WARNING: An NVIDIA kernel module 'nvidia' appears to be already loaded in your kernel.  This may be because it is in use (for example, by an X server, a CUDA program, or the NVIDIA Persistence Daemon), but this may also happen if your kernel was configured without support for module unloading.  Some of the sanity checks that nvidia-installer performs to detect potential installation problems are not possible while an NVIDIA kernel module is running.
-> Would you like to continue installation and skip the sanity checks? If not, please abort the installation, then close any programs which may be using the NVIDIA GPU(s), and attempt installation again. (Answer: Abort installation)
ERROR: Installation has failed.  Please see the file '/var/log/nvidia-installer.log' for details.  You may find suggestions on fixing installation problems in the README available on the Linux driver download page at www.nvidia.com.
