Default Re: chmod 0666 /dev/nvidia* chown root /dev/nvidia*

What "chown" and "root" mean?

"chown" is the UNIX command for changing the "owner" of the file. The first octal in the permissions number gives the permissions of the user or UID (user ID) set as "owner".

Compare to "chgrp", which sets the "group" the file belongs to.

"root" is the all-powerful God-user of UNIX systems. It is akin to the Administrator user on modern Windows systems. It has a UID of 0 and a GID of 0.
