I want to know how to disable mouse wheel, however I found this and this question and I have tried put them to my .vimrc:
set mouse=""
map <ScrollWheelUp> <nop>
map <S-ScrollWheelUp> <nop>
map <ScrollWheelDown> <nop>
map <S-ScrollWheelDown> <nop>
But none of them will disable the mouse wheel, I still can use it to scrolling.
And I'm on Arch Linux, using vim 7.4 with gnome-terminal 3.16.2.
It is probably a gnome-terminal problem and not a Vim one. With your .vimrc as it is, you can turn on and off the mouse wheel by issuing these commands in terminal
echo -e '\e[?1000h'
echo -e '\e[?1000l'
Edit: Previous answer doesn't work because gnome-terminal settings are overridden by settings of Cinnamon (in this case), and maybe also because the scrolling was done using a touchpad and not a mouse. It is possible to disable scrolling with help of Synclient (command line utility to configure and query Synaptics driver settings) putting
augroup scroll
au!
au VimEnter * :silent !synclient VertEdgeScroll=0
au VimLeave * :silent !synclient VertEdgeScroll=1
augroup END
in your .vimrc.
This solution is not optimal for disabling scrolling even outside of Vim for as long as Vim runs.
