Arrow 302.07 (beta) for Linux x86/x86_64 released

Release highlights since 295.40:
  • Fixed a bug that caused OpenGL programs to leak file descriptors when calling exec().
  • Fixed rendering corruption at the start of new X server generation.
  • Added X driver support for RandR 1.2 and RandR 1.3. See "Support for the X Resize and Rotate Extension" in the README for details.
  • Extended the MetaMode X configuration option syntax with the following new attributes:
    • Rotation : specifies the display device's rotation
    • Reflection : specifies the display device's reflection
    • Transform : specifies a 3x3 transformation matrix to be applied to the display device
    • ViewPortOut : specifies the region of the mode in which to display pixels
    • ViewPortIn : specifies the size of the region in the X screen to display in the ViewPortOut

    For example, "DFP-0: nvidia-auto-select { Rotation=left }". See "Configuring Multiple Display Devices on One X Screen" in the README for details.
  • Removed the TwinView X configuration option; the functionality it provided is now enabled by default.

    Previously, the NVIDIA X driver only enabled one display device for an X screen unless TwinView was enabled. Now, the NVIDIA X driver enables, by default, as many display devices as the GPU supports driving simultaneously. To limit how many display devices are driven by an X screen, use the UseDisplayDevice X configuration option.
  • Added a CurrentMetaMode attribute to the nvidia-settings command line, to query and set the current MetaMode.

    As an example, these two commands are equivalent:

    xrandr --output DVI-I-2 --mode 1280x1024 --pos 0x0 --output DVI-I-3 --mode 1920x1200 --pos 1280x0

    nvidia-settings --assign CurrentMetaMode="DVI-I-2: 1280x1024 +0+0, DVI-I-3: 1920x1200 +1280+0"

  • Removed overscan compensation configurability from NV-CONTROL and nvidia-settings. This can be configured, with finer granularity, through the ViewPortIn and ViewPortOut MetaMode attributes. See "Configuring Multiple Display Devices on One X Screen" in the README for details.
  • Altered mode validation such that for digital display devices the X driver only allows, by default, modes which are reported in the EDID. Previously, the NVIDIA X driver allowed other modes, but implicitly scaled those other modes to one of the EDID modes.

    Now, only the modes in the EDID are validated and the X driver does not do any implicit scaling. Any desired scaling can be configured explicitly through the new ViewPortIn and ViewPortOut MetaMode attributes. See "Configuring Multiple Display Devices on One X Screen" in the README for details.
  • Removed Flat Panel Scaling configurability in nvidia-settings. Any desired scaling can be configured through the new ViewPortIn and ViewPortOut MetaMode attributes.
  • Hotplug events (specifically, the RRNotify_OutputChange RandR event) are now generated when display devices are connected and disconnected from the GPU. Many desktop environments automatically resize the X desktop in response to these events.
  • Added display device name aliases, such that X configuration options that use display device names can refer to a display device by one of several names, including the RandR Output name for the display device. The X log reports the list of aliases for each display device.
  • Updated EDID parsing to include more complete support for EDID 1.4 and more recent versions of CEA-861.
  • Removed the Rotate X configuration option. This was used to statically rotate the X screen. Its functionality is replaced by the Rotation MetaMode attribute and RandR 1.2 rotation support. See the README for details.
  • Removed the RandRRotation X configuration option. This enabled configurability of X screen rotation via RandR 1.1. Its functionality is replaced by the Rotation MetaMode attribute and RandR 1.2 rotation support. See the README for details.
  • Removed support for the following NV-CONTROL attributes:
    • NV_CTRL_GPU_SCALING
    • NV_CTRL_GPU_SCALING_DEFAULT_TARGET
    • NV_CTRL_GPU_SCALING_DEFAULT_METHOD
    • NV_CTRL_DFP_SCALING_ACTIVE
    • NV_CTRL_GPU_SCALING_ACTIVE
    • NV_CTRL_FRONTEND_RESOLUTION
    • NV_CTRL_BACKEND_RESOLUTION
    • NV_CTRL_OVERSCAN_COMPENSATION
    • NV_CTRL_FLATPANEL_BEST_FIT_RESOLUTION
  • Improved rendering performance for RENDER bitmap text.
  • Enabled the OpenGL "Sync to VBlank" option by default.
  • Added a new option, --restore-original-backup, to nvidia-xconfig. nvidia-xconfig creates a backup of the original X configuration file when modifying an X configuration file that does not appear to have been previously modified by nvidia-xconfig. This option restores a backup of the original X configuration file, if such a backup is found.
  • Expose the following additional FSAA modes via NV-CONTROL, nvidia-settings, and through X visuals and GLXFBConfigs:
    • 16X multisample FSAA on all GeForce GPUs
    • Coverage sample FSAA on G80 and above GeForce GPUs
    • 32X multisample FSAA on G80 and above Quadro GPUs
    • 64X multisample FSAA on Fermi and above Quadro GPUs
  • Enabled conformant texture clamping by default in OpenGL.
  • Removed support for the GVO Clone mode NV-CONTROL attributes:
    • NV_CTRL_GVO_DISPLAY_X_SCREEN
    • NV_CTRL_GVO_X_SCREEN_PAN_X
    • NV_CTRL_GVO_X_SCREEN_PAN_Y
  • Added a new, higher resolution icon for nvidia-settings.
  • Updated the NVIDIA X driver's handling of X configuration options that affect an entire GPU, not just a particular X screen running on a GPU (e.g., NoPowerConnectorCheck): for such X configuration options, the X driver will now honor the option on any of the X screens configured on the GPU. Prior to this change, the NVIDIA X driver only honored such options on the first X screen configured on a GPU.
  • Added a checkbox to nvidia-settings to control the texture clamping attribute. When the box is checked, OpenGL textures are clamped according to the OpenGL specification. When it is unchecked, GL_CLAMP is remapped to GL_CLAMP_TO_EDGE for borderless 2D textures.
  • Removed the "Display" and "X Screen" tabs from the "X Server Display Configuration Page" of nvidia-settings, and added a new "Selection" dropdown menu for selecting X screens or display devices. This makes it easier to select X screens/Displays that are hidden.
  • Fixed a problem where starting, stopping, and moving OpenGL application windows was very slow on Quadro FX 4600, Quadro FX 5600, GeForce 8800 GTX, GeForce 8800 GTS, and GeForce 8800 Ultra.
  • Fixed an OpenGL performance regression which affected Geforce 6 and Geforce 7 series integrated GPUs.
