Ubuntu 20.10: System Setup and Tweaking

This is part of my Ubuntu 20.10 Groovy Gorilla install. In the last post, I installed my essential applications. In this one, I’ll run through the tweaks and system setup that I did on my install.


To make AppImages work better, I installed the daemon:

cd ~/Downloads/
wget "https://github.com/AppImage/appimaged/releases/download/continuous/appimaged-x86_64.AppImage"
chmod a+x appimaged-x86_64.AppImage
./appimaged-x86_64.AppImage --install

Than, I also installed Flatpak to support those apps.

sudo apt install flatpak

Normally, I put the flatpak files in my ~/bin directory. It just picks them up from there and adds them to the menu.


Here are some of the utilities that I use to manage or tweak the system:

  • menulibre: I like to use this to add application launchers to my menu for programs that didn’t get added automatically
  • 7zip: for compressing and uncompressing files
  • synaptic: makes working with deb packages easier since I don’t have to remember the command-line syntax
  • Gnome Tweak Tool: has some additional settings to tweak in Gnome
sudo apt install menulibre \
      p7zip-full p7zip-rar \
      synaptic \

Settings Tweaks

On the regular settings App, I made the following changes:

  • Date & Time, changed the Time Format to AM/PM
  • Power, turned on Show Battery Percentage
  • Users, added a profile picture to my user

Then, I launched the Gnome Tweaks tool (just called “Tweaks” in the menu). I made the following changes there:

  • Top Bar: checked Weekday under Clock
  • Windows: unchecked Attach Modal Dialogs

Gnome Extensions

You can view Gnome Extensions from the Tweaks tool, but you can’t install them from there. Instead, you have to have a Chrome extension to install and manage from the browser. You can install the extension from the Chrome Store.

Then, you need the following package to make it work:

sudo apt install chrome-gnome-shell

Then, these are the extentions I installed:
