Gnome Bedtime – Enable “Android’s Bedtime Mode” for Linux

For Gnome users, you can now get “Android’s bedtime mode” style interface via Gnome Shell Extension.

Gnome Bedtime is a simple tool to convert your desktop workspace to grayscale. Similar to Android’s bedtime mode which converts the phone screen to grayscale, it should somewhat make your device less appealing and limit the usage of it before bedtime.

How to Install Gnome Bedtime:

1. For Ubuntu based systems, firstly open terminal and run command to install the required library.

sudo apt install chrome-gnome-shell

2. Then go to this web page and turn on the toggle icon to install the Gnome Shell Extension.

Don’t see the toggle icon? Click the link which says “click here to install browser extension“. Then refresh the web page after installed the browser extension.

Toggle on / off Gnome Bedtime:

Either Gnome Tweaks or Extensions has option to toggle on or off the Gnome Shell Extension.

To install Gnome Tweaks, run the command in terminal for Ubuntu based systems:

sudo apt install gnome-tweaks

And run this command instead in Fedora based systems:

sudo yum install gnome-tweaks

To install the Extensions tool, run command in terminal for Ubuntu based systems:

sudo apt install gnome-shell-extension-prefs

And run this command instead in Fedora based systems:

sudo yum install gnome-extensions-app

Alternatively, you can enable/disable the extension from command line:

gnome-extensions enable [email protected]
gnome-extensions disable [email protected]

So you can schedule it nicely with crontab, your own scripts or some other extensions (e.g., Night Theme Switcher) that support scheduling.
