How to Modify Screen Resolution on Ubuntu?

Setting the screen resolution in Ubuntu is not a difficult job. So, let’s have a look at how to change screen resolution in Ubuntu in short.

You may have observed that the Ubuntu machine’s resolution is smaller than your system’s screen size. There are mainly two ways to change resolution in Ubuntu One using Graphical User Interface and another using the terminal. So, Let’s discuss how to change the resolution using Graphical User Interface.

With Graphical User Interface

Step 1: In a low-resolution Ubuntu desktop, the icons are huge. They do not seem as clear as we would want. You’ll learn how to modify it according to your preferences in the following step.

Step 2: Use the search option at the top of the launcher menu to search for “display.” Then you’ll notice “Displays.” Just click on this to open it.

Step 3: In the “Displays” section, you can find the “Resolution.” You can select any resolution from the given list according to your preferences.

Step 4: Click on “Apply” to apply the selected resolution.

Step 5: You may notice that the resolution changes in the background once you click on it. A dialogue box may pop up in the meanwhile, saying, “Does this display look OK?”. Now, you have to decide if the selected resolution fits your preferences. If so, select “Keep This Configuration”; otherwise, click “Restore Previous Configuration” and make changes until you are satisfied with the resolution.

Step 6: When you’re done making adjustments, click “Apply” to save the changes you’ve made to your system’s resolution.

With the Terminal

Step 1: To modify your Ubuntu system’s current resolution, you must first choose which resolution is appropriate for your system. Check if the resolution you’re about to set is listed among the options. To do this, enter “xrandr.”

Step 2: As a result, you will find the present resolution of your desktop along with a list of resolutions. You can choose any resolution you want after selecting the desired resolution type “xrandr -s 1280×1024” and press enter.

Step 3: Here, we have used xrandr, which allows you to change the screen resolution, orientation, and refresh rate. And the “-s” before the resolution size tells the terminal to modify the screen size. It can be used by giving the size index, i.e., the ratio, or mentioning the <width> x <height>.

Step 4: As a result, you can see that the resolution has been changed as per your preferences.


So it was brief on the ways to modify screen resolution. We have included all possible methods to modify screen resolution on Ubuntu. However, if you have something different, then please let us know.
