Uncompressing NVIDIA Accelerated Graphics Driver for Linux-x86_64 430.50

  WARNING: nvidia-installer was forced to guess the X library path
           '/usr/lib64' and X module path '/usr/lib64/xorg/modules'; these
           paths were not queryable from the system.  If X fails to find the
           NVIDIA X driver module, please install the `pkg-config` utility and
           the X.Org SDK/development package for your distribution and
           reinstall the driver.


  Install NVIDIA's 32-bit compatibility libraries?
  # select [Yes] on here
     Yes                                    No

  Would you like to run the nvidia-xconfig utility to automatically update
  your X configuration file so that the NVIDIA X driver will be used when you
  restart X?  Any pre-existing X configuration file will be backed up.
  # select [No] on here
     Yes                                    No
