Canonical Reportedly Not Planning To Enable Wayland-By-Default For Ubuntu 20.04 LTS
Since the short-lived Ubuntu 17.10 GNOME + Wayland experience, the Ubuntu desktop has still been using the trusted X.Org Server session by default. While Ubuntu 19.04 will soon be shipping and the Ubuntu 19.10 development cycle then getting underway, don't look for any Wayland-by-default change to be around the corner.
Twice in the past week I've received communication from two indicating that Canonical reportedly isn't planning on enabling Wayland-by-default for Ubuntu 20.04 LTS. If Canonical were planning to go ahead with Wayland used by default, they would need to make the change for Ubuntu 19.10 as is customary for them to make large changes in the LTS-release-1 version in order to facilitate more widespread testing ahead of the Long Term Support cycle. But Canonical engineers feel that the Wayland support isn't mature enough to enable in the next year for Ubuntu 20.04 LTS.

Vulkan Working To Expose Video Encode/Decode, Machine Learning
During this week's Game Developers Conference was the usual Khronos Dev Day where Vulkan, WebGL, glTF, and OpenXR took center stage. During the Vulkan State of the Union some details on their future endeavors were covered.
Among some of the larger efforts that are "in flight" are improving the portability of Vulkan to closed platforms without native drivers (MoltenVK, etc), continuing to work on ray-tracing (complementing the existing VK_NV_ray_tracing), exposing video encode/decode through Vulkan, exposing machine learning capabilities, and the separate effort on safety critical Vulkan.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
