Release highlights for 195.30:
- Fixed a performance regression with non-antialiased text in KDE4.
- Enabled GPU acceleration for many RENDER compositing operations that were previously processed in software, including conjoint and disjoint blending modes and component alpha blending.
- Added experimental GPU acceleration of the RENDER CompositeTrapezoids operation. This can be enabled at runtime by running:
nvidia-settings -a AccelerateTrapezoids=1
This is only supported on the GeForce GTX series or newer products.
- Fixed a bug in the VDPAU overlay-based presentation queue that caused high CPU usage during "put bits" operations when more than two surfaces were queued.
- Updated `nvidia-settings --query all` to report all available attributes queryable through all NV-CONTROL target types.
Release highlights for 195.22:
- Enhanced the VDPAU blit-based presentation queue to provide values of "first_presentation_time" that have less jitter.
- Add support for R16F and RG32F GLXFBConfigs when using GeForce 8 series and higher GPUs.
- Added support for A2BGR10 32-bit GLX visuals on 30-bit X screens. These allow some level of window transparency when using 30-bit visuals with GLX and Composite, but they may cause problems with older X servers and/or applications. ARGB GLX visuals can be disabled by adding:
Option "AddARGBGLXVisuals" "False" to the X configuration file.
- Fixed a problem that caused DisplayPort devices to behave incorrectly when DPMS power saving mode was triggered.
- Updated VDPAU to improve thread concurrency. See the README for details.
- Altered NVIDIA X driver behavior in the case that no display devices are connected to the GPU. Previously, in this case, the NVIDIA X driver would pretend a CRT was connected to the GPU. Now, the NVIDIA X driver will not automatically pretend that any CRTs are connected. If the X driver does not detect any connected display devices, the X server will fail to start.
To restore the old behavior, use the ConnectedMonitor X configuration option; e.g.,
Option "ConnectedMonitor" "CRT" Alternatively, if display is not desired, Quadro and Tesla GPU users can enable "NoScanout" mode, which bypasses any mode timing validation or use of display devices; this is configured with:
Option "UseDisplayDevice" "none"
- Disabled software cursors when the driver is operating in "no scanout" (UseDisplayDevice "none") mode. The software cursor image is not visible in remote desktop applications or screenshots anyway, so having software cursor enabled was unnecessary.
- Changed glXSwapBuffers() behavior for a pixmap such that it is now a no-op in the direct rendering case in order to match the indirect case and comply with the GLX spec. Previously, calling glXSwapBuffers() on pixmaps in the direct case would swap the pixmap's buffers if the pixmap was double buffered.
- Modified the installation location and names of internal VDPAU libraries to conform to conventions and Debian packaging guidelines. New versions of libvdpau expect this layout. Compatibility with old versions of libvdpau is maintained with symlinks.
- Fixed a bug that could cause errors in graphical applications run after a previous application using VDPAU and OpenGL. This behaviour was observed when running Gwenole Beauchesne's hwdecode-demos application.
- Modified vdpau.h to increment VDPAU_VERSION, to reflect the fact that new features have been added in the past. Also, add the new define VDPAU_INTERFACE_VERSION.
- Fixed a periodic temporary hang in the VDPAU blit-based presentation queue.
- Fixed a problem that caused resolution limitations or corruption on certain DisplayPort devices such as the Apple 24" Cinema display or some DisplayPort to VGA adapters.
- Disabled the UseEvents option for GeForce 8 series and higher GPUs due to a problem that causes occasional short hangs. It will be re-enabled when that bug has been tracked down and fixed.
- VDPAU now allows multiple streams to be decoded at once, without the need to set any environment variables.
NVIDIA Accelerated FreeBSD Graphics Driver Set for FreeBSD/i386
is available for download via FTP
Please see the README
for more information about this release.
If you are using FreeBSD 6.0-RELEASE
or a more recent FreeBSD 6.x
release, please make sure that the compat5x-i386
package is installed.
Note that the gtk-2.x ports package(s) shipped with FreeBSD releases > 5.3-RELEASE
are binary incompatible with those shipped with FreeBSD 5.3-RELEASE
; due to this, the `nvidia-settings`
binary shipped with 195.30
will not work on FreeBSD > 5.3-RELEASE
. This problem can be solved by (re-)building `nvidia-settings`
# fetch ftp://download.nvidia.com/XFree86/nv...-195.30.tar.gz
# tar zxf nvidia-settings-195.30.tar.gz
# cd nvidia-settings-1.0# gmake
# install nvidia-settings /usr/X11R6/bin
This NVIDIA FreeBSD graphics driver release supports GeForce 6 series and newer
NVIDIA GPUs. GeForce FX GPUs are supported through the 173.14.xx
driver series, while GeForce4 and older GPUs are supported through the 96.43.xx
NVIDIA legacy graphics drivers.
Please also note:
