32-bit distributions with 64-bit kernels
Some distributions have the option of installing a 64-bit kernel for use with all 32-bit userspace programs. This configuration is not supported by the NVIDIA Linux Graphics Driver. If you try to install the 64-bit driver package on such a system, you will receive an error like the following:
./nvidia-installer: No such file or directory
If you have this configuration, use your distribution's package manager to install a 32-bit kernel and then install the 32-bit version of the NVIDIA Linux Graphics Driver.
