I followed the advice from this solution(Note the comment as well) to get the 2x2 grid back:
Can I have 2x2 workspaces in GNOME 3?
When I go into the tweak tool and up the number to 9 workspaces it saves and throws no error. But when I try and use the workspaces I am stuck with a 3x2 grid.
Any suggestions? Thanks!
