How to remove or hide top bar on Jetson nano Ubuntu 18.04.

I want hide top menu bar.

and I try many methods.

  1. gnome-tweaks : Althought install gnome-shell-extension-autohidetopbar, I can’t find topbar tab in gnome-tweaks
  2. vi /usr/share/gnome-shell/theme/ubuntu.css : add bottom

#panel, #panel * {
height: 0px;
color: rgba(0,0,0,0);

but i can’t hide Top bar.

Install some extra extension may be helpful

sudo apt-get install gnome-shell-extensions
sudo apt-get install gnome-shell-extension-autohidetopbar

->reboot device
-> click on the tweak-tool -> extensions-> hidetopbar

Thank you reply.

I succeeded in hiding the top bar.

However, there is a lower workspace bar.

How can I hide this?

You can try “vanilla” Gnome which doesn’t have one:

sudo apt install gnome-session

I also suggest turning animations off in tweak-tool.

I am not familiar enough with Canonical’s customisations to know how to turn off the bottom bar. (I haven’t used it long enough to even recall there being one. I’ve always disliked Unity).

After installing you can switch between the desktops at the login screen by clicking on the cog icon.
