Debian 10 :

vi /usr/share/vim/vim81/defaults.vim

Debian 11 :

vi /usr/share/vim/vim82/defaults.vim

Commenter les lignes suivantes, comme ceci :

" In many terminal emulators the mouse works just fine. By enabling it you
" can position the cursor, Visually select and scroll with the mouse.
"if has('mouse')
" set mouse=r
"endif
