Ubuntu – I hate the three horizontal bars on top. Any idea on how to reduce or merge them like ubuntu 16

20.04

I'm on ub20LTS and I really dislike how much top space the topmost bars use.
Any idea on how to remove or reduce their numbers? PIC

Edit: Thanks to everybody's support, thishere is how my workspace looks like now. I've :

  1. Installed gnome-extensions for firefox.
  2. Turned off menu bar in ff.
  3. Installed dash to dock.
  4. Installed hide top bar.

This way you can better utilize your screen space.

Best Answer

There are several options.

1) Use the Pixel saver extension.

This extension will remove the legacy titlebar when an application is maximized. This will work nicely for Firefox, Libreoffice and any other application that uses legacy titlebars.

Pixel saver extension

  1. Install the extension with the command sudo apt install gnome-shell-extension-pixel.
  2. Enable the extension using Gnome Tweaks or Extensions. Both are not installed by default, but can be installed with the command 1 sudo apt install gnome-tweaksorsudo apt install gnome-shell-extension-prefs`.

2) Hide the top bar

Hide the top bar. Then, only the chrome of your applications will be visible.

Install the extension: sudo apt install gnome-shell-extension-autohidetopbar. Enable the extension as outlined under 1).

You can combine this with option 1) to further increase vertical screen real estate.

3) Install Dash to Panel

You currently have launchers on the bottom. The extension Dash to Panel will combine these launchers with the elements of the top bar (application menu, clock, status menu, ...) into one bottom bar.

To install the extension, install gnome-shell-extension-dash-to-panel and enable it as described under 1).

You can go a step further and combine this extension with the "Pixel saver" extension to remove the title bar at the top when the application is full screen.

4) Only for Firefox: disable the titlebar

This removes the titlebar in Firefox only. Head to the menu (☰) and select Customize. In the left bottom corner, turn "Title bar" off.
