as well. This issue appears to stem from the Intel SPI driver in the 17.10's Linux 4.13 kernel corrupting the BIOS for a select number of laptop motherboards. Canonical is aware of this issue and is planning to disable the Intel SPI drivers in their kernel builds. Canonical's hardware enablement team has already verified this works around the problem, but doesn't provide any benefit if your BIOS is already corrupted.

An anonymous reader writes: While many of you have likely heard of the "RADV" open-source Vulkan driver, it's been a community-written driver up to this point in the absence of AMD's official, cross-platform Vulkan driver being open-source. That's now changed with AMD now open-sourcing their official Vulkan driver. The code drop is imminent and they are encouraging the use of it for quick support of new AMD hardware, access to the Radeon GPU Profiler, easy integration of AMD Vulkan extensions, and enabling third-party extensions. For now at least it does provide better Vulkan performance than RADV but the RADV developers have indicated they plan to continue development of their Mesa-based Vulkan driver.

An anonymous reader writes: Recently completed Linux distro benchmarks by Phoronix show Intel's Clear Linux is the most powerful on x86 hardware. A six-way, enterprise-focused Linux distro comparison show Clear Linux being the fastest with a Core i9 and Xeon systems, easily beating CentOS, openSUSE, and Ubuntu in a majority of the tests.

When doing an 11-way Linux distro boot test they also found Clear Linux easily booted the fastest followed by the Clear-inspired Solus distribution. Clear Linux does work on AMD hardware and works on Intel CPUs back to Sandy Bridge but leverages its speed from optimized compiler settings, specially built libraries capable of AVX instructions on supported systems, a specially tuned kernel configuration, and other optimizations/patches.
Debian 9.2 and Fedora 27 "ended up being dropped from this article due to data overload," the article concludes, "and those distributions really not offering anything really different in terms of the performance."

Michael Larabel, writing for Phoronix: Intel is planning to end "legacy BIOS" support in their new platforms by 2020 in requiring UEFI Class 3 or higher. Making rounds this weekend is a slide deck from the recent UEFI Plugfest. Brian Richardson of Intel talked about the "last mile" barriers to removing legacy BIOS support from systems. By 2020, they will be supporting no less than UEFI Class 3, which means only UEFI support and no more legacy BIOS or CSM compatibility support mode. But that's not going to force on UEFI Secure Boot unconditionally: Secure Boot enabled is considered UEFI Class 3+. Intel hasn't removed legacy BIOS / CSM support yet due to many customers' software packages still relying upon legacy BIOS, among other reasons. Removing the legacy BIOS support will mitigate some security risks, needs less validation by vendors, allows for supporting more modern technologies, etc.

diegocg quotes Kernel Newbies: Linux 4.11 has been released. This release adds support for bigger memory limits in x86 hardware (128PiB of virtual address space, 4PiB of physical address space); support for AMD Secure Memory Encryption; a new unwinder that provides better kernel traces and a smaller kernel size; support for the zstd compression algorithm has been added to Btrfs and Squashfs; support for zero-copy of data from user memory to sockets; support for Heterogeneous Memory Management that will be needed in future GPUs; better cpufreq behaviour in some corner cases; faster TBL flushing by using the PCID instruction; asynchronous non-blocking buffered reads; and many new drivers and other improvements.
Phoronix has more on the changes in Linux 4.14 -- and notes that its codename is still "Fearless Coyote."

New submitter fstack writes: Senior software architect Mark Maybee who has been working at Oracle/Sun since '98 says maybe we "could" still see ZFS be a first-class upstream Linux file-system. He spoke at the annual OpenZFS Developer Summit about how Oracle's focus has shifted to the cloud and how they have reduced investment in Solaris. He admits that Linux rules the cloud. Among the Oracle engineer's hopes is that ZFS needs to become a "first class citizen in Linux," and to do so Oracle should port their ZFS code to Oracle Linux and then upstream the file-system to the Linux kernel, which would involve relicensing the ZFS code.

