Ubuntu 17.10 Artful Aardvark

Geplaatst op door

De gemiddelde Ubuntu-gebruiker, die halfjaarlijks wisselt van versie, komt voor het eerst in lange tijd voor een echte verrassing te staan: Unity is niet meer. In Ubuntu 17.10 met codenaam Artful Aardvark wordt Canonicals eigen desktopmanager Unity 7 volledig vervangen door Gnome 3.26, met enkele eigen tweaks voor de Ubuntu-feel. Ook moet de oude, vertrouwde Xorg-displayserver eraan geloven, al is het nog mogelijk om in te loggen met een Xorg-sessie, ook nodig voor sommige programmatuur. Lees verder →

Linux 4.13 Released, This Is What’s New

Geplaatst op door

Linux Kernel 4.13 is officially out!

Announcing the release on the Linux Kernel Mailing List (LKML) Linus Torvalds says: “last week was actually somewhat eventful, but not enough to push me to delay 4.13,” going on to recount some personal issues involving a kidney stone — ouch!

“Go get the new kernel,” he encourages.

The next release, Linux 4.14, will be a Long Term Support (LTS) release.

Linux 4.13 Features

Among the Linux 4.13 features you will find the following hardware and software improvements:

  • Initial Intel Cannonlake & Coffeelake support
  • HDMI 3D/stereoscopic support in Nouveau driver
  • DRM object sync support
  • Thunderbolt improvements
  • Support for the Retrode2 joypad adapter
  • Support for the Razer Atrox Arcade Stick
  • Support for ASUS Zen AIO MD-5110 keyboard
  • Improved Intel SST Atom support
  • Misc file system improvements for Brtfs, EXT4, F2FS and XFS
  • AppArmor code commits from Canonical

Each kernel update adds support for new ARM devices/boards/SoCs and Linux 4.13 is no exception. It adds support for the Bubblegum 96, the Rockchip RV1108 SoC, and many of the newer Orange Pi boards including the Orange Pi Win, Orange Pi Zero Plus 2, and Orange Pi Prime.

For a fuller look at everything that’s new in Linux Kernel 4.13 head over to the official mailing list announcement and follow the links.

Install Linux 4.13 on Ubuntu

Only the brave and foolish will want to upgrade to Linux 4.12 on Ubuntu right now as it requires the use of mainline Linux kernel builds intended for Ubuntu developers to use in debug and testing. Undeterred? The UUKU app makes it easy to install mainline Linux kernel on Ubuntu.

Ubuntu 17.10 will use the Linux 4.13 kernel by default, while this kernel (or later) will be back ported to Ubuntu 16.04 LTS in the next point release.

Ubuntu 17.10 Will Use GNOME Shell 3.26

Most of us expected that Ubuntu 17.10 would manage to with GNOME Shell 3.26 on board — but it’s nice to hear it confirmed.

A feature-freeze exception filed pending a package update last week has been approved, and now the first packages of GNOME Shell 3.26 are filtering out through the artful-proposed repository, ready for testing by users of the Ubuntu 17.10 daily builds.

“The Ubuntu Desktop Team wants to ship gnome-shell/mutter 3.26 with Ubuntu 17.10. The new version appears to improve responsiveness and has quite a few other improvements and tweaks,” the bug reads.

Ubuntu 16.04.3 LTS Released, Available to Download Now

Geplaatst op door

Ubuntu 16.04.3 LTS is now available to download.

It is the third point release in the Ubuntu 16.04 LTS series, and the second to be released this year.

Ubuntu 16.04.4 LTS will follow it early next year.

What is an Ubuntu point release?

Ubuntu LTS releases come with 5 years of ongoing package updates, bug fixes, hardware improvements, and security patches.

A point release is an updated version of the LTS installation image that rolls together all of these updates. This helps to reduce the number of packages and patches that a user has to download after installation. Lees verder →

Keep Your Nvidia Drivers Up-To-Date In Ubuntu Via PPA

Geplaatst op door
NVIDIA is well-known company all over the world which designs the graphics processing units (GPUs) for the gaming market, as well as system on a chit units (SOCs) for the mobile computing and automotive market. GPU-accelerated computing is the use of a graphics processing unit (GPU) together with a CPU to accelerate scientific, analytics, engineering, consumer, and enterprise applications. You are here most probably because you are a Linux user and you may have faced difficulties in past while installing GPU drivers, sometimes it is really difficult to configure manufacturer drivers for NVIDIA cards in Linux, there could be many reasons for this such as kernel upgrade, dependencies issue and so. By default Ubuntu use the open source video driver Nouveau for NVIDIA graphics card. This driver lacks support for 3D acceleration and may not work with the very latest video cards or technologies from NVIDIA. A proprietay alternative to Nouveau are the closed source unified NVIDIA drivers, which are developed by NVIDIA. This driver provides excellent 3D acceleration and video card support.

