Disable vim automatic visual mode on mouse select

issue: :set mouse-=a
add to ~/.vimrc: set mouse-=a

my ~/.vimrc for preserving global defaults and only changing one option:

source $VIMRUNTIME/defaults.vim
set mouse-=a

None of this was working for me without skip_defaults_vim, which disables other things I wanted. But looking up defaults.vim
https://github.com/vim/vim/blob/6c1afa3d0bdfce3ac1197b00409ac1afa7cf368a/runtime/defaults.vim#L80-L81

... the intent of the vim authors is just type : and visual selection is disabled! That's a start.

then I noticed, near the top of the file, the recommended way to revert settings is :set option&. So if I use set mouse& instead of set mouse-=a now things work as described. VIM - Vi IMproved 9.0 (2022 Jun 28, compiled May 04 2023 10:24:44)

on debian 11 we're now using the following /etc/vim/vimrc.global to disable the mouse integration by default for all users:

unlet! skip_defaults_vim
source $VIMRUNTIME/defaults.vim
let skip_defaults_vim=1
set mouse&

without @TheSpyder's hint, it didn't work with "set mouse=-a".. so thank you very much :D!

Thank you. The trick is to disable the mouse support for Vim. I achieved this by adding the following to the /etc/vim/vimrc file.
I had to add syntax on to enable syntax highlighting.

set mouse=