An anonymous reader writes: In a bid to help Android smartphone vendors the Linux LTS (Long Term Support) kernels will now be maintained for a period of six years. The Linux LTS initiative backed by the Linux Foundation has supported annual LTS kernels for two years worth of updates, but that is being changed for Linux 4.4+ at the request of Google and their Project Treble. This means the Linux 4.4 LTS kernel will be maintained through 2022 and the upcoming Linux 4.14 LTS through 2023 for security/bug fixes in order to last a complete "device lifecycle."

New submitter fstack writes: Phoronix has carried out tests comparing AMD's high-end EPYC 7601 CPU to AMD Opteron CPUs from about ten years ago, looking at the EPYC/Opteron Linux performance and power efficiency. Both on the raw performance and performance-per-Watt, the numbers are quite staggering though the single-threaded performance hasn't evolved quite as much. The EPYC 7601 is a $4,200 USD processor with 32 cores / 64 threads. The first of many tests was with NAS Parallel Benchmarks: "For a heavily threaded test like this, going from a single Opteron 2300 series to the EPYC 7601 yielded around a 40x increase in performance," reports Phoronix. "Not bad when also considering it was only a 16x increase in the thread count (4 physical cores to 32 cores / 64 threads). The EPYC 7601 has a lower base clock frequency than the Opteron 2300 CPUs tested but has a turbo/boost frequency higher, among many architectural advantages over these K10 Opterons. With the NASA test's Lower-Upper Gauss-Seidel solver, going from the dual Opteron 2384 processors to a single EPYC 7601 yields around a 25x improvement in performance over the past decade of AMD server CPUs. Or in looking at the performance-per-Watt with the LU.C test, it's also around a 25x improvement over these older Opterons."

Phoronix has been able to confirm that the new Ryzen CPUs are running stable without the segmentation fault problem that would occur under very heavy workloads. They have also been able to test now the Ryzen Threadripper 1950X. The Threadripper 1950X on Linux is unaffected by any issues unless you count the lack of a thermal reporting driver. With the 32 threads under Linux they have been able to build the Linux kernel in just about a half minute.

To celebrate Linux's 26th anniversary, the Linux Foundation tweeted a picture of Tux on a birthday cake, and linked to an essay on OpenSource.com by FreeDOS founder Jim Hall: My first Linux distribution was Softlanding Linux System (SLS) 1.03, with Linux kernel 0.99 alpha patch level 11. That required a whopping 2MB of RAM, or 4MB if you wanted to compile programs, and 8MB to run X windows... To celebrate, I reinstalled SLS 1.05 to remind myself what the Linux 1.0 kernel was like and to recognize how far Linux has come since the 1990s.
"Getting X windows to perform was not exactly easy..." Hall writes, adding "the concept of a desktop didn't exist yet." Meanwhile Phoronix celebrated by republishing that fateful email Linus Torvalds sent on August 25, 1991. And Fossbytes shared the most recent statistics about modern-day Linux's 20 million lines of code from the Linux Foundation: During the period between the 3.19 and 4.7 releases, the kernel community was merging changes at an average rate of 7.8 patches per hour; that is a slight increase from the 7.71 patches per hour seen in the previous version of this report, and a continuation of the longterm trend toward higher patch volumes.

An anonymous reader writes: Ryzen customers experiencing segmentation faults under Linux when firing off many compilation processes have now had their problem officially acknowledged by AMD. The company describes it as a "performance marginality problem" affecting some Ryzen customers and only on Linux. AMD confirmed Threadripper and Epyc processors are unaffected; they will be dealing with the issue on a customer-by-customer basis, and their future consumer products will see better Linux testing/validation. Ryzen customers believed to be affected by the problem can contact AMD Customer Care. Michael Larabel writes via Phoronix: "With the Ryzen segmentation faults on Linux they are found to occur with many, parallel compilation workloads in particular -- certainly not the workloads most Linux users will be firing off on a frequent basis unless intentionally running scripts like ryzen-test/kill-ryzen. As I've previously written, my Ryzen Linux boxes have been working out great except in cases of intentional torture testing with these heavy parallel compilation tasks. [AMD's] analysis has also found that these Ryzen segmentation faults aren't isolated to a particular motherboard vendor or the like, contrary to rumors/noise online due to the complexity of the problem."

