nvidia-inst is a helper script from EndeavourOS to help installing nvidia-dkms and other needed packages plus some basic configs to set… nvidia-dkms is one of the packages that you need to install for nvidia drivers to work… aside from nvidia-utils… the dkms version is buidling modules needed against kernel updates automatically what is usefull and safe in cases… and also will make sure you have modules build for other kernels automatic without the need to manually install them.
long story short…
install nvidia-inst script and run it will do the trick in most cases.
you can test it before without installing to check the output for errors:
nvidia-inst -t
and if it runs without error run it for real: nvidia-inst as a command inside a terminal…
and you are right: nvidia-inst --32 to install the 32libs with it… or to test nvidia-inst --32 -t
