Ah! taking screenshots in VirtualBox should be easy shouldn’t it? It sounds like such a trivial task: just press the PrtSc button and bam! You’ve got your screenshot.
But what do you do when that simply button just doesn’t work the way you expected?
In this quick guide I’m going to show you how to take a screenshot in VirtualBox. We are using Ubuntu 16 as our Guest VM.
Let’s jump in shall well!?
The easiest way to take a screenshot is to simply press the Print Screen button but what happens if you pressing that button simply doesn’t work for you?
Let’s start with my Ubuntu 16 desktop
How to take a Screenshot in VirtualBox
When you press print screen button the screen should temporarily turn black while the gnome-screenshot dialog box loads.
Then you click Save and all is well.
How to fix the screenshot problem in VirtualBox
There are really just two things you need to check if your screenshots aren’t working. One of these two tricks will fix your problem.
1 Update VirtualBox and your Guest OS
2 Disable Compiz
Compiz is the Ubuntu application that makes the environment sing. You can use it to do all kinds of crazy things such as making your windows look like water or torching your desktop with fantastic flames. I won’t go into that here because it’s beyond the scope of the article but if you’re trying to solve your screenshot woes try disabling Compiz.
Assuming the Metacity windows manager is installed on your system, you can type:
metacity --replace &
If that doesn’t work you can easily see which media manager you have installed by running:
sudo apt-get install wmctrl
And then running:
So you can see I have Compiz enabled not MetaCity thus this command won’t work:
metacity --replace &
So here’s the trick: press Ctrl + Alt + t to pop open the terminal (don’t you just love keyboard shortcuts they make you feel so leet! hahaha)
And then get the CompizConfig Settings Manager (compizconfig-settings-manager)
sudo apt-get install compizconfig-settings-manager -y
We want to go to the Effects and Accessibility panes in the main window and disable any relevant settings there. Be careful how you use this tool though because you can cause damage to the OS if you’re not paying attention to what you’re clicking. For example, it’s possible to completely render your Ubuntu unusable if you mindlessly start disabling items.
