How To Customize Monitor Scaling in Ubuntu 18.04

Ubuntu 21

In Ubuntu 18.04, the default display configuration provides two scaling options, 100% and 200%. However, if you need a custom display scaling, there are a few ways to achieve this. In this article, we will explore two methods: using the GNOME Tweak Tool and enabling fractional scaling in Wayland.

Quick Answer

To customize monitor scaling in Ubuntu 18.04, you can use either the GNOME Tweak Tool or enable fractional scaling in Wayland. The GNOME Tweak Tool provides a straightforward way to adjust the scaling, while Wayland offers more flexibility with fractional scaling. However, it’s important to note that Wayland’s fractional scaling is an experimental feature and may not be suitable for all use cases.

Using GNOME Tweak Tool

The GNOME Tweak Tool is a powerful tool that allows you to customize many aspects of your GNOME desktop, including the display scaling.

Installation

You can install the GNOME Tweak Tool by running the following command in a terminal:

sudo apt install gnome-tweak-tool

Here, sudo is used to run the command with root privileges, apt is the package handling utility in Ubuntu, install is the command to install a package, and gnome-tweak-tool is the name of the package to be installed.

Configuration

Once installed, you can open the GNOME Tweak Tool by running the command gnome-tweaks in the terminal. In the tool, navigate to the “Fonts” tab and look for the “Scaling Factor” setting. Here you can adjust the setting to your desired custom scaling, such as 1.25 for 125% scaling.

Using Wayland

Wayland is the display server protocol used in Ubuntu 17.10, but it’s not the default in 18.04. However, it does offer the ability to enable fractional scaling.

Enabling Fractional Scaling

To enable fractional scaling in Wayland, open a terminal and run the following command:

gsettings set org.gnome.mutter experimental-features "['scale-monitor-framebuffer']"

In this command, gsettings is a command line interface to GSettings, which is used to store application preferences. The set command is used to change a setting, org.gnome.mutter is the schema, experimental-features is the key, and ['scale-monitor-framebuffer'] is the value, which enables the experimental feature of fractional scaling.

Configuration

After enabling fractional scaling, navigate to Settings -> Devices -> Displays. You should now have the ability to scale in fractions, such as 100%, 125%, 150%, and so on.

Please note that enabling fractional scaling in Wayland is an experimental feature and may not work perfectly in all cases.

Conclusion

Customizing monitor scaling in Ubuntu 18.04 can be achieved using either the GNOME Tweak Tool or Wayland. While the GNOME Tweak Tool offers a straightforward way to adjust the scaling, Wayland offers more flexibility with fractional scaling. However, it’s important to note that Wayland’s fractional scaling is an experimental feature and may not be suitable for all use cases.
