NVIDIA reveal a list of issues with their driver and Wayland


Whereas the state of affairs has improved just a little for NVIDIA and Wayland, there not likely there but and so NVIDIA are actually conserving a public record of the problems break up between drivers and both protocol or compositor limitations. This follows on from the massive splash they made just lately with their new open supply Linux GPU kernel modules, which additionally improved Wayland assist just a little too with the 515.43.04 driver that went up on the similar time.

NVIDIA mentioned they anticipate the record to get shorter over time as “lacking performance is carried out each within the driver and in upstream elements”.

So for these , here is issues as they stand proper now:

NVIDIA DRIVER LIMITATIONS


  • The VDPAU library, used for {hardware} accelerated video decoding and presentation, doesn’t have native Wayland assist and doesn’t work with Xwayland.

  • The NvFBC desktop seize library doesn’t have native Wayland assist and doesn’t work with Xwayland.

  • Variable show refresh price capabilities resembling G-Sync should not reported by nvidia-drm module, subsequently this performance just isn’t accessible on Wayland.

  • Digital actuality shows, such because the SteamVR platform, require assist for DRM show leasing which doesn’t at present work.

  • EGL_EXT_platform_x11 just isn’t supported with Xwayland.

  • The nvidia-drm module doesn’t assist the GAMMA_LUT, DEGAMMA_LUT, CTM, COLOR_ENCODING, or COLOR_RANGE connector properties, which can affect some compositor options associated to paint correction.

  • The nvidia-settings configuration device has restricted performance on Wayland.

  • Entrance-buffer rendering in GLX doesn’t work with Xwayland.


WAYLAND PROTOCOL OR COMPOSITOR LIMITATIONS


  • The next workstation options should not supported by any Wayland compositors or the Wayland protocol. They may even possible require new EGL extensions or different means to show the associated {hardware} performance.



  • There isn’t a established public API by way of which Wayland compositors can energy off video reminiscence by way of RTD3.

  • Xwayland doesn’t present an acceptable mechanism for our driver to synchronize software rendering with presentation, which may trigger visible corruption in some circumstances.

  • Show multiplexers (muxes) are usually utilized in laptops with each built-in and discrete GPUs to offer a direct connection between the discrete GPU and the built-in show (inside mux) or an exterior show (exterior mux). On X11, the show mux might be robotically switched when a full-screen software is operating on the discrete GPU, enabling enhanced show options and improved efficiency, however no Wayland compositors at present assist this performance.

  • Oblique GLX doesn’t work with Xwayland as a result of the Glamor rendering engine just isn’t appropriate with our EGL implementation.

  • {Hardware} overlays can’t be utilized by GLX functions with Xwayland.
