Linux, Solaris, and FreeBSD driver 440.26 [beta release] [long-lived branch release]

Release highlights since 435.21:

  • 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.
