How To Setup Another Monitor with Ubuntu VM in Virtualbox

Ubuntu 10

In this article, we’ll be walking through the steps on how to set up an additional monitor with an Ubuntu Virtual Machine (VM) in VirtualBox. This can be particularly useful when you’re working on multiple tasks simultaneously and need more screen space.

Quick Answer

To set up another monitor with an Ubuntu VM in VirtualBox, you need to adjust the VM settings by increasing the video memory and setting the monitor count to 2. Then, start the VM and configure the display settings in Ubuntu to add and configure the additional monitor. If you encounter any issues, refer to the troubleshooting section for possible solutions.

Prerequisites

Before we begin, make sure you have the following:

  • A working installation of VirtualBox.
  • An Ubuntu VM set up in VirtualBox.
  • An additional monitor connected to your computer.

Step 1: Shutdown the Virtual Machine

The first step is to shut down your Ubuntu VM. This is necessary because changes to the display settings cannot be made while the VM is running. To do this, select the VM in VirtualBox and click on the “Close” button.

Step 2: Adjusting the VM Settings

Once the VM is shut down, right-click on it and select “Settings”. This will open up a new window where you can adjust various settings for the VM.

Display Settings

Navigate to the “Display” tab in the settings window. Here, you’ll find options to adjust the video memory and monitor count.

Video Memory: Increase the video memory to a value higher than 64MB. This is necessary to ensure that your VM has enough resources to handle the additional monitor.

Monitor Count: Set the monitor count to 2. This tells VirtualBox that you want to use two monitors with your VM.

Step 3: Starting the VM and Configuring Ubuntu Display Settings

After adjusting the settings, start your VM and open the Ubuntu guest. Once it’s up and running, navigate to the system settings and then to the display settings. Here, you should see an option to add another monitor. Configure the display resolution for the additional monitor as per your preference.

Troubleshooting

If you’re not able to see the option to add another monitor or if you’re facing issues with a black screen, there are a few things you can try:

Change the Graphics Controller: In the VirtualBox settings under the “Display” tab, try changing the graphics controller from “VMSVGA” to “VBoxVGA” or vice versa.

Adjust Video Memory Allocation: If you’re still facing issues, try increasing the video memory allocation. You can set it to a value as high as 128MB.

Disable 3D Acceleration: If you’ve enabled 3D acceleration in the display settings, try disabling it to see if that resolves the issue.

Enable Second Monitor through VirtualBox Interface: If none of the above solutions work, try enabling the second monitor through the VirtualBox interface itself. You can do this by switching the VM to floating window mode and clicking on the monitor icon in the lower bar of the VM window. From there, you can enable the second monitor.

Conclusion

Setting up an additional monitor with an Ubuntu VM in VirtualBox can greatly enhance your productivity by providing more screen space. While the process can be a bit tricky, following the steps outlined in this article should help you get it set up without much hassle. If you encounter any issues, don’t hesitate to refer to the troubleshooting section or seek help from the VirtualBox forums.
