NVIDIA Drivers

The proprietary NVIDIA drivers do not work out of the box on PREEMPT_RT kernels, such as ours. They must be patched to take into account the fact that PREEMPT_RT changes spinlocks in a way the NVIDIA drivers can't handle.

First, download the following:


Edit the nvidia-rt-installer.sh script to change the first three variables to match your system:

  • VER should correspond to the output of 
  $ uname -r
  • NVIDIA_INSTALLER should correspond to the package you downloaded from NVIDIA, minus the ".run" extension
  • KERNEL_SRC_DIR should be the directory of the kernel source you just installed the ChronOS kernel from
