I’m getting error while installing NVIDIA driver in parrot OS

Answer 1

First install bumblebee and then go for it.
Nvidia would work only for 3d graphics controller and for default display driver you will have to suffer with integrated driver like intel, as far I know.

Answer 2

Call your sysadmin for this. Or you want to write nvidia driver yourself? Then learn C language

Answer 3

this is not related to programming.
are you installing it from repo or downloaded from Nvidia website.
and what is the error?
