How do I disable window move with alt + left mouse button in GNOME Shell?

First of all, install dconf-tools .

To do that, run the following command:

sudo apt-get install dconf-tools

Then open it, Alt+F2 → dconf-editor.

Scroll down to org → gnome → desktop → wm → preferences → mouse-button-modifier → Set it to whichever key you like.

enter image description here

Or, equivalently,

gsettings set org.gnome.desktop.wm.preferences mouse-button-modifier "<Super>"

in the terminal. (This requires neither dconf-editor, nor dconf-tools Install dconf-tools )

Warning: Setting it to nothing means that all clicks move windows, instead of disabling it!

Use the Tweak Tool (gnome-tweak-tool):

Windows > Window Action Key

In Mint(or Cinnamon) the key can be changed or disabled under

system settings > windows > behavior > 'Special key to move and resize window'

I have it set to the super/windows key instead.
