How do I turn off minimize-on-click option for Ubuntu dock?
Solution 1:
You can revert to the default option by running
gsettings reset org.gnome.shell.extensions.dash-to-dock click-action
Also try running
gsettings range org.gnome.shell.extensions.dash-to-dock click-action
then you'll get all possible values that can be set. See if you find another option preferable.
Solution 2:
Use:
gsettings set org.gnome.shell.extensions.dash-to-dock click-action 'minimize-or-overview'
This does exactly what you want it to do.
