VirtualBox is a powerful and versatile virtualization software, but like any complex tool, it can sometimes behave erratically. One common issue that users encounter when running Ubuntu as a guest operating system in VirtualBox is mouse-related problems. This article provides a detailed guide on how to troubleshoot and fix these issues.
To fix VirtualBox mouse issues in Ubuntu, you can try killing the VirtualBox drag&drop processes, changing VirtualBox settings, switching from Wayland to XOrg, or using a script available on GitHub. These solutions should help resolve most mouse-related problems in VirtualBox.
Understanding the Issue
The mouse issue in Ubuntu on VirtualBox can manifest in several ways. You might find that the mouse pointer is not visible, or the mouse click is not working inside windows but working outside. Sometimes, the mouse may work fine in windowed mode but cause problems in full-screen mode. Understanding the specific issue you’re facing is the first step towards troubleshooting it.
Solution 1: Killing the VirtualBox Drag&Drop Processes
One of the most common solutions to fix the mouse issue in Ubuntu on VirtualBox is to kill the VirtualBox drag&drop processes. Here’s how you can do it:
- Open a terminal in Ubuntu.
- Type the command
ps -ax | grep VBoxClientand press Enter. This command lists all the processes related to VirtualBox. The
ps -axcommand shows all the running processes, and
grep VBoxClientfilters out the processes that contain the text
- Look for the processes that contain the text
- To kill these processes, use the
killcommand followed by the process ID. For example, if the process ID is 1234, you would type
kill 1234and press Enter.
Solution 2: Changing VirtualBox Settings
Another solution is to tweak the settings in VirtualBox. Here are a few things you can try:
- Disable Drag and Drop: In the VirtualBox Manager, select your Ubuntu virtual machine and click on Settings. Under the General tab, go to the Advanced tab and set Drag’n’Drop to Disabled.
- Turn Off Mini Toolbar in Fullscreen Mode: If your mouse issue occurs in fullscreen mode, try turning off the mini toolbar. You can find this setting under the User Interface section of the Display settings.
- Disable Auto Capture Keyboard: This setting can be found in the Input settings of VirtualBox Manager. Uncheck the box that says “Auto Capture Keyboard”.
- Change Graphics Controller to VMSVGA: In the Display settings, change the Graphics Controller to VMSVGA.
Solution 3: Switching from Wayland to XOrg
Ubuntu 17.10 and later versions use Wayland as the default display server, but VirtualBox works better with the older XOrg server. To switch to XOrg, log out of Ubuntu, click on the gear icon on the login screen, and select “Ubuntu on Xorg”.
Solution 4: Using a Script to Fix the Issue
If none of the above solutions work, you can try using a script available on GitHub that can potentially fix the issue. You can find the script at this link.
While the mouse issue in Ubuntu on VirtualBox can be frustrating, it’s usually not too difficult to fix. The solutions outlined above should help you get your mouse working properly again. If you’re still having trouble, consider reaching out to the VirtualBox community or Ubuntu forums for further assistance. Remember, the key to successful troubleshooting is patience and a systematic approach. Good luck!
