No se instala ese driver oficial de Nvidia

ERROR: Unable to load the kernel module 'nvidia.ko'.  This happens most
       frequently when this kernel module was built against the wrong or
       improperly configured kernel sources, with a version of gcc that differs
       from the one used to build the target kernel, or if a driver such as
       rivafb/nvidiafb is present and prevents the NVIDIA kernel module from
       obtaining ownership of the NVIDIA graphics device(s).
       
       Please see the log entries 'Kernel module load error' and 'Kernel
       messages' at the end of the file '/var/log/nvidia-installer.log' for
       more information.
