X.Org Server 1.21's XWayland implementation has added support for the xdg-output-unstable-v1 version 3 protocol to help the likes of KDE and compositors like Sway based on WLROOTS.

While atomic mode-setting has been around for several years now and to provide a modern mode-setting interface that can test modes prior to the actual operation and reduce possible flickering during mode-setting events and also being faster, the common xf86-video-modesetting driver has at least temporarily disabled the support by default.

The VKMS virtual kernel mode-setting driver is seeing support for PRIME import added to it so this software solution can be used for helping to test multi-GPU PRIME configurations on Linux even without the hardware attached.

Adding to the changes to find with the eventual X.Org Server 1.21 release is a change from Red Hat that has been carried by Red Hat Enterprise Linux and Fedora for years.

Version 1.14 of the libinput library for unified input handling on Linux X.Org and Wayland systems is now available.

We're less than two months out until the annual X.Org Developers' Conference (XDC) and the featured presentations for this three-day event have now been announced.

In addition to the Intel DRM driver landing lots of feature code into DRM-Next for the Linux 5.4 kernel cycle coming up in September, the DRM-Misc-Next crew for collecting core infrastructure changes and work to the smaller Direct Rendering Manager drivers has also been seeing new 5.4 work.

It's vintage X.Org driver week... Not only was there an S3 display driver update for that vintage hardware, but a SiS X.Org display driver update has also been released.

S3 Graphics drivers are still alive and well on Linux, well, sort of. On Thursday was the first new open-source xf86-video-s3 driver update in seven years.

Linux input expert Peter Hutterer of Red Hat shipped the much anticipated release candidate today for libinput 1.14, the open-source input handling library used by both X.Org and Wayland systems.

Longtime X.Org developer Alan Coopersmith who also maintains the X.Org stack for Oracle's Solaris has been trying to get out some updated X.Org modules with different code-bases having collected enough changes over the years to warrant new versions.

The 2019 X.Org Developers Conference for "all-things open-source graphics" is coming up at the start of October. But if you've been wanting to talk about something related to the Linux kernel, Mesa, Wayland, or related components, this week is your last chance to apply.

With the Fedora Workstation 31 feature outlook covered earlier this week, there was an interesting comment in that article by Red Hat's Christian Schaller that deserves special coverage.

With no X.Org Server 1.21 release being imminent, Red Hat's Adam Jackson today issued xorg-server 1.20.5 as a very small point release to the existing 1.20 stable series.

Merged this week to the X.Org Server code-base was an EGL-based GLX provider for helping XWayland and allowing some games to run nicely now under this X11 code-path for Wayland compositors. While not yet merged, another interesting bit of XWayland code is now under review as a merge request.

A notable improvement was merged into the "xserver" Git tree for the eventual X.Org Server 1.21 release that will improve the support for various Linux games relying on XWayland for running under a Wayland compositor.

X.Org's annual event, the X.Org Developers' Conference, is running like a well-oiled machined these days. While there are still months to go until XDC2019 in Montreal, a Call for Proposals has been issued for those wishing to speak at this annual gathering that pertains to Wayland, Mesa, libinput, Cairo, and related components as well, yes, the X.Org Server.

Work by NVIDIA to provide separate per-client vendor mappings for GLXVND were merged to X.Org Server 1.21 Git as another step towards improving the PRIME GPU offloading support when multiple GPU drivers are at play.

While formally the X.Org Server aimed to put out a new feature update every six months, in recent years they have been well off that trajectory with not much feature activity going on especially now that GLAMOR / XWayland / xf86-video-modesetting have stabilized and many Linux distributions eyeing Wayland by default. But there is now at least some little bit of interest in what's going into X.Org Server 1.21.

NVIDIA has been working on a new GLX extension to help the PRIME GPU offloading situation where multiple GPU vendors are involved and thus different OpenGL driver implementations. In particular, the proposed GLX_EXT_server_vendor_select is designed to better fit in to address PRIME GPU offloading obstacles introduced by their work on the now common GLVND OpenGL Vendor Neutral Dispatch library.

While there were the recent X.Org Foundation board elections, a do-over was needed as their new custom-written voting software wasn't properly recording votes... So here's now your reminder to re-vote in these X.Org elections.

We haven't been seeing as much GLAMOR activity these days but then again the pace of X.Org Server development has certainly slowed up in recent years. GLAMOR as a reminder allows for X.Org Server 2D acceleration to happen in a generic manner via OpenGL / GLES and has been a common area for improvement.

During this year's X.Org Foundation elections there was the key ballot initiative on whether the X.Org Foundation should formally accept FreeDesktop.org into its umbrella. That measure, which required a super majority of members to approve, passed. But the X.Org Foundation Board of Directors voting hit an oops.

While X.Org and FreeDesktop.org are already closely related, administered by many of the same people, and FreeDesktop.org provides the hosting for much of the infrastructure, there isn't many formalities around FreeDesktop.org and the X.Org Foundation formally doesn't have control of FreeDesktop.org. But there's now a vote on whether the X.Org Foundation will formally accept FreeDesktop.org.

The X.Org Foundation is once again participating in the Google Summer of Code where student developers engage with various open-source efforts on a range of projects. If there are interested and capable participants, GSoC 2019 could bring a Vulkan settings/preferences user-interface for the Mesa drivers, new OpenMAX acceleration bits, and other possible initiatives.

NVIDIA's Andy Ritger has contributed a simple yet long overdue addition to the X.Org Server with the new "NoOutputInitialSize" option.

While X.Org Server 1.20.4 was just released a few days ago with XWayland improvements and more, for vintage computer enthusiasts there is now the X.Org Server 1.19.7 that was released independently to provide a six for helping out the SiS 6326. Yes, the graphics processor from 1998.

For those wanting a nostalgic X11 experience this weekend, the X11 Display Manager (XDM) has seen its first release since 2011.

Adam Jackson of Red Hat has issued the X.Org Server 1.20.4 point release with the latest stable updates primarily consisting of XWayland enhancements.

It shouldn't come as a surprise with X11R7.7 being the last "katamari" release and it having debuted back in 2012, but no further "bundled" releases of X.Org are planned.