An anonymous reader quotes Phoronix: Finalizing Fedora's switch from Python 2 to Python 3 by default is still going to take several more Fedora release cycles and should be done by the 2020 date when Python 2 will be killed off upstream. While much of Fedora's Python code is now compatible with Py3, the /usr/bin/python still points to Python 2, various python-* packages still mean Python 2... The end game is to eventually get rid of Python 2 from Fedora but that is even further out.
Fedora is now gathering feedback on a Wiki page explaining the switch.

sombragris writes: July 17 marked the 24th anniversary of Slackware Linux, the oldest GNU/Linux still in active development, being created in 1993 by Patrick Volkerding, who still serves as its BDFL. Version 14.2 was launched last year, and the development version (Slackware-current) currently offers kernel 4.9.38, gcc 7.1, glibc 2.25, mesa 17.1.5, and KDE and Xfce as official desktops, with many others available as 3rd party packages. Slackware is also among the Linux distributions which have not adopted systemd as its init system; instead, it uses a modified BSD init which is quite simple and effective. Slackware is known to be a solid, stable and fast setup, with easy defaults which is appreciated by many Linux users worldwide. Phoronix has a small writeup noting the anniversary and there's also a nice reddit thread.

After collating 30,171 responses, Phoronixhas released some results from their first Linux Laptop Survey. An anonymous reader quotes their report: To little surprise, Ubuntu was the most popular Linux distribution running on the respondents' laptops. 38.9% of the respondents were said to be using Ubuntu while interesting in second place was Arch Linux at 27.1% followed by Debian at 15.3%. Rounding out the top ten were then Fedora at 14.8%, Linux Mint in 5th at 10.8%, openSUSE/SUSE in sixth at 4.2%, Gentoo in seventh at 3.9%, CentOS/RHEL in eighth at 3.1%, Solus in ninth at 2%, and Manjaro in tenth at 1.6%. The other Linux distributions had each commanded less than 1% of the overall response.
Only 10.3% of respondents said their most recent laptop purchase came pre-loaded with Linux. But 29.3% are now dual-booting their Linux laptop with Windows, while another 4.4% were dual-booting with yet another Linux distribution.

Phoronix is hosting a 2017 Linux Laptop Survey. From their site: While Linux laptop compatibility is much better than where it was years ago, it's still not too uncommon to run into display/hybrid issues, shorter battery life under Linux than Windows or macOS, touchpad problems, and other occasional compatibility/performance shortcomings. So we've established this Linux Laptop Survey in conjunction with Linux stakeholders to hopefully gather more feedback that will be useful to many different parties...
The survey will be online until July 6th, after which the results will be publicly available, and will determine the most popular brands, distros, screen sizes, and GPUs, as well as common pain points and popular price points. And one particularly interestng question asks respondents what they'd like to see in a "dream Linux laptop."

An anonymous reader quotes Phoronix: UBports continues to be the leading community project for trying to let Ubuntu Touch live on and evolve under their direction... Among their recent achievements were acquiring more sponsors, all devices that were sold with Ubuntu Touch can now run with UBports' builds, they are working on their own version of Mozilla's AGPS Location Service to replace Canonical's GPS system, the Halium OS platform continues evolving, the Dekko email client is back under development, installation improvements are being worked on, they are still striving for Wayland support, and more.
The UBports Patreon page has even raised enough to allow UBports founder Marius Gripsgard to work full-time on what they're calling "a beautiful, free and open-source mobile OS." Their recent community update announced that "we are seeing more activity on Ubuntu Touch than for a very long time, and that is really encouraging."

"Debian project leader Mehdi Dogguy has written a status update concerning the work going on for the first two months of 2017," reports Phoronix. An anonymous reader quotes their report: So far this year Debian 9.0 Stretch has entered its freeze, bug squashing parties are getting underway for Stretch, the DebConf Committee is now an official team within Debian, a broad Debian Project roadmap is in the early stages of talk, and more.
Bug-Squashing Parties have been scheduled this week in Germany and Brazil, with at least two more happening in May in Paris and Zurich, and for current Debian contributors, "Debian is willing to reimburse up to $100 (or equivalent in your local currency) for your travel and accommodation expenses for participating in Bug Squashing Parties..." writes Dogguy, adding "If there are no Bug Squashing Parties next to your city, can you organize one?"

