[Quick Fix] Touchpad Right-click not working in Ubuntu 18.04

Last updated: July 15, 2018

gnome shell

After doing a fresh install of Ubuntu 18.04 on my old ASUS laptop, I found that the touchpad right-click does not work. This is because Ubuntu 18.04 by default acts right-click when you perform two-finger click on touchpad.

While my laptop touchpad does not have physical buttons, I have to do two-finger click to perform right-click.

So following steps will show you how to make right-click (clicking on the bottom right area of the touchpad) working again in touchpad without a physical button in Ubuntu 18.04.

1. Open Ubuntu Software, search for and install Gnome Tweaks.

2. Launch Gnome Tweaks and navigate to Keyboard & Mouse settings page.

Under Mouse Click Emulation, simply click enable the second option: “Area – Click the bottom right of the touchpad for right-click and the bottom middle for middle click.”

That’s it. Enjoy!

Install Latest GNU Octave in Ubuntu 24.04 | 22.04 | 20.04

Last updated: April 26, 2024

This quick tutorial shows you how to install the latest GNU Octave in all current Ubuntu releases via Flatpak packages.

Since there’s no stable PPA contains the latest Octave packages, Flatpak package is the easiest way to get the numerical computation software running on Ubuntu.

Similar to Snap, Flatpak is an universal Linux package format that runs in sandbox.

1. First open terminal (Ctrl+Alt+T) and make sure Flatpak support is enabled by running command:

sudo apt-get install flatpak

Old Ubuntu 16.04 & Ubuntu 18.04 need to add the Flatpak PPA first to install Flatpak framework.

sudo add-apt-repository ppa:flatpak/stable

2. Then add the Flathub repository, the best place to get Flatpak apps:

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

3. Finally install most recent GNU Octave as Flatpak package from the Flathub repository:

flatpak install flathub org.octave.Octave

It will take a few minutes downloading the flatpak package as well as dependency platform if you’re first time installing it.

Like normal applications, you can launch Octave from Gnome app launcher:

The flatpak co-exists with traditional Octave package. You can alternatively run it in command line:

flatpak run org.octave.Octave

Uninstall

You can remove the Octave flatpak package by running command:

flatpak uninstall --delete-data org.octave.Octave

And remove flatpak support if you want:

sudo apt-get remove flatpak