 

Nvidia Drivers Ubuntu

Release Highlights of 367.27 Drivers for Linux:

  • Added support for VDPAU Feature Set H to the NVIDIA VDPAU driver. GPUs with VDPAU Feature Set H are capable of hardware-accelerated decoding of 8192×8192 (8k) H.265/HEVC video streams.
  • Fixed a bug that caused the X server to sometimes skip displaying Vulkan frames when the Composite extension is enabled.
  • Fixed a bug that would cause OpenGL applications to crash when creating a context on one X display connection, then making it current with no associated drawable on another X display connection. This fixes a crash when starting some versions of Matlab.
  • Fixed OpenGL presentation to SDI through the GLX_NV_video_out and GLX_NV_present_video extensions, which was broken by the introduction of the nvidia-modeset kernel module in 358.09.
  • Fixed a bug that caused an incorrect offset to be applied when using the full composition pipeline on a display whose image has both a rotation and a ViewportOut offset applied.
  • Fixed a bug that could cause nvidia-settings to crash on some systems when responding to events such as hotplugging DisplayPort devices.
  • Fixed a bug that could cause crashes in OpenGL applications which use glTextureView() with a non-zero minlevel.
  • Enhanced the Display Device information page in nvidia-settings with additional information for DisplayPort devices to reflect attributes which are specific to DisplayPort connections.
  • Fixed a bug which could cause deleted application profiles to appear when editing rules in the nvidia-settings control panel.
  • Fixed a bug that caused hangs when a G-SYNC monitor is unplugged and a non-G-SYNC monitor is connected while G-SYNC is active.
  • Fixed a bug that caused “nvidia-modeset: ERROR: GPU:0: Activating G-SYNC failed” to be printed to the system log if a G-SYNC monitor is connected and stereo is enabled in xorg.conf on a configuration that doesn’t support it.
  • Added the NV_robustness_video_memory_purge OpenGL extension, which
  • allows applications to know when a mode switching or power event purged the contents of FBOs and BOs residing in video memory.
  • Fixed a bug that prevented HDMI 2.0 4K monitors from waking up from sleep or hot-replug.
  • Fixed a bug that could lead to a system crash if there was a peer-to-peer mapping still active during CUDA context teardown.

So there are two ways to install Nvidia drivers using the Ubuntu community PPA and make sure to read information on PPA page before you proceed to installation process. Run the following two commands in the terminal then follow any method to install Nvidia drivers in your system.

Linux-kernel 4.4 brengt 3d-versnelling naar virtuele desktop

Geplaatst op door

Linus Torvalds heeft versie 4.4 van de Linux-kernel zondagnacht vrijgegeven. De toevoeging van hardwarematige opensource 3d-ondersteuning voor virtuele Linux-desktops is een van de meest in het oog springende wijziging, naast veel verbeteringen voor amd-gpu’s.

Door de toevoeging van hardwarematige 3d-versnelling in de virtuele gpu-driver virtio-gpu benut de computer de grafische kaart efficiënt, waardoor bijvoorbeeld gebruikers een opengl-game kunnen spelen in een gevirtualiseerd Linux-systeem met de gpu-mogelijkheden van de host samen met QEMU 2.5. Een vorm van 3d-versnelling voor guests bestaat al veel langer in VirtualBox en VMWare, maar die virtualisaties zijn niet volledig opensource. Deze code werkt naast QEMU samen met Mesa.

Verder is ondersteuning voor AMD Stoney aan de kernel toegevoegd. Stoney is een toekomstige AMD-apu. Ook zijn er verschillende gpu-wijzigingen doorgevoerd voor bezitters van AMD Carrizo, Tonga of Fiji-gpu’s. Er is nog geen PowerPlay-ondersteuning, maar dat staat gepland voor de opensourcedriver in Linux 4.5.

Raspberry Pi-bezitters krijgen een Pi KMS-driver, waardoor de grafische capaciteiten van de Pi’s er op vooruitgaan. Hardwarmatige 3d-ondersteuning is nog niet in de kerneldriver gebouwd, maar Broadcom-ontwikkelaar Eric Anholt is daar volgens Phoronix nog druk mee bezig.

Nvidia-bezitters kunnen betere stabiliteit van de Nouveau-drivers verwachten en wat extra mogelijkheden voor verschillende klok-instellingen. Voor de GeForce GTX 900-serie ontbreekt hardwarematige versnelling nog in de opensourcedrivers.

Tevens voegt LightNVM ondersteuning toe voor open-channel-ssd’s. Open-channel-ssd’s zijn ssd’s die geen eigen firmware in de flash-translation-laag hebben ingebouwd, maar de fysieke solid-state-opslag aan het besturingssysteem overlaten. Overige wijzigingen hebben te maken met betere 64bit-ARM-ondersteuning en verbeteringen voor geheugengebruik bij Intel Skylake-processors. Ook binnen het netwerkapparaat is het een en ander gewijzigd, zo is er Very High Thoughput-ondersteuning voor mesh-netwerken toegevoegd en een nieuwe Realtek rtl8xxxu-wifi-driver. Een uitgebreide lijst wijzigingen is te vinden op kernelnewbies.org.
