Plattner outlined some of the driver features currently not possible under Wayland/XWayland for workstation users due to the lack of support by Wayland compositors and/or the existing Wayland protocols. As such, there are currently no plans to support them for (X)Wayland use. Among those features not planned include:
- Stereo rendering using GLX / EGL / Vulkan.
- Implicit SLI Mosaic mode.
- The nvidia-settings utility with the same level of configuration support under X11. This comes down to the lack of cross-compositor display configuration support.
But via Vulkan Direct to Display code there are plans for stereo rendering with Vulkan, Vulkan explicit SLI via the VK_KHR_device_group extension, swap groups via VK_NV_present_barrier, and frame lock and genlock support.
Some of the other features planned for future NVIDIA driver releases with Wayland support include:
- Multi-monitor VRR.
- nvidia-drm fbdev=1 by default.
- nvidia-drm modeset=1 by default.
- Display muxes for laptops.
- Advanced display pipeline features.
- Front-buffer rendering in GLX with XWayland.
- NVIDIA DRM Presentation Timing.
- VDPAU support on Wayland.
- vGPU support on Wayland.
