-u NONE:
no vimrc hence 'compatible' mode unless also -N
no gvimrc
no plugins

-N
use 'nocompatible' mode even if no vimrc

neither
use vimrc from usual location if found
'nocompatible' if found, else 'compatible'
in gvim only, use gvimrc from usual location if found
use global plugins from $VIMRUNTIME/plugin/
(and other plugin/ subfolders of 'runtimepath' folders)

'compatible' influences a lot of other options (see :help 'compatible'),
see if your vimrc sets any of those and how (and see also :help :verbose)

Check also near the top of the output of :scriptnames — maybe you
unwittingly have a system vimrc (a vimrc without . or _ in front of its
name, usually in $VIM but on Unix sometimes in /etc/ — the exact
location is displayed about one-third of the way down from the top of
the output of :version)

The people of Halifax invented the trampoline. During the
Victorian period the tripe-dressers of Halifax stretched tripe across a
large wooden frame and jumped up and down on it to `tender and dress'
it. The tripoline, as they called it, degenerated into becoming the
apparatus for a spectator sport.

The people of Halifax also invented the harmonium, a device for
castrating pigs during Sunday service.
