Full stop. > Again incorrect the documentation for the nVidia driver even discusses how to set up CUDA here are two of the relevant quotes from it: "Disabling acceleration is useful when another component, such as CUDA, requires exclusive use of the GPU's processing cores. Performance of the X server will be reduced when acceleration is disabled, and some features may not be available." "The NVIDIA driver will not perform any mode validation or mode setting for this X screen. This is intended for use in conjunction with CUDA or in remote graphics solutions such as VNC or Hewlett Packard's Remote Graphics Software (RGS)." >From an article on the release of 12.0-BETA4 ( https://www.phoronix.com/scan.php?page=news_item&px=FreeBSD-12.0-Beta-4): "This is necessary for FreeBSD 64-bit CUDA support with NVIDIA's driver. Previously the FreeBSD CUDA support played nicely with 32-bit, but that was dropped in CUDA 9.0. This should help too for other 64-bit Linux emulation code for working with NVIDIA's binary graphics driver." -- Aryeh M. Friedman, Lead Developer, http://www.PetiteCloud.org
