This is what I'm getting when trying to compile either nvidia 185 or the 190 drivers. Could it be same as audio hard ware not being detected?
Kernel module compilation complete.
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), or NVIDIA GPU
installed in this system is not supported by this NVIDIA Linux graphics
driver release.
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.
