NVIDIA has released new 440.26 Beta Linux Display Drivers

RELEASE HIGHLIGHTS

Updated the confirmation dialog box that is displayed when quitting the nvidia-settings control panel to report when there are pending configuration changes which will be lost if they are not applied or saved before quitting.

Enabled parallel GLSL shader linking by default; i.e., allow GL_ARB_parallel_shader_compile to work without first calling glMaxShaderCompilerThreadsARB().
Added support for HDMI 2.1 variable refresh rate (VRR) G-SYNC Compatible monitors on supported GPUs.For more details, see "Configuring Multiple Display Devices on One X Screen" in the README.
Added support for the GLX_NV_multigpu_context and GL_NV_gpu_multicast extensions.For more details, see the "Configuring SLI and Multi-GPU FrameRendering" chapter of the README, and the extension specifications:

Fixed a bug that prevented Vulkan applications running on systems configured for SLI. Vulkan applications can now run while SLI is enabled; however, they will only be able to use a single GPU.
Simplified the nvidia-sleep.sh sample script to no longer depend on unreliable detection of the current VT through X server logs.
Added EGL support for PRIME render offload. Please see the PRIME Render Offload chapter in the README for configuration details.
Fixed a regression introduced in 435.19.02 that would cause some applications which use the VK_KHR_DISPLAY extension to result in a segmentation fault.
Enabled HardDPMS by default. See the README entry on the X configuration option "HardDPMS" for more information.
Fixed a bug which caused corruption in the following DXVK titles:

Saints Row IV
Saints Row: The Third

Added VP9 decode support to the NVIDIA VDPAU driver. See the VDPAU Support appendix in the README for supported VP9 decoder profiles.
Fixed a bug that could cause heapUsage values reported by VK_EXT_memory_budget to not immediately update after vkFreeMemory was called.
Changed GPU clock management strategy to more quickly ramp down clocks after a drop in GPU utilization.
Added X configuration option, "SidebandSocketPath", which controls the directory in which the X driver will create a pathname UNIX domain socket used to communicate with the NVIDIA OpenGL, Vulkan and VDPAU driver components.
The X driver will now create a fallback pathname UNIX domain socket in the directory specified by the "SidebandSocketPath" option, or /var/run by default, which will be used by other NVIDIA driver components if they are unable to connect to the default abstract socket.This fixes a bug where graphics applications run within a network namespace (which prevents the use of abstract sockets) were unable to take advantage of some driver features, such as G-Sync.
Fall back to system memory when video memory is full for some driver-internal allocations. This can help fix Xid 13 and Xid 31 cases in Vulkan applications when video memory is full.
Fixed a bug that could cause a blank screen on some DisplayPort monitors when logging in to GNOME, if the nvidia-drm kernel module parameter modeset=1 is specified.
Fixed a bug that prevented NVIDIA GPUs from entering the low-power D3 state when entering suspend-to-idle (s2idle). Note that on some systems this may expose an existing timing issue in the Linux kernel; see the "Known Issues and Workarounds" section of the "Configuring Power Management Support" chapter of the README for more details.