An anonymous reader quotes Phoronix: OPNsense 17.1 is now available as the newest release of this network-focused FreeBSD-based operating system forked from pfSense. It's now been two years since the first official release of OPNsense and to celebrate they have out a big update. OPNsense 17.1 re-bases to using FreeBSD 11.0, there's now a SSH remote installer, new language support, more hardening features used from HardenedBSD, new plugins, integrated authentication via PAM, and many other improvements. Some of the new plug-ins include FTP Proxy, Tinc VPN, and Let's Encrypt support.
This version has been named "Eclectic Eagle".

Libreboot became an official GNU project in May. Now an anonymous Slashdot reader writes: Richard Stallman has officially announced that Libreboot is no longer a GNU package. The maintainer of Libreboot had tried to leave the GNU project in September 2016, but the departure was not acknowledged until January 2017. Libreboot is a replacement for proprietary BIOS systems, effectively a distribution of coreboot without any binary blobs and adding an automated build/install process.
In the post titled "Goodbye to GNU Libreboot," Stallman wrote that "When a package's maintainer steps down, that doesn't by itself break the relationship between GNU and the package. If it is left without a maintainer but is still useful, the GNU Project will usually look for new maintainers to work on it. However, we can instead drop ties with the package, if that seems the right thing to do.

"A few months ago, the maintainer of GNU Libreboot decided not to work on Libreboot for the GNU Project any more. That was her decision to make. She also asserted that Libreboot was no longer a GNU package -- something she could not unilaterally do. The GNU Project had to decide what to do in regard to Libreboot. We have decided to go along with the former GNU maintainer's wishes in this case, for a combination of reasons: (1) it had not been a GNU package for very long, (2) she was the developer who had originally made it a GNU package, and (3) there were no major developers who wanted to continue developing Libreboot under GNU auspices."

Slashdot reader prisoninmate brings news from Softpedia: Today, Linus Torvalds proudly announced the release and availability for download of the Linux 4.8 kernel branch, which is now the latest stable and most advanced one. Linux kernel 4.8 has been in development for the past two months, during which it received no less than eight Release Candidate testing versions that early adopters were able to compile and install on their GNU/Linux operating system to test various hardware components or simply report bugs...

A lot of things have been fixed since last week's RC8 milestone, among which we can mention lots of updated drivers, in particular for GPU, networking, and Non-Volatile Dual In-line Memory Module (NVDIMM), a bunch of improvements to the ARM, MIPS, SPARC, and x86 hardware architectures, updates to the networking stack, as well as to a few filesystem, and some minor changes to cgroup and vm.
The kernel now supports the Raspberry Pi 3 SoC as well as the Microsoft Surface 3 touchscreen.

An anonymous Slashdot reader writes: I'm surprised this hasn't surfaced on Slashdot already, but yesterday Phoronix reported that systemd will soon be handling file system mounts, along with all the other stuff that systemd has encompassed. The report generated the usual systemd arguments over on Reddit.com/r/linux with Lennart Poettering, systemd developer and architect, chiming in with a few clarifications.
Lennart argued it will greatly improve the handling of removable media like USB sticks.

An anonymous reader writes: Fedora 25 will finally be the first release for this Linux distribution -- and the first tier-one desktop Linux OS at large -- that is going ahead and using Wayland by default. Wayland has been talked about for years as a replacement to the xorg-server and finally with the upcoming Fedora 25 release this is expected to become a reality. The X.Org Server will still be present on Fedora systems for those running into driver problems or other common issues.
Fedora's steering committee agreed to the change provided the release notes "are clear about how to switch back to X11 if needed." In addition, according to the Fedora Project's wiki, "The code will automatically fall back to Xorg in cases where Wayland is unavailable (like NVIDIA)."

"The first release candidate for the upcoming FreeBSD 11.0 is ready for testing," reports Distrowatch, noting various changes. ("A NULL pointer dereference in IPSEC has been fixed; support for SSH protocol 1 has been removed; OpenSSH DSA keys have been disabled by default...") Now an anonymous Slashdot reader writes: Sunday Phoronix performed some early benchmark testing, comparing FreeBSD 10.3 to FreeBSD 11.0 as well as DragonFlyBSD, Ubuntu, Intel Clear Linux and CentOS Linux 7. They reported mixed results -- some wins and some losses for FreeBSD -- using a clean install with the default package/settings on the x86_64/amd64 version for each operating system.

