FreeBSD Display Driver – x86

• Fixed a bug that caused OpenGL programs to leak file descriptors when calling exec() on themselves.
• 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.

Installation instructions: Once you have downloaded the driver, change to the directory containing the driver package and install the driver by running, as root, tar xzf NVIDIA-FreeBSD-x86-302.07.tar.gz && cd NVIDIA-FreeBSD-x86-302.07 && make install
Then, edit your X configuration file so that the NVIDIA X driver will be used; this can normally be done by running nvidia-xconfig

Note that the list of supported GPU products is provided to indicate which GPUs are supported by a particular driver version. Some designs incorporating supported GPUs may not be compatible with the NVIDIA Linux driver: in particular, notebook and all-in-one desktop designs with switchable (hybrid) or Optimus graphics will not work if means to disable the integrated graphics in hardware are not available. Hardware designs will vary from manufacturer to manufacturer, so please consult with a system's manufacturer to determine whether that particular system is compatible.
