· Fixed a regression in 256.29 where Performance Level clock
frequencies were reported incorrectly in nvidia-settings.
· Fixed a 3D Vision Stereo bug that caused the stereo glasses to not
toggle when the flat panel was not running at its native mode timings.
· Fixed a bug that caused nvidia-settings to crash when rendering
its thermal gauge widget if the range of valid values for the thermal
sensor was empty.
· Fixed a bug which prevented use of high performance PowerMizer
levels on systems with certain ACPI configurations.
· Fixed a bug that caused non-primary Fermi GPUs to fail to initialize
framebuffer memory. This caused a variety of symptoms, up to and
including system hangs.
· Added unofficial GLX protocol support (i.e., for GLX indirect
rendering) for the following OpenGL extensions:
· Improved Thermal Settings reporting in nvidia-settings to
accurately reflect hardware configurations with multiple thermal
· Fixed an interaction problem between Compiz and
'screen-scraping' VNC servers like x11vnc and vino that caused the screen
to stop updating.
Fixes Launchpad bug #353126.
· Enhanced VDPAU to add basic support for Xinerama. VDPAU will now
operate on a single physical X screen under Xinerama. See the
README for more details.
· Enhanced VDPAU's handling of corrupt clips of all formats on GPUs with
VDPAU feature set C to be at least as good as on GPUs with VDPAU
feature set B. This significantly improves various clips provided by
nvnews.net user eamiller.
· Fixed a bug in Xv attribute handling that caused hue, saturation,
brightness, and contrast values to be misapplied when using an
Xv overlay adaptor.
· Fixed a bug in the XvMC driver that prevented it from working on
systems with AGP graphics cards.
· Enhanced VDPAU to clear all VdpVideoSurfaces to black when allocated.
This provides more consistent results when using a surface as a
reference when no prior decode operation has written to that surface.
In turn, this improves the results of decoding some corrupt streams,
such as "p_only_no_play" from ffmpeg bug 1124.
· Implemented new APIs to allow sharing VDPAU surfaces with OpenGL and
CUDA. The OpenGL extension is GL_NV_vdpau_interop. For CUDA, please
see the documentation in the CUDA toolkit for details.
· Worked around a bug where the combination of a GPU with VDPAU feature
set A together with specific motherboard chipsets could cause visible
corruption when decoding some MPEG-2 streams
· Fixed a bug that prevented the VDPAU overlay-based presentation queue
from being used more than a few hundred times per X server invocation.
· Renamed the driver file libGLcore.so.VERSION to
libnvidia-glcore.so.VERSION, as a small step towards reducing the
filename collisions between NVIDIA's and Mesa's OpenGL implementations.
This driver file is used by NVIDIA's libGL.so and libglx.so, and
should never be used directly by applications.
· Changed the SONAME of libnvidia-glcore.so.VERSION,
libnvidia-tls.so.VERSION, and libnvidia-compiler.so.VERSION to be
".so.VERSION", rather than ".so.1". These driver files are only used
by other NVIDIA driver components, and are only intended to be used
by components of the matching NVIDIA driver version.
· Removed the "-pkg#" suffix from the NVIDIA Linux .run files.
The packages are now simply named "NVIDIA-Linux-ARCH-VERSION.run". On
Linux-x86_64, a package which omits the 32-bit compatibility libraries
is also available: "NVIDIA-Linux-x86_64-VERSION-no-compat32.run"
· Simplified the directory structure of the Linux extracted package;
most driver files are now just contained within the top level directory
of the package. Pass the '--list' option to the .run file for details.
· Removed precompiled kernel interfaces from the NVIDIA Linux-x86 .run
file; these were ancient and had not been updated in years. Going
forward, NVIDIA does not plan to provide precompiled kernel interfaces
with the Linux .run files. However, nvidia-installer and the .run
file will retain the ability for users to add their own precompiled
kernel interfaces via the '--add-this-kernel' .run file option.
· Compressed the nvidia-settings, nvidia-installer, and nvidia-xconfig
tarballs with bzip2, rather than gzip.