FreeBSD 11.0 showed the fastest compile times, and "With the SQLite benchmark, the BSDs came out ahead of Linux [and] trailed slightly behind DragonFlyBSD 4.6 with HAMMER. The 11.0-BETA4 performance does appear to regress slightly for SQLite compared to FreeBSD 10.3... With the BLAKE2 crypto test, all four Linux distributions were faster than DragonFlyBSD and FreeBSD... with the Apache web server benchmark, FreeBSD was able to outperform the Linux distributions..."

An anonymous Slashdot reader writes: The Linux 4.7 kernel made its official debut today with Linus Torvalds announcing, "after a slight delay due to my travels, I'm back, and 4.7 is out. Despite it being two weeks since rc7, the final patch wasn't all that big, and much of it is trivial one- and few-liners." Linux 4.7 ships with open-source AMD Polaris (RX 480) support, Intel Kabylake graphics improvements, new ARM platform/board support, Xbox One Elite Controller support, and a variety of other new features.
Slashdot reader prisoninmate quotes a report from Softpedia: The biggest new features of Linux kernel 4.7 are support for the recently announced Radeon RX 480 GPUs (Graphic Processing Units) from AMD, which, of course, has been implemented directly into the AMDGPU video driver, a brand-new security module, called LoadPin, that makes sure the modules loaded by the kernel all originate from the same file system, and support for generating virtual USB Device Controllers in USB/IP. Furthermore, Linux kernel 4.7 is the first one to ensure the production-ready status of the sync_file fencing mechanism used in the Android mobile operating system, allow Berkeley Packet Filter (BPF) programs to attach to tracepoints, as well as to introduce the long-anticipated "schedutil" frequency governor to the cpufreq dynamic frequency scaling subsystem, which promises to be faster and more accurate than existing ones.
Linus's announcement includes the shortlog, calling this release "fairly calm," though "There's a couple of network drivers that got a bit more loving."

"With Google Play and Android app support hitting Chromebooks, it's now possible to run Windows applications/games on Chromebooks via CrossOver For Android," reports Phoronix. Slashdot reader grungy writes: The first Intel ChromeBooks have access to the Play Store now, and the Android version of Wine apparently runs on them... Pictures show the Steam client running, and a clip of a D3D game. Of course, the Play Store is only available on the ChromeOS developer channel so far, but that should change later this year.
CrossOver for Android also hasn't been officially released, but Thursday CodeWeavers' president blogged excitedly that "we are staring at a Leprechaun riding on the back of a Unicorn while taking a picture of a UFO. We are running CrossOver through Android on a ChromeBook running a Windows based game launched from the Steam client. THIS HAS NEVER BEEN DONE BEFORE...EVER!!!"

An anonymous reader writes: Mesa3D developers have announced the release of Mesa 12.0. Mesa 12 notably adds open-source OpenGL 4.3 drivers for Intel, Radeon, and NVIDIA on Linux, and it also integrates the previously open-sourced Intel Vulkan graphics API driver. From the Phoronix analysis, "Mesa 12.0 is easily one of the biggest updates to this important open-source user-space OpenGL driver stack in quite some time and will offer much better support and features especially for Intel, Radeon, and NVIDIA open-source Linux desktop users/gamers." You can download Mesa 3D Graphics Library 12.0.0 here.

An anonymous reader writes: Michael Larabel at Phoronix has combined their new results from intensive Linux/Windows performance testing for popular games on Intel, AMD, and NVIDIA graphics cards, and at different resolutions. "This makes it easy to see the Linux vs. Windows performance overall or for games where the Linux ports are simply rubbish and performing like crap compared to the native Windows game." The games tested included Xonotic, Tomb Raider, Grid Autosport, Dota 2, Middle-earth: Shadow of Mordor, F1 2015, and Company of Heroes 2 -- and the results were surprising.

