Enable ‘2×2’, ‘3×3’ Workspace Grid in Ubuntu 18.04/19.10

Last updated: December 11, 2019

This is another tutorial about how to arrange workspaces in a two dimensional grid (2×2, 2×3, 3×3, etc.) in Ubuntu 18.04 and higher.

The Workspace Grid gnome shell extension does the job, it is however seems to be not maintained anymore.

The Workspace Matrix extension takes up the job and so far supports for Gnome Shell up to version 3.34.

With the extension, you can bring up the workspace grid via Super+W (press again to hide) key, and use arrow keys to navigate between workspaces.

1. First open Gnome Tweaks (install it via Ubuntu Software), and enable “Static Workspaces” under Workspaces tab.

2. Then install the Workspace Matrix extension in Ubuntu Software.

3. Launch the extension settings page either in Ubuntu Software (package installing page) or via Gnome Tweaks -> Extensions.

Finally set the number of rows, columns, and scale of workspace thumbnails.

That’s it. Enjoy!

Disable Installing Updates During Shutdown in Ubuntu 19.10

Last updated: December 10, 2019

While shutting down, Ubuntu sometimes gets stuck at purple screen with Ubuntu logo and the scrolling 5 dots. And it says ‘Unattended-upgrade in progress during shutdown, please don’t turn off the computer‘.

This happens not very often, and it’s OK to press and hold the power button to force shutdown Ubuntu, which will not break you machine.

You can also prevent Ubuntu from installing updates while shutting down simply by doing following steps one by one.

1.) Open applications menu, search for and launch Software & Updates utility.

2.) When it opens, navigate to Updates tab. Then disable ‘Automatically check for updates‘ by setting its value to Never.

That’s it.

NOTE: Disabling automatic updates comes with a security risk. You may launch Software Updater or run sudo apt update && sudo apt upgrade command to keep your system updated manually.

Restore Missing Dual / Triple Boot Menu in Ubuntu 18.04

Last updated: December 9, 2019

After installing recent updates in my Ubuntu 18.04 via Software Updater, Grub2 boot-loader menu is not showing on startup. The dual-boot (or triple-boot) operating system is no longer available when you press Shift (or Esc) to show the menu entry.

It seems to be a grub2 package issue in the recent update, though I’m not sure. And sudo update-grub can’t detect operating systems outside the current Ubuntu release.

If you happened to have the similar issue, try following steps to fix the problem.

1.) Open terminal and run following commands one by one to install grub-customizer:

sudo add-apt-repository ppa:danielrichter2007/grub-customizer

sudo apt update

sudo apt install grub-customizer

For Ubuntu 19.04 and higher, grub-customizer can be easily installed from Ubuntu Software.

2.) Launch Grub Customizer. When it opens, do:

  1. navigate to General Settings tab.
  2. check the first two check-boxes under visibility to show menu, check for other OSes.
  3. click on the Save button.

3.) After saving the changes, navigate to ‘List configuration‘ tab, and click on Refresh button.

The Grub2 boot-loader should finally list all available operating systems menu entries in the next startup.

Install Atom Text Editor via Apt Repository in Ubuntu 18.04 / Higher

Last updated: December 8, 2019

This simple tutorial shows how to install Atom text editor and receive future software updates via its official apt repository in Ubuntu 18.04 and higher.

Atom is a hackable text editor for the 21st century. It is available in Ubuntu Software via Snap package, which runs in sandbox and auto-updates itself once a new release is published.

However, for those prefer Ubuntu .deb package atom can be also installed and easily updated via its official apt repository.

1. Open terminal either from application launcher or by pressing Ctrl+Alt+T on keyboard. When it opens, run command to install the repository key:

wget -qO - https://packagecloud.io/AtomEditor/atom/gpgkey | sudo apt-key add -

Type user password (no asterisk feedback) when it asks and hit Enter.

2. Then run command to add the official Atom repository:

sudo sh -c 'echo "deb [arch=amd64] https://packagecloud.io/AtomEditor/atom/any/ any main" > /etc/apt/sources.list.d/atom.list'

3. Now you can always update an old Atom .deb software installation via Software Updater utility:

or run command in terminal to install (or upgrade) the editor:

sudo apt update && sudo apt install atom

replace atom with atom-beta in the code if you want to install the latest beta package.

Uninstall:

To remove the apt repository, open Software & Updates and navigate to Other Software tab, then remove the line says Atom Editor.

And remove the text editor if you want via command:

sudo apt remove atom atom-beta
