ERROR: The Nouveau kernel driver is currently in use by your system.  This driver is incompatible with the NVIDIA driver, and must be
       disabled before proceeding.  Please consult the NVIDIA driver README and your Linux distribution's documentation for details on
       how to correctly disable the Nouveau kernel driver.


WARNING: One or more modprobe configuration files to disable Nouveau are already present at:
         /usr/lib/modprobe.d/nvidia-installer-disable-nouveau.conf, /etc/modprobe.d/nvidia-installer-disable-nouveau.conf.  Please be
         sure you have rebooted your system since these files were written.  If you have rebooted, then Nouveau may be enabled for other
         reasons, such as being included in the system initial ramdisk or in your X configuration file.  Please consult the NVIDIA
         driver README and your Linux distribution's documentation for details on how to correctly disable the Nouveau kernel driver.


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.