Xonotic v0.8 outperformed Windows with a NVIDIA card, but "The poor Xonotic performance on Linux with the Intel driver was one of the biggest surprises from yesterday's article. It's not anything we've seen with the other drivers." And while testing on the Source 2 engine revealed that Valve's Dota 2 "is a quality Linux port," most of the other results were disappointing -- regardless of the graphics card and driver. "Tomb Raider on Linux performs much worse than the Windows build regardless of your driver/graphics card... Shadow of Mordor's relative Linux performance is more decent than many other Linux games albeit still isn't running at the same speeds as the Windows games..."
The article concludes with a note of optimism. "Hopefully in due time with the next generation of games making use of Vulkan...we'll see better performance relative to Windows." Have Slashdot readers seen any performance issues while playing games on Linux?

Marius Nestor, reporting for Softpedia (condensed): Linux kernel 4.6.1 is already here, only two weeks after the official launch of the Linux 4.6 kernel series. For those not in the loop, Linux 4.6 branch is the latest and most advanced kernel branch available right now for GNU/Linux operating systems, but it looks like its adoption is a little slow at the moment. "I'm announcing the release of the 4.6.1 kernel. All users of the 4.6 kernel series must upgrade," says Greg Kroah-Hartman. "The updated 4.6.y git tree can be browsed at the normal kernel.org git web browser."
Some users are apparently facing boot failure issue on the latest version. An anonymous tipster tells Slashdot: Several folks on the web have reported a regression in the latest Linux kernels, starting with 4.6.1 and including the 4.7 beta that prevents booting and drops to busybox, at least the one supplied by the Ubuntu PPA. The boot sequence ends with "address family not supported by protocol: error getting socket" and then, "error initializing udev control socket" (screenshot here).

An anonymous coward writes: Just like clockwork, the Linux 4.6 kernel was officially released today. Details on the kernel changes for Linux 4.6 can be found via Phoronix and KernelNewbies.org. NVIDIA GeForce GTX 900 Maxwell support and Dell XPS 13 Skylake support are among the many hardware changes for 4.6. For Linux 4.7 there are already several new features to look forward to from new DRM display drivers to a new CPU scaling governor expected.
prisoninmate also writes: Linus Torvalds announced the final release of the anticipated Linux 4.6 kernel, which, after seven Release Candidate builds introduces features like "the OrangeFS distributed file system, support for the USB 3.1 SuperSpeed Plus (SSP) protocol, offering transfer speeds of up to 10Gbps, improvements to the reliability of the Out Of Memory task killer, as well as support for Intel Memory protection keys," [according to Softpedia].

"Moreover, Linux kernel 4.6 ships with Kernel Connection Multiplexor, a new component designed for accelerating application layer protocols, 802.1AE MAC-level encryption (MACsec) support, online inode checker for the OCFS2 file system, support for the BATMAN V protocol, and support for the pNFS SCSI layout."

An anonymous reader writes: Eleven years after Linus Torvalds developed Git after a falling out with BitKeeper for managing the Linux kernel source code, BitMover Inc has finally decided to open-source the BitKeeper VCS. The latest BitKeeper release has made the code open-source under the terms of the Apache 2.0 license. The community edition code is available from BitKeeper.org. Does BitKeeper now stand a chance against free software systems like Git and SVN?To offer some context, Larry McVoy, the CEO of BitMover -- the company that makes BitKeeper -- offered free BitKeeper licenses to various open source projects -- Linux kernel utilized it as well. However, later, Australian computer programmer Andrew Tridgell reverse engineered BitKeeper protocol in an attempt to make his own client. Torvalds didn't like this practice, and accused Tridgell of "playing dirty tricks with his proprietary source code tool of choice," and as a result, he wrote Git.

New to the Linux 4.6 kernel are a significant number of new features including NVIDIA GeForce GTX 900 open-source 3D support when using the closed-source firmware files, Dell XPS 13 Skylake laptop support, a fix for laptops that were limiting their own performance due to incorrectly thinking they were overheating, AHCI runtime power management support, Intel graphics power management features enabled by default, a new file-system (OrangeFS), and a range of other improvements.

AMD developers published initial open-source Linux driver support for Polaris GPUs with the addition adding over sixty-seven thousand lines of code to the Linux kernel. AMD Polaris graphics cards are expected this summer while AMD released the open-source driver support in advance for preparing their new Linux hybrid driver that relies upon the open-source AMDGPU kernel driver.

