Arrow 256.25 (beta) for Linux x86/x86_64 released

  • Added unofficial GLX protocol support (i.e., for GLX indirect rendering) for the following OpenGL extensions:
    • GL_ARB_blend_func_extended
    • GL_ARB_draw_buffers_blend
    • GL_ARB_sample_shading
    • GL_ARB_timer_query
    • GL_EXT_draw_buffers2
    • GL_EXT_separate_shader_objects
    • GL_NV_explicit_multisample
    • GL_NV_transform_feedback
  • Improved Thermal Settings reporting in nvidia-settings to accurately reflect hardware configurations with multiple thermal sensors.
  • 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.
The 256.25 NVIDIA Accelerated Linux Graphics Driver Set for Linux/x86 is available for download via FTP and HTTP.
The 256.25 NVIDIA Accelerated Linux Graphics Driver Set for Linux/x86_64 is available for download via FTP and HTTP.
(note: The HTTP links currently have "-pkg#" suffixes despite the note above. I'm trying to get that corrected).

Please see the README (x86 / x86_64) for more information about this release.

Please note: This NVIDIA Linux graphics driver release supports GeForce 6xxx and newer NVIDIA GPUs, GeForce4 and older GPUs are supported through the 96.43.xx and 71.86.xx NVIDIA legacy graphics drivers. GeForce FX GPUs are supported through the 173.14.xx NVIDIA legacy graphics drivers.

Please also note: If you encounter any problems with the 256.25 NVIDIA Linux graphics driver release, please start a new thread and include a detailed description of the problem, reproduction steps and generate/attach an nvidia-bug-report.log.gz file (please see http://www.nvnews.net/vbulletin/showthread.php?t=46678 for details).
