How to Change Resolution on Kali Linux VirtualBox

When setting up a virtual machine using VirtualBox and Kali Linux, users may encounter issues with screen resolution. In this article, we will explore how to change the resolution on Kali Linux VirtualBox.

To begin with, it's essential to understand that the monitor settings need to be mirrored in order for the changes to take effect. This was a crucial step in my own trial and error process when I was struggling with the same issue.

The first thing you should do is check your monitor settings. Make sure that your monitor is set as the primary screen. In my case, my monitor was a low-to-mid range gaming monitor, and it had a much higher native aspect ratio and resolution than my laptop's integrated screen.

To resolve this issue, I used the RealVNC dummy driver, which can be found on the official RealVNC website. The configuration file used by SystemXorg is located in the /etc/X11/nf file.

To install the RealVNC dummy driver, you will need to compile it on the computer running RealVNC Server using the following commands:

* `sudo apt install git` (for Ubuntu users)

* Compile and install the RealVNC dummy driver

Alternatively, you can use the Dynamic Resolution feature available in RealVNC Viewer 7.6.0 and later versions. This feature allows you to dynamically define desktop resolutions in configuration files or at the command line.

Another option is to run a Virtual Mode session with a large desktop resolution, such as 4K (3840x2160) that has a pixel clock higher than 300MHz. However, it's recommended to compile and install the RealVNC dummy driver if you need to use these high-resolution settings.

For users running SystemXorg, you can specify non-standard screen resolutions by adding additional ModeLine entries to the Monitor section of the /etc/X11/nf file. This allows a connected RealVNC Viewer user to choose from multiple screen resolutions and cycle between them using the command line utility xrandr or the virtual desktop's Display/Monitor settings app.

In conclusion, changing resolution on Kali Linux VirtualBox can be achieved by using the RealVNC dummy driver, Dynamic Resolution feature, or running a Virtual Mode session. By following these steps, you should be able to resolve any issues with screen resolution and enjoy a smoother virtual desktop experience.
