Hi,
I follow this link (How to remove or hide top bar on Jetson nano Ubuntu 18.04.)
and install the extension,
sudo apt-get install gnome-shell-extensions
sudo apt-get install gnome-shell-extension-autohidetopbar
->reboot device
-> click on the tweak-tool -> extensions-> hidetopbar
but the Desktop looks bad, how can I restore back to the original Desktop?
I have tried to turn off the extension Applications>SystemTools>Tweaks>Extensions, bad no luck.
Thx