The cool Wine-related news of the week isn't just for Android Remix; an anonymous reader writes with some news applicable to a wider set of users: While no Windows-only Vulkan games have yet to be released, Wine developers are ready and have worked out experimental support for wrapping Vulkan Windows programs on Linux. Assuming you have a Vulkan Linux driver, the latest Wine-Staging build allows for Vulkan Windows programs/games to be dynanically translated and run on Linux 32-bit and 64-bit. Wine's Vulkan wrapper is passing all Khronos conformance tests, but hopefully the ever-expanding Linux game catalog will make this 10k+ lines of code not necessary moving into the future.

An anonymous reader writes: After being desired by NVIDIA Linux users for years, the proprietary GeForce graphics driver natively supports Wayland and Mir as an alternative to an X.Org Server. It's been a long time coming for the proprietary GPU driver stacks to support Wayland/Mir, but with today's 364.12 beta driver there is now the necessary DRM KMS kernel support and EGL extensions for being able to handle these next-generation display solutions. The new NVIDIA Linux driver also provides integrated Vulkan support, PRIME rendering support, and other additions.

An anonymous reader writes: AMD has finally published the previously talked about closed-source Radeon Vulkan driver for Linux. Announced by AMD via the Phoronix Forums is the new hybrid driver dubbed "AMD GPU-PRO Beta Driver – Linux." This closed-source user-space driver provides the first AMD Vulkan support on Linux along with OpenGL 4.5, OpenCL 2.0, and VDPAU video acceleration capabilities. But in using the open-source AMDGPU kernel driver, only the very latest AMD GPUs are currently supported (GCN 1.2+). Update: 03/19 03:22 GMT by T : Sorry for the borked link; now fixed.

An anonymous reader writes: There are unconfirmed reports that NVIDIA is working on its own Linux distribution dubbed "NLINUX." This NLINUX is supposedly a Linux platform optimized for gamers and similar to SteamOS, but NVIDIA has yet to confirm these reports and the sole evidence appears to be a circulating screenshot of an NLINUX install screen. Would you be interested in a Linux distribution created by an IHV? Somewhat similar is Intel's own Linux distribution, Clear Linux, that offers high performance Linux on Intel x86_64 hardware.

An anonymous reader writes: Ubuntu 16.04 LTS and newer will no longer be supporting AMD's widely-used Catalyst Linux (fglrx) driver. AMD has dropped support for this proprietary AMD driver in favor of encouraging users to use the open-source AMDGPU/Radeon drivers. While the fglrx/Catalyst driver is notorious among Linux gamers, this will represent a regression for many AMD Linux users due to the open-source driver only having OpenGL 4.1 support compared to OpenGL 4.5 in Catalyst, lower performance in common gaming workloads, incomplete OpenCL compute support, no CrossFire multi-GPU support, and other missing features. Much of the missing functionality will end up being implemented by AMD's new AMDGPU driver stack but that is still months away from being truly ready and will only benefit the very latest Radeon GPUs while the fglrx-free Ubuntu 16.04 is set to ship in April.

The Raspberry Pi 3 was found to be a faster upgrade compared to the Raspberry Pi 2, but the ODROID-C2 is a much faster alternative. For only $5 more than the Raspberry Pi 3, it includes twice the amount of RAM, Gigabit Ethernet, and a faster SoC. The ODROID-C2 also has HDMI 2.0 and superior Ethernet while the Raspberry Pi 3 has an advantage of 802.11n WiFi. The ODROID-C2 also has a heatsink for ensuring the SoC doesn't get as toasty as the Raspberry Pi 3.

An anonymous reader writes: There was much hope that Fedora 24 would be the first major Linux distribution using Wayland by default in place of an X.Org Server, that didn't pan out with Fedora 24 Workstation developers deciding not to use Wayland by default but it will remain a log-in time option. Fedora Wayland has made a lot of progress but functionality like on-screen keyboard, accessibility, remote displays, USB display hot-plugging, and other functionality is incomplete for the Fedora 24 timeline. At least there are many other Fedora 24 features that made it for this next release due out in June. Wayland will turn eight years old this year.
