Ubuntu 20.04 introduces new dark mode in the Settings utility. It is however not full dark when you turn it on in Gnome Shell.

System tray menu, top-bar calendar, notification popups, and desktop context menu are not dark but always light when you switching between light, dark, and standard modes.

Enable Full Dark Theme in Ubuntu 20.04:

1.) First install user themes Gnome Shell extension.

It was able to install the extension simply via Ubuntu Software when I was in Ubuntu 18.04. Ubuntu 20.04 however shows me “No Application Found” when I searching for user themes in the new Ubuntu Software (Snap Store).

  • As a workaround, open Firefox web browser and go to https://extensions.gnome.org:

    Click the link text “click here to install browser extension” and follow the pop-ups to install the browser extension:

    shell browser extension

  • Then open terminal via Ctrl+Alt+T and run command:
    sudo apt install chrome-gnome-shell

  • Finally go to https://extensions.gnome.org/extension/19/user-themes/.

    Turn the switch on and then select install the Gnome Shell extension:

    User Themes extension

2.) Install Gnome Tweaks if you have it.

sudo apt install gnome-tweaks

3.) Finally launch Gnome Tweaks and navigate to Appearance in the left pane, choose Yaru-dark as the Shell theme and done!

And of course select Dark in System Settings -> Appearance to get dark applications if you don’t have it.

This tutorial is going to show Ubuntu begginers how to enable Gnome’s default left panel (Dock), which has an auto-resize panel height.

In Ubuntu 18.04 and higher, the left panel (called Dock) is by default extended to all the available screen height, which looks just like it does in the previous default Unity desktop.

While the Settings utility only offers options to toggle auto-hide, icon size, and panel position, here’s how to enable auto-resize panel height (or width if panel moved to bottom).

1.) First search for and install dconf editor in Ubuntu Software.

2.) Launch dconf editor, and navigate to org/gnome/shell/extensions/dash-to-dock.

Scroll down and find the line says “extend-height” and turn off the switch.

In addition, for those familiar with Linux command line, open terminal (Ctrl+Alt+T) and run single command to do the job:

gsettings set org.gnome.shell.extensions.dash-to-dock extend-height false

And restore the change via command:

gsettings set org.gnome.shell.extensions.dash-to-dock extend-height true

Feel that Gnome desktop ‘Alt+Tab’ popup is slow? There’s by default 0.15 second popup delay when you pressing Alt+Tab on keyboard.

It’s nothing serious for some people including me. But if you want to remove the delay to speed up task switcher popup, it can be done easily via gnome shell extension.

Open Ubuntu Software, search for remove alt tab popup and install the extension.

It takes effect immediately after you installed the extension. And as noted it effects all kinds of pop-ups.

To manage the Gnome Shell extension, install and open Gnome Tweaks, then go to Extensions tab.

In Ubuntu 18.04 and higher, Gnome’s built-in screen keyboard can be enabled via universal access menu.

However, it only triggers automatically in Gnome Activities and Application menu, nowhere else. See the bug. Though it’s marked as fixed, I still have the problem in my laptop.

For those have the same issue, you can install the previous Ubuntu 16.04’s default onboard screen keyboard utility in Ubuntu 18.04 as a workaround.

Open Ubuntu Software, search for and install onboard as well as onboard settings.

Once installed, launch the utility from Gnome application menu.

In onboard settings, set up auto-show, layout, theme, etc and enjoy!

For Ubuntu 18.04 Gnome desktop, system and app notifications are shown also in the lock screen.

For some who want to hide these notifications on the lock screen, this quick tutorial will show you how.

1. First, open Ubuntu Software, search for and install dconf editor.

2. Once installed, launch dconf editor from application menu.

3. When it opens, navigate to org/gnome/desktop/notifications, and turn OFF the switch for “show-in-lock-screen”

That’s it. Enjoy!
