Last year NVIDIA began publicly outlining known Wayland limitations for their driver and future support plans. This week NVIDIA put out updated information concerning known gaps in Wayland support as well as their ongoing future driver plans for enhancing the feature compatibility under this X11 successor.
NVIDIA published a new forum post concerning the Wayland driver support as of their current R575 driver series. This aims to address common questions and known issues as it concerns feature parity between X11 and Wayland for their packaged driver stack.
Among the NVIDIA Wayland-related driver plans still being pursued are enabling the NVIDIA DRM modeset mode by default, better handling multi-GPU laptops with display multiplexers, advanced display pipeline features, Presentation Timing information for the NVIDIA DRM driver, enabling vGPU support on Wayland, and enabling VDPAU video acceleration support on Wayland.
Meanwhile for stereo rendering, Vulkan explicit SLI, swap groups, and frame lock / genlock support on Wayland the Vulkan Direct to Display functionality via the VK_KHR_display extension will be used.
Features not planned to be supported by NVIDIA on Wayland include stereo rendering for GLX / EGL / Vulkan, implicit SLI Mosaic mode, and some NVIDIA Settings UI panel features not being available.
More details on these NVIDIA Wayland driver support plans and feature parity to X11 via NVIDIA’s Developer Forums.
