How to enable Hot Corners on Ubuntu 18.04

Hot Corners can perform productive actions such as minimizing all open windows instantly, launch an application, or run a command.

Ubuntu unity users must be familiar with the Hot corners tool, using which one can easily set custom functions to perform when the mouse pointer is moved to the corner of the screen.

Hot corners can be set to each of all four corners of the screen to perform productive actions such as minimize all windows to show desktop, show apps grid, launch an application, or run a command too.

Starting with Ubuntu 17.04, Unity desktop environment got replaced with GNOME, and since then, the hot corners are gone missing. GNOME doesn’t have that feature.

Well, not exactly when you open the GNOME to the world of extensions. With GNOME extensions along with GNOME tweaks, you can get the hot corners back in Ubuntu.

Enabling Hot Corners in Ubuntu 17.04 and above

This guide is tested to be working on Ubuntu 18.04 LTS, but there should be no problem in applying it in Ubuntu 17.04 and Ubuntu 17.10 too.

1. Enable GNOME extensions

You need to install GNOME Shell extensions to be able to utilize the power of extensions. Head over to our step-by-step guide on how to install GNOME extensions and then continue to step next.

2. Install GNOME tweaks

GNOME tweaks help you in configuring the hot corners. Launch ‘Terminal’ and enter the following command to install it.

sudo apt install gnome-tweaks

3. Install Custom Corner GNOME extension

Go to the Custom Corner page and turn the slider to ON, and go ahead and click ‘Install’ when you see the dialog box.

Click “Extensions” and then click the settings icon in the “Custom Corner” section.


Use the drop-down list to set the hot corner actions. For example, in the below screenshot, I have set “Show Apps Grid” for the top right corner, “Show Desktop” to the bottom right, and “Show Overview” to the left bottom corner.

Whenever you hover the mouse to the corners, you should see the action! I love the “Show Desktop” action, which minimizes all the open windows and shows the desktop instantly!
