https://bugzilla.redhat.com/show_bug.cgi?id=1271401Fixed a regression from 358.09 that caused G-SYNC monitors configured to use 3D Vision stereo to go blank and report an unsupported signal. Fixed a regression from 358.09 that caused OpenGL applications that failed to negotiate permission to perform glXSwapBuffers via flipping to stop updating the screen. This was triggered on Fedora 22 where the SELinux system policy prevents gnome-shell from communicating with the X server.
- The OpenGL Vendor-Neutral Driver (GLVND) infrastructure is now included and supported by the NVIDIA GLX and OpenGL drivers. This should not cause any visible changes in behavior for end users, but some internal driver component libraries have been renamed and/or moved as a result. These changes may affect scripts that rely on the presence of NVIDIA OpenGL driver components other than those specified in the Linux OpenGL ABI version 1.0, maintainers of alternative NVIDIA driver installation packages, and applications which rely on the presence of any non- OpenGL/GLX symbols in the libGL.so.1 library and its dependencies in any way.
For more information on the GLVND project.
The Linux OpenGL ABI version 1.0 specification is available at:
- Updated nvidia-installer to run ldconfig(8) and depmod(8) after uninstalling an existing driver, instead of only running these two commands when installing a new driver.
- Removed the VDPAU wrapper and trace libraries libvdpau.so.1 and libvdpau_trace.so.1 from the driver package. These libraries may be available via your distribution's package management system, or can be compiled from the sources available at:
http://freedesktop.org/wiki/Software/VDPAU/ for more information.
Now, OpenGL applications that fail to negotiate flipping will fall back to glXSwapBuffers via blitting.

Fixed a regression that reduced OpenGL performance on headless X server configurations. Fixed a memory leak that occurred after destroying a GLXWindow which still has the current context attached to it. Fixed a bug which caused EGL pbuffers to be created with both a front and back buffer, instead of a back buffer only, as is required for EGL. Added a new kernel module, nvidia-modeset.ko. This new driver component works in conjunction with the nvidia.ko kernel module to program the display engine of the GPU.
nvidia-modeset.ko does not provide any new user-visible functionality or interfaces to third party applications. However, in a later release, nvidia-modeset.ko will be used as a basis for the modesetting interface provided by the kernel's direct rendering manager (DRM).
Reduced flickering and delays when transitioning into or out of G-SYNC mode. As part of this change, monitors that have G-SYNC indicators in their on-screen displays will now always report that they are in G-SYNC mode. The OpenGL G-SYNC visual indicator can be enabled in nvidia-settings to determine when G-SYNC is actually being used. GLX protocol for the following OpenGL extension from OpenGL 3.0 has been promoted from unofficial to ARB approved official status:

With the above changes, GLX protocol for OpenGL 3.0 has been promoted from unofficial to ARB approved official status.
Added a new system memory allocation mechanism for large allocations in the OpenGL driver. This mechanism allows unmapping the allocation from the process when it is not in use, making more virtual address space available to the application. It is enabled by default on 32 bit OpenGL applications with Linux 3.11+ and glibc 2.19+. Memory allocated this way will consume space in /dev/shm. Setting the environment variable __GL_DevShmPageableAllocations to 2 will disable this feature Added support for OpenGL 4.3. Added support for X.Org xserver ABI 20 (xorg-server 1.18).
