NVIDIA has released new beta display drivers for Linux

Release highlights since 430.40:

Fixed a bug which caused the kernel to panic when exiting a single X server when multiple X servers were active and in an SLI configuration.
Fixed a regression introduced in the 430.* series of releases that caused a segmentation fault in libnvcuvid.so while using Video Codec SDK APIs on certain graphics boards.
Added initial experimental support for runtime D3 (RTD3) power management on Turing notebook GPUs.
Improved nvidia-bug-report.sh to collect runtime D3 (RTD3) power management information.
Improved nvidia-bug-report.sh to collect ACPI tables when the acpidump tool is available.
Added Vulkan and OpenGL+GLX support for PRIME render offload. Please see the PRIME Render Offload chapter in the README for system requirements and configuration details.
Added support for changing Digital Vibrance in the display controls section of nvidia-settings on Turing hardware.
Fixed the cuvidParseVideoData API in the NVCUVID driver to correctly propagate errors returned by the PFNVIDSEQUENCECALLBACK callback function to the application.
Fixed a bug that caused the NVIDIA X driver to behave incorrectly or crash when a client queried Xinerama information on X servers with a non-NVIDIA X screen as screen 0.
Fixed the "Image Settings" options in the "OpenGL Settings" page of nvidia-settings for Quadro GPUs. Previously, OpenGL rendering on Quadro would behave as if the "High Quality" option were selected regardless of the selection. Now, the setting will default to "High Quality" for Quadro but selecting a lower option will affect rendering accordingly. (Other GPUs are unchanged: the default remains "Quality", but other options can be selected if desired.)
Fixed a bug that could cause Vulkan applications to generate spurious warning messages about a missing NV-GLX extension.
Removed the non-GLVND OpenGL libraries from the NVIDIA Linux driver installation package. The GLVND OpenGL libraries were introduced in release 361.16, and have been installed by default since release 364.12, with the non-GLVND versions available as an alternative via the "--no-glvnd-glx-client" and "--no-glvnd-egl-client" installer options. As the non-GLVND libraries are no longer included in the installation package, these options will no longer have any effect.
Fixed a bug that prevented nvidia-drm from marking preferred modes properly when reporting display information via the DRM-KMS API.
Updated nvidia-installer to make compiler mismatches non-fatal when adding precompiled kernel interfaces to an installer package using the "--add-this-kernel" option, to be more consistent with the behavior when installing without precompiled interfaces.
Fixed the NvEncodeAPI driver to correctly reject the encoding of sequences with resolutions smaller than what the NVENC supports.
Fixed display color range handling on pre-Turing GPUs, such that when limited color range is selected through the display controls page in nvidia-settings, output pixel values will be correctly clamped to Consumer Technology Association (CTA) range.
