I used this method in 18.04 (https://joshtronic.com/2017/07/26/hide-title-bars-in-gnome-shell/) but it doesn't working now... Any ideas?
P.S. I used a standard desktop environment
P.P.S. To be more precise: I used to have a clean terminal without ANY bars, status bars, borders etc. in any window size and I am trying to achieve this again in new ubuntu 20.04.
