Paper GTK3 and Icon themes

This is a beginner’s guide shows how to remove the ‘Show Applications’ app menu icon from the dock in Ubuntu 20.04, Ubuntu 20.10.

Why to remove the icon:

The default ‘Show Applications’ app launcher is always a bit slow when I clicking on the 9 dots icon on left dock to show the app menu, even after disabled animation and changed privacy settings.

And I only use it to search for and open applications, which can be done alternatively via the top-left Activities button.

In brief, it’s slow and I use Activities button to search for and open applications.

How to Remove it:

If you’re familiar with Linux command, press Ctrl+Alt+T on keyboard to open terminal and run command:

gsettings set org.gnome.shell.extensions.dash-to-dock show-show-apps-button false

That’s it.

You can alternatively open Dconf Editor (install via Ubuntu Software if you don’t have it) and navigate to “org/gnome/shell/extensions/dash-to-dock”.

Then turn off the toggle for the key ‘show-show-apps-button’.

(Optional) To restore the change, either use Dconf Editor or run command:

gsettings reset org.gnome.shell.extensions.dash-to-dock show-show-apps-button
