XRGEARS: Infamous "Gears" Now On VR Headsets With OpenHMD, Vulkan
Well, the virtual reality (VR) demo scene is now complete with having glxgears-inspired gears and Utah teapot rendering on VR head mounted displays with the new XRGEARS.
Kidding aside about the gears and teapot, XRGEARS is a nifty new open-source project with real value by Collabora developer Lubosz Sarnecki. XRGEARS is a standalone VR demo application built using the OpenHMD initiative for tracking and Vulkan for rendering. XRGEARS supports both Wayland and X11 environments or even running off KMS itself. This code also makes use of VK_EXT_direct_mode_display with DRM leasing.

Arcan versus Xorg – Approaching Feature Parity
This is the first article out of three in a series where I will go through what I consider to be the relevant Xorg feature set, and compare it, point by point, to how the corresponding solution or category works in Arcan.
This article will solely focus on the Display Server set of features and how they relate to Xorg features, The second article will cover the features that are currently missing (e.g. network transparency) when they have been accounted for. The third article will cover the features that are already present in Arcan (and there are quite a few of those) but does not exist in Xorg.

Arcan Display Server Is Nearing Feature Parity With The X.Org Server
The Arcan display server, which started off years ago sounding like a novelty with being a display server built off a game engine in part and other interesting features, is nearing feature parity with the X.Org Server.
While most hobbyist display server projects have failed, Arcan has continued advancing and with an interesting feature set. Recently they have even been working on a virtual reality desktop and an interesting desktop in general. Arcan is getting close to being able to offering the same functionality as a traditional X.Org Server.
If you are interested in a lengthy technical read about the differences between Arcan and X.Org, the Arcan developers themselves did some comparing and contrasting when it comes to the display support, windowing, input, font management, synchronization, and other areas.
