How To Fix Blurry Browsers with Fractional Scaling in Ubuntu 22.04

Ubuntu 12

In this article, we will be discussing how to fix blurry browsers with fractional scaling in Ubuntu 22.04. Fractional scaling is a feature that allows users to increase or decrease the size of on-screen content. However, it can sometimes cause blurriness in browsers like Google Chrome and Firefox. This issue seems to be specific to non-native applications. Let’s dive in and explore some potential solutions.

Quick Answer

To fix blurry browsers with fractional scaling in Ubuntu 22.04, you can try forcing Firefox to use Wayland by running the command MOZ_ENABLE_WAYLAND=1 firefox in the terminal. For Chromium, you can enable Wayland by running chromium --enable-features=UseOzonePlatform --ozone-platform=wayland in the terminal or by going to chromium://flags/#ozone-platform-hint in your browser. For other browser-based apps, the solution may vary. Additionally, you can enable Wayland in Ubuntu by editing the /etc/gdm3/custom.conf file.

Fixing Blurry Browsers in Firefox

Firefox is a popular browser used by many Ubuntu users. If you’re experiencing blurry content in Firefox, you can try forcing Firefox to use Wayland. Wayland is a protocol that specifies the communication between a display server and its clients. Here’s how to do it:

  1. Open the terminal. You can do this by pressing Ctrl + Alt + T.
  2. Enter the following command:
    MOZ_ENABLE_WAYLAND=1 firefox
    This command sets the MOZ_ENABLE_WAYLAND environment variable to 1 for the firefox application. This forces Firefox to use the Wayland display server instead of the default X11.

Fixing Blurry Browsers in Chromium

If you’re using Chromium (the open-source version of Google Chrome), you can enable Wayland by using the following steps:

  1. Open the terminal.
  2. Enter the following command:
    chromium --enable-features=UseOzonePlatform --ozone-platform=wayland
    This command enables the UseOzonePlatform feature and sets the ozone-platform to wayland for the chromium application.

Alternatively, you can go to chromium://flags/#ozone-platform-hint in your Chromium browser and choose Wayland.

Fixing Blurry Browsers in Other Browser-Based Apps

The solution for enabling Wayland in VSCode or other browser-based apps may vary. It is recommended to check the documentation or community support for the specific application.

Enabling Wayland in Ubuntu

If the issue is not specific to browsers, you can try enabling Wayland in Ubuntu by editing the /etc/gdm3/custom.conf file. Here’s how to do it:

  1. Open the terminal.
  2. Enter the following command:
    sudo nano /etc/gdm3/custom.conf
    This command opens the custom.conf file in the nano text editor with superuser permissions.
  3. In the editor, find the line #WaylandEnable=false and uncomment it by deleting the #. Then, set WaylandEnable=true and save the file. This enables Wayland in the GDM3 display manager.
  4. Reboot your device or restart GDM3 by running:
    sudo systemctl restart gdm3
    This command restarts the GDM3 service, applying the changes you made to the custom.conf file.

Other Considerations

It’s worth noting that some users have reported that uncommenting the #WaylandEnable=false line in /etc/gdm3/custom.conf alone solved the issue for them. However, this may not work for everyone. Remember to adjust the scaling factor and other settings according to your preferences. It’s recommended to experiment with different settings to find the optimal configuration for your display.

We hope this guide helps you in resolving the blurry browser issue with fractional scaling in Ubuntu 22.04. Happy browsing!

What is fractional scaling in Ubuntu 22.04?

Fractional scaling is a feature that allows users to increase or decrease the size of on-screen content in smaller increments than the traditional scaling options. It provides more precise control over the size of elements on the screen.

Why do browsers become blurry with fractional scaling?

The blurriness issue in browsers with fractional scaling is often specific to non-native applications. When the scaling factor is not an exact multiple of the display’s native resolution, the browser may not render the content as sharply, resulting in blurriness.

How can I fix blurry browsers in Firefox?

One potential solution is to force Firefox to use Wayland by setting the MOZ_ENABLE_WAYLAND environment variable to 1 for the firefox application. This can be done by running the command MOZ_ENABLE_WAYLAND=1 firefox in the terminal.

How can I fix blurry browsers in Chromium?

To fix blurry browsers in Chromium, you can enable Wayland by running the command chromium --enable-features=UseOzonePlatform --ozone-platform=wayland in the terminal. Alternatively, you can go to chromium://flags/#ozone-platform-hint in your Chromium browser and choose Wayland.

What should I do if the solution for enabling Wayland in VSCode or other browser-based apps is different?

If the solution for enabling Wayland in specific browser-based apps differs, it is recommended to consult the documentation or community support for that particular application. They may provide instructions or workarounds specific to their software.

How can I enable Wayland in Ubuntu?

To enable Wayland in Ubuntu, you can edit the /etc/gdm3/custom.conf file. Open the terminal and run sudo nano /etc/gdm3/custom.conf to open the file in the nano text editor. Then, uncomment the line #WaylandEnable=false by deleting the #, and set WaylandEnable=true. Save the file and restart GDM3 by running sudo systemctl restart gdm3.

What should I do if uncommenting the `#WaylandEnable=false` line in `/etc/gdm3/custom.conf` doesn’t solve the issue?

If uncommenting the #WaylandEnable=false line alone doesn’t solve the issue, you can try other troubleshooting steps. Adjusting the scaling factor and experimenting with different settings may help. It’s recommended to find the optimal configuration for your display by testing different options.

Are there any other considerations to keep in mind?

Yes, it’s important to remember that the optimal solution may vary depending on your specific hardware and software setup. Additionally, adjusting fractional scaling may impact the performance and visual quality of other applications. It’s recommended to test and find a balance that works best for your needs.
