How To Fix “Low-Graphics Mode” Error in Virtualbox

Ubuntu 10

If you are a VirtualBox user, you may have encountered the “Low-Graphics Mode” error. This error typically occurs when the system has trouble loading the graphics drivers or when the system is running low on resources. In this article, we will guide you through several methods to fix this issue.

Update and Upgrade the System

The first step in troubleshooting this error is to ensure your system is up-to-date. You can update and upgrade your system by running the following commands in the terminal:

sudo apt-get update
sudo apt-get upgrade

The sudo command gives you administrative privileges, apt-get is the package handling utility in Ubuntu, update is used to resynchronize the package index files from their sources, and upgrade is used to install the newest versions of all packages currently installed on the system.

Install VirtualBox Guest Additions

VirtualBox Guest Additions are software packages that can be installed inside a guest virtual machine to improve its performance and usability. If you are encountering the low-graphics mode error, installing these additions may help. To install VirtualBox Guest Additions, follow the instructions provided by VirtualBox here.

Check for Available Disk Space

If your virtual hard drive is running low on space, it can cause the low-graphics mode error. You can free up disk space by removing unnecessary packages. Run the following commands:

sudo apt-get autoremove
sudo apt-get autoclean

The autoremove command removes packages that were automatically installed to satisfy dependencies for other packages and are now no longer needed. The autoclean command clears out the local repository of retrieved package files that can no longer be downloaded.

Install Graphics Drivers

In some cases, installing the appropriate graphics drivers can resolve the error. If you are using a host machine with an ATI graphics card, you can try installing the fglrx driver with the following commands:

sudo apt-get install fglrx
sudo reboot

The install command is used to install new packages, fglrx is the proprietary Linux driver for ATI graphics cards, and reboot is used to reboot the system.

Check and Fix /etc/environment File

If you have accidentally edited the /etc/environment file, it may cause the low-graphics mode error. You can check for any illegal entries in the file by logging in with sudo command permission and using a text editor like nano.

sudo nano /etc/environment

The nano command opens the nano text editor, and /etc/environment is the system-wide environment file.

In conclusion, the “Low-Graphics Mode” error in VirtualBox can be fixed by updating and upgrading the system, installing VirtualBox Guest Additions, checking for available disk space, installing graphics drivers, or checking and fixing the /etc/environment file. Remember to always back up your data before making any major changes to your system.
