NVIDIA has released new 450.57 Linux Display Drivers.
Release Highlight
Added support for Vulkan direct-to-display on DisplayPort displays whichare connected via DisplayPort Multi-Stream Transport (DP-MST).
Added a new documentation file, supported-gpus.json, which exposes amachine-readable list of supported GPUs and features.
Added an implementation of glNamedBufferPageCommitmentARB, which wasmissing from the NVIDIA driver's support for the GL_ARB_sparse_buffer extension.
Fixed a bug that could cause a KDE Plasma session to crash when runningunder Wayland.
Fixed a bug that could cause some Swap Group configurations to presentat half of the display refresh rate.
Added a new Connector-N display connector name alias type, with a uniquealias assigned to each physical display connector on a GPU. See the README for more information.
Fixed a bug that prevented X11 EGL displays from being reinitialized.
The 450 driver series is the last that supports NvFBC'sNVFBC_CAPTURE_TO_HW_ENCODER capture interface, which has been deprecated since NVIDIA Capture SDK 6.0 released in 2017. Future NVIDIA drivers after the 450 series will return NVFBC_ERR_UNSUPPORTED if that capture interface is requested. The recommended way to encode captured frames with NVENC is by using the NVIDIA Video Codec SDK. See: https://developer.nvidia.com/nvidia-video-codec-sdk
Implemented support for NVIDIA NGX. A new library, libnvidia-ngx.so, hasbeen added to support the new functionality. This new library is needed by applications which link against any of the following SDKs:
NVIDIA DLSS SDK
NVIDIA NGX SDK
Fixed a bug which caused Vulkan applications to leak file descriptorswhen destroying Vulkan instances.
Added a fallback presentation path for PRIME Render Offloadconfigurations where the DRI3 and/or Present extension are unavailable.
Fixed a bug where vkCreateSampler would fail with no borderColor data,even though it wasn't needed.
Fixed a bug where vkUpdateDescriptorSetWithTemplate would ignore thestride parameter for some VkDescriptorType values.
Fixed a bug causing the Plasma desktop panel to freeze whencompositing is disabled ( https://bugs.kde.org/show_bug.cgi?id=353983)
Improved Vulkan device enumeration under an X.Org X server environment.See the "Known Issues" in the README for more information.
Fixed a visual glitch of Vulkan applications when they stop flippingdue to a window change, such as when alt-tab is used to change window focus.
Fixed a bug where XGetImage requests would return stale data forflipping Vulkan applications. In particular, this fixes screen-scraping tools such as VNC and import.
Removed libnvidia-fatbinaryloader.so from the driver package. Thisfunctionality is now built into other driver libraries.
Extended the dynamic runtime power management support in the NVIDIAdriver to shut off power to video memory under certain conditions. See the chapter titled "PCI-Express Runtime D3 (RTD3) Power Management" in the README for more information.
Added HEVC 10/12 bit "decode only" support to the NVIDIA VDPAU driver. Note that VDPAU's presentation pipeline and OpenGL-VDPAU interop does not support 10- and 12-bit video surfaces yet. See the "VDPAU Support" appendix in the README for supported HEVC decoder profiles.
Added support for Image Sharpening for OpenGL and Vulkan applications
Added new VdpYCbCrFormats VDP_YCBCR_FORMAT_Y_U_V_444_16,VDP_YCBCR_FORMAT_P010 and VDP_YCBCR_FORMAT_P016 for accessing 16-bit surfaces via VdpVideoSurfaceGetBitsYCbCr() and VdpVideoSurfacePutBitsYCbCr() in the NVIDIA VDPAU driver.
Added support to create 16-bit video surfaces in the NVIDIA VDPAU driver.
Modified nvidia-persistenced and libnvidia-ml (NVML) to use libtirpc forcommunication instead of relying on the deprecated glibc RPC implementation.
Enabled GPU screens by default on X.Org xserver version 1.20.7 and higher.
Fixed a bug where rendering in a separate user namespace (unshare -U)would show black window and produce Xid 13 errors.
Removed support for "IgnoreDisplayDevices" X configuration option.
Added support for PRIME Synchronization when using displays driven bythe x86-video-amdgpu driver as PRIME display offload sinks.
Added support for displays connected to NVIDIA GPUs to act as PRIMEdisplay offload sinks, also known as "Reverse PRIME". See the chapter titled "Offloading Graphics Display with RandR 1.4" in the README for additional information.
Removed 'libGL.la' libtool archive from the install package.
Fixed a bug that caused a brief orange flash on some platforms when a
display mode is being set.
Fixed a bug that could cause the X server to crash when using largecursor images with PRIME display offloading.
Fixed an interaction problem with 5.4 and newer Linux kernels that causeda performance regression when allocating system memory.
Fixed a driver installation failure on Linux kernel 5.8 releasecandidates, where the NVIDIA kernel module failed to build with error "'struct mm_struct' has no member named 'mmap_sem'".
Fixed a driver installation failure on Linux kernel 5.8 releasecandidates, where the NVIDIA kernel module failed to build with error "too many arguments to function '__vmalloc'".
