How to Change Resolution Ubuntu Virtual Machine

Are you struggling to change the resolution on your Ubuntu virtual machine? Are blurry or pixelated images getting in the way of your work or play?

In this blog post, we will guide you through easy and quick steps to adjust and improve the screen resolution within your virtual environment. Let’s get started!

How to Change Resolution Ubuntu Virtual Machine

Introduction to Ubuntu Virtual Machines

If you are using Ubuntu as your host operating system and need to change the resolution of your Ubuntu virtual machine, here are the steps you need to follow.

  1. Start by closing any applications that are currently running in your Ubuntu virtual machine.
  2. Next, open the “System Settings” window by clicking on the “System” menu item in the top panel and then selecting “System Settings.”
  3. In the System Settings window, click on the “Displays” icon.
  4. In the Displays window, make sure that the correct display is selected from the drop-down list at the top of the window (this will likely be “Default”).
  5. Below this, you will see a slider labeled “Resolution.” Drag this slider to change the resolution of your Ubuntu virtual machine’s display.
  6. Finally, click on the “Apply” button to apply your changes.

Understanding Resolution & Aspect Ratios

  1. Resolution refers to the number of pixels that make up an image, and is usually represented by width x height (e.g. 1920×1080). Aspect ratio is the ratio of an image’s width to its height (e.g. 16:9 or 4:3).
  2. Ubuntu’s default resolution is 1024×768, but this can be changed to better fit your monitor or projector. To do this, open System Settings from the Dash, select “Displays”, and then change the “Resolution” drop-down to the desired setting.
  3. Aspect ratio is something that is often overlooked, but it can have a big impact on how an image looks. For example, most monitors have a 16:9 aspect ratio, while most projectors have a 4:3 aspect ratio. If you try to view a 16:9 image on a 4:3 projector, it will appear stretched out and distorted. Conversely, if you try to view a 4:3 image on a 16:9 monitor, it will appear with black bars on the sides.
  4. To change the aspect ratio of an image in Ubuntu, open the Image Viewer application and go to File > Properties. In the “Image Properties” window that appears, click on the “Advanced tab” and then change the “Aspect Ratio” drop-down to the desired setting.

Identifying Your Machine’s Current Resolution

If you’re not sure what your machine’s current resolution is, there are a few ways to find out. The first way is to open the System Settings window, click on the “Displays” icon, and then look at the Resolution drop-down menu.

The second way is to use the xrandr command in a terminal window. To do this, open a terminal window and type “xrandr” (without the quotes). This will give you a list of all the available resolutions for your monitor.

Choose the one that you want to use and then type “xrandr –output –mode “ (without the quotes), where is the name of your monitor and is the resolution that you want to use.

Adjusting the Screen Resolution of a Virtual Machine

It is possible to change the screen resolution of a virtual machine by changing the display settings in Ubuntu.

To do this, open the System Settings window by clicking on the cog icon in the top right corner of the screen.

In the System Settings window, click on “Displays” to open the Displays settings.

In the Displays settings, you can change the resolution of your display by dragging the slider under “Resolution.”

Applying Changes and Troubleshooting Tips

If you have made changes to your Ubuntu Virtual Machine that you want to keep, there are a few ways to apply those changes and make sure they persist through a reboot.

One way is to use the command line tool “screen” with the “-S” option. This will save your current session and give it a name.

You can then use the “screen -r” option to resume that session, which will have all of your changes from earlier.

Another way is to use the “vncserver” command, which will allow you to view and control your Ubuntu VM from another computer.

This is useful if you want to make changes from a distance or share your desktop with others.

If you are having trouble applying changes or troubleshooting your Ubuntu VM, there are a few tips and tricks that can help.

  1. First, check the logs for any error messages that might be helpful in troubleshooting the issue.
  2. Second, try using a different user account if you have one set up. If the problem persists, try reboot the machine and see if that helps.
  3. Finally, try resetting any changed settings back to their defaults and see if that resolves the issue.


As you can see, it’s quite easy to change the resolution of an Ubuntu virtual machine. The important thing is to remember which commands and configurations are needed in order to properly adjust your settings.

Once you have everything set up correctly, you should be able to run a virtual machine with no issues or hiccups due to resolution incompatibilities.

With this information at your disposal, hopefully changing the resolution of a virtual machine will never present any difficulties for you again!
