Default The new --no-opengl-files flag in the 295.20 installer

What is its purpose?

Is this meant to be used with -x (extract only) or can the Nvidia driver now use Gallium for 3D?

Wouldn't it be smarter to just use the --opengl-prefix flag to avoid interfering with Gallium?

No, the NVIDIA driver still needs NVIDIA GLX and GL libraries in order for OpenGL to work.

The intention is to avoid clobbering existing GL/GLX libraries (such as Mesa/Gallium3D) that might be needed for a different (non-NVIDIA) GPU. This can be useful in settings where the NVIDIA GPU is not used for graphics at all. For example, using an NVIDIA GPU for CUDA/OpenCL on a system which already has a different GPU that is being used for graphics, including OpenGL.

Yes, if you want to install the NVIDIA GL libraries, but avoid conflict with an existing GL implementation, the --opengl-prefix flag works fine for that. This option isn't for that, though; it's for avoiding installation of GL libraries completely when they're not needed at all.

If this is intended for Optimus notebooks (afraid to say it?), Synergy, and multi-GPU desktops, a more suitable solution would be defaulting gl and xorg file placement to /usr/lib/nvidia-blah/.

It's not fun tearing apart your drivers and repacking them so they don't break our systems.
