Set Up Dual Monitors in Ubuntu Linux: A Step-by-Step Guide
Setting up dual monitors in Ubuntu Linux connects a second screen and adjusts its display settings.
This lets you expand your computer’s workspace across multiple screens, making it easier to get more done.
Recent versions of Ubuntu, like Ubuntu 22.04 LTS, handle multiple monitors well.
Usually, Ubuntu finds your second monitor right after you plug it in.
If Ubuntu doesn’t see the new screen, or if you want to change how they work together, you can use the Display settings.
In Display settings, you can make your desktop spread across both screens, show the same thing on both, or just use one screen.
Connect your external monitor, then open System Settings and select the Display panel. Drag the monitor icons to arrange them, choose “Join Displays” or “Mirror,” and click Apply. You can also set a primary display and adjust resolution or orientation.
How to set up additional monitors in Ubuntu Linux
Setting up dual monitors in Ubuntu Linux is achievable using the System Settings. This tool lets you connect and arrange your extra screens so they work together, making your workspace more efficient. You can choose how your monitors are positioned relative to each other and which one is primary.
Ubuntu Linux uses the System Settings panel as a central hub for managing most configurations. This panel handles everything from system settings and user creation to software updates.
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.
Click on the Display tile to open the panel in the Settings app.
The display arrangement diagram allows you to drag your monitors to set them up in the positions you want, creating a visual representation that matches your physical desk layout.
Then, select the display number you’d like to configure as primary or secondary. Feel free to drag the screens again to get the relative positions just right.
When using two screens, you have these display modes:
- Join Displays: screen edges are joined so things can pass from one Display to another.
- Mirror: the same content is shown on two displays with the same resolution and orientation.
- Single Display: only one Display is configured, effectively turning off the other.
With both monitors shown, you can select each monitor’s orientation, resolution or scale, and refresh rate if they need adjustments.
And that’s all there is to it! You can now close the Settings app.
Conclusion:
- Adding a second monitor to Ubuntu Linux is a simple process that enhances productivity.
- Ubuntu’s system settings provide a user-friendly interface for configuring multiple displays, offering options for display arrangement and modes such as Join Displays, Mirror, and Single Display.
- Users can effortlessly set the primary and secondary displays, adjust the orientation, resolution, scale, and refresh rate, and apply the changes with just a click.
- Enjoy the expanded workspace and improved multitasking capabilities with the seamless integration of additional monitors in Ubuntu Linux.
