Common Pitfalls
1
One common pitfall is assuming that the open-source kernel modules will work seamlessly with older NVIDIA GPUs.
Users with pre-Turing GPUs must continue using closed-source modules, so it's essential to verify GPU compatibility before installation.
2
Another pitfall is the potential mismatch between the open-source kernel modules and user-mode stacks.
All components of the driver stack must match versions within a release, so users should ensure they are using compatible versions to avoid issues.
