  • Why libinput doesn't have a lot of config options

    Most days, at least one of the bugs I deal with requests something along the lines of "just add $FOO as a config option". In this post, I'll explain why this is usually a bad solution. First, read http://www.islinuxaboutchoice.com/ and keep those arguments in mind. Generally, there are two groups of configuration options - hardware options and user options. Hardware options are those that deal with specific quirks needed on some hardware, but not on other hardware. User options are those that deal with user preferences such as tapping or two-finger vs. edge scrolling.

  • Libinput Adds A Touchpad Software Middle Button

    Red Hat's Peter Hutterer explained in a blog post, "I just pushed a patch to libinput master to enable a middle button on the clickpad software buttons. Until now, our stance was that clickpads only get a left and right software button, split at the 50% mark. The reasoning is simple: touchpads only have markings for left and right buttons (if any!) and the middle button's extents are not easily discoverable if there is no visual or haptic feedback...So the patch I just pushed out to master enables a middle software button between the left and the right button. The exact width of the button scales with the touchpad but it's usually around 20-25mm and it's centered on the touchpad so despite the lack of visual or haptic guides it should be reliable to hit. The new behaviour is hard-coded and for now middle button emulation continues to work on touchpads."

Graphics/Benchmarks
Linux

Today, April 6, 2016, Nvidia has released a new Beta video driver for GNU/Linux and UNIX operating systems, version 364.15, which fixes a few bugs and adds a couple of improvements.

According to the release notes, Nvidia 364.15 Beta Linux driver adds support for Nvidia Quadro M6000 24GB GPU (Graphics Processing Unit) and fixes multiple issues with the EGL driver, which should improve the resizing of windows in the Wayland display server.

  • Intel's Unreleased 3.0 X.Org Driver Gets More Fixes For DRI3/Present

    In addition to the X.Org Server still seeing DRI3 and Present extension fixes, the xf86-video-intel and xf86-video-ati DDX drivers for X.Org have also been seeing more DRI3/Present fixes recently.

    In particular, much of the work recently on the still unreleased xf86-video-intel 3.0 driver has been about Direct Rendering Infrastructure 3 and the Present extension. It's going on three years that the Intel 3.0 X.Org driver has been in development without being formally released and there's still no signs of it coming soon. The most recent development release, xf86-video-intel 2.99.917, is now 15 months old itself!

  • Nouveau Kepler On Linux 4.6 vs. NVIDIA's 364 Proprietary Driver

    We've already looked at the GeForce 900 series performance on Nouveau with the Linux 4.6 kernel that finally has the necessary bits for supporting 3D hardware acceleration on these Maxwell GPUs. Those GTX 900 series results didn't end up being particularly exciting since there isn't yet any re-clocking support on this open-source NVIDIA Linux driver. For complementing those results are some GeForce 600/700 "Kepler" graphics card results when comparing Nouveau on Linux 4.6 with Mesa 11.3-devel and using re-clocking then compared to the latest NVIDIA proprietary driver.

  • Nouveau NVC0 Adds ETC2/ASTC Texture Compression For Newer GPUs

    Back in December a patch rolled out for supporting ETC2 and ASTC texture compression by the Nouveau NVC0 Gallium3D driver. Today that patch was finally merged for benefiting newer NVIDIA GPUs.

    With the commit that landed there is now ETC2 and ASTC texture compression support for the GK20A (Tegra K1) graphics processor as well as the GTX 750 "GM107" graphics processors and newer.

  • CSS: Revolutionizing the Appearance of the WWW

    Upon further inspection of the original Compiz code and the default configuration, resize is blocked from triggering the effect. Applying this to the updated effect code resolved the issue for the time being.

    As a bonus, a small issue encountered during the very early stages of the project was the velocity from the initial placement of the window creating some even more interesting animations:

  • OpenChrome Version 0.4.0 is almost ready
  • Mesa 11.2.0 release candidate 4
  • Initial support for ARM Mali Display Processors
  • Collaboration on standard Wayland protocol extensions

    It's almost the Year of Wayland on the Desktop(tm), and I have reached out to each of the projects this message is addressed to (GNOME, Kwin, and wayland-devel) to collaborate on some shared protocol extensions for doing a handful of common tasks such as display configuration and taking screenshots. Life will be much easier for projects like ffmpeg and imagemagick if they don't have to implement compositor-specific code for capturing the screen!

  • Wobbly Windows Support & Other Post-Processing Effects For Wayland

    Samsung developers have been working on implementing client-side post processing effects for Wayland. This is to achieve similar effects like "wobbly windows" as were common to the Linux desktop going back many years with AIGLX / Compiz / Beryl.

    Samsung's Derek Foreman and Mike Blumenkrantz have been working on a "Wayland Wobbly Windows" protocol that exposes when clients are being moved and when they're being dragged in order to implement different graphical effects.

“LEDE” OpenWrt fork promises greater openness

A “Linux Embedded Development Environment” (LEDE) fork of the lightweight, router-oriented OpenWrt Linux distribution vows greater transparency and inclusiveness. Some core developers of the OpenWrt community has forked off into a Linux Embedded Development Environment (LEDE) group. LEDE is billed as both a “reboot” and “spinoff” of the lightweight, router-focused distribution that aims to build an open source embedded Linux distro that “makes it easy for developers, system administrators or other Linux enthusiasts to build and customize software for embedded devices, especially wireless routers.” Read more
