======== Release 302 Entries ========
* 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.
