How to hide top bar in Ubuntu 18.04?
How can I hide top bar in Gnome 3.28 Ubuntu 18.04?
How can the hide-top-bar extension be installed?
First open the terminal and install chrome-gnome-shell
package:
sudo apt install chrome-gnome-shell
Then install one of these extensions:
GNOME Shell integration for Chrome
GNOME Shell integration for Firefox
GNOME Shell integration for Opera
Finally, head over to the GNOME Extensions page for the "Hide Top Bar" extension and enable the ON/OFF switch for the extension to install.
For reference, install gnome-tweaks and run:
sudo apt install gnome-shell-extension-autohidetopbar
Then log out and back in. The option to auto hide the top bar will be available from gnome-tweaks tool in the extensions section.
The simplest and working way I found is to install the Dash-to-Panel GNOME extension. Works like a charm.
Dash to Panel Extension
You can toggle it from the browser itself.
I was having the same problem about removing top bar. What I do is hack into the theme css, and edit it in place.
Edit /usr/share/gnome-shell/theme/ubuntu.css, add to the bottom
#panel, #panel * {
height: 0px;
color: rgba(0,0,0,0);
}
The top bar is there, but won't be visible and can't interact with user.
