nvidia-graphics-drivers-450 (450.57-0ubuntu0~0.18.04.1) bionic; urgency=medium

  * New upstream release:
    - Added support for Vulkan direct-to-display on DisplayPort
      displays which are connected via DisplayPort Multi-Stream
      Transport (DP-MST).
    - Added a new documentation file, supported-gpus.json, which
      exposes a machine-readable list of supported GPUs and features.
    - Added an implementation of glNamedBufferPageCommitmentARB,
      which was missing 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
      running under Wayland.
    - Fixed a bug that could cause some Swap Group configurations to
      present at half of the display refresh rate.
    - Added a new Connector-N display connector name alias type, with
      a unique alias 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's
      NVFBC_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, has been 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
      descriptors when destroying Vulkan instances.
    - Added a fallback presentation path for PRIME Render Offload
      configurations 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 the stride parameter for some VkDescriptorType values.
    - Fixed a bug causing the Plasma desktop panel to freeze when
      compositing 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
      flipping due 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
      for flipping Vulkan applications. In particular, this fixes
      screen-scraping tools such as VNC and import.
    - Removed libnvidia-fatbinaryloader.so from the driver package.
      This functionality is now built into other driver libraries.
    - Extended the dynamic runtime power management support in the
      NVIDIA driver 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 for communication 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 by the x86-video-amdgpu driver as PRIME display offload
      sinks.
    - Added support for displays connected to NVIDIA GPUs to act as
      PRIME display 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
      large cursor images with PRIME display offloading.
    - Fixed an interaction problem with 5.4 and newer Linux kernels
      that caused a performance regression when allocating system
      memory.
    - Fixed a driver installation failure on Linux kernel 5.8 release
      candidates, 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 release
      candidates, where the NVIDIA kernel module failed to build with
      error "too many arguments to function '__vmalloc'".
