Enable Fractional Scaling in Ubuntu: A Step-by-Step Guide

This article describes steps to turn on or off fractional scaling in Ubuntu Linux.

By default, Ubuntu Linux comes with two scaling options: 100% and 200%. Most devices, including those with 4k or HiDPI support, may work with the default scaling options.

However, if your device’s display resolution makes objects and icons too small at 100% or too big at 200%, you may want to enable fractional scaling.

Fractional scaling support is not automatic, and it’s disabled by default. If you want to use it, you must enable it.

Below is how to turn fractional scaling on or off in Ubuntu Linux.

How to turn on or off fractional scaling in Ubuntu Linux

As described above, by default, Ubuntu Linux comes with two scaling options: 100% and 200%. Most devices, including those with 4k or HiDPI, may work with the default scaling options.

Below is how to enable it.

Ubuntu Linux has a centralized location for the majority of its settings. From system configurations to creating new users and updating, all can be done from the System Settings panel.

To get to System Settings, open the Activities overview and start typing Settings.

Alternatively, click on the System menu at the top-right corner of the top bar on your desktop.

On the System menu, select Settings, as highlighted below.

In the Settings app, click on the Displays tile.

On the System Settings -> Displays settings panel, under Built-in or external monitor, toggle the switch button for Fractional Scaling to On position to enable it.

To disable, toggle back to the Off position.

With Fractional scaling enabled, you get additional scaling values: 125%, 150%, and 175%.

That should do it! You can now close the Settings app.

Conclusion:

• Fractional scaling in Ubuntu Linux allows for more precise control over the display scaling options, particularly beneficial for devices with high-resolution displays.
• Enabling fractional scaling provides additional scaling values such as 125%, 150%, and 175%, offering more flexibility in customizing the display size.
• The System Settings panel in Ubuntu Linux provides a straightforward method for toggling fractional scaling on or off, catering to individual preferences and display requirements.
• This enhanced scaling functionality enhances the overall user experience on Ubuntu, ensuring a more tailored and visually optimized display.
