I tried many ways to make a bigger screen in VirtualBox because I do not like the small size of the guest window? Is there is a way to make it big?
You need to install the Guest Additions go to devices menu > select "install guest additions" after installation restart virtual system now select view menu and click "switch to full screen"
I tried the solution provided by Mawhrin-Skel. However, it didn't work for me the first time. Then I installed
virtualbox-guest-dkms and tried the solution again. This time it worked for me. Following are the steps that I followed
- Click Devices -> Insert Guest Additions CD image from the menu of the VM window
- Restart the VM
sudo apt-get install virtualbox-dkms sudo apt-get install virtualbox-guest-dkms sudo apt-get remove libcheese-gtk23 sudo apt-get install xserver-xorg-core sudo apt-get install virtualbox-guest-x11
Hope this helps
You need to enable "Scaled Mode" after installing Guest addons. Host+C
This is not a problem with Guest Additions not installing. If copy-and-paste works between your host and your VM that means Gues Additions installed ok.
Turn off your VM. On VirtualBox VM console, select the virtual machine, go to Settings->Display and set your Graphics Controller to VMSVGA. This will fix the problem.
Another problem is the Linux desktop will be fine until you do a "yum update". Some package is being updated and once it does, the desktop icons will become huge. Have not figured out what's causing this.
You should run the following commands in a terminal on your host Ubuntu session:
sudo apt-get remove libcheese-gtk23 sudo apt-get install xserver-xorg-core sudo apt-get install virtualbox-guest-x11
Once you have installed Windows Operating system go to the resolution settings by >Right Click > Screen Resolution > change to (1920 x 1080)
If this does not work keep trying each resolution within the Settings. You should come across one which will fit your screen.
Don't forget to also (Auto Fit Guest) within the Virtual Machine View Settings.
Devices --> Click on Insert Guest additions CD image option
If you have installed Ubuntu via Virtual Box on MacOS and experiencing an issue while trying to make the window size full screen, the solution is as follows.
Once Ubuntu has been installed, go to the the Virtual Box Menu Bar Devices -> Click on Insert Guest additions CD image option
Now, within Ubuntu you will be asked to provide sudo password and it builds the Virtual Box Guest Additions kernel module.
After restarting the VM , click on View -> Full Screen size and that should modify your display.
None of the above methods worked for me, but the easiest method that eventually worked for me (a Mac user) was:
- In the top menu, select View
- Select Virtual Screen 1
- Pick one of the options till one of them works for you (for me, it's Scale to 150% and anything percentage bigger than that)
I hope this helps!
if using virtual box to use ubuntu on any other host.
- Start the virtual machine, when ubuntu is booting up switch of virtual machine immediately.
- Start the machine again, and when ubuntu prompts some boot up options, select the first one...
- Your Ubuntu will start with a bigger screen size in comparison to the older one.
I was also very confused on this at first, but I figured out how.
This tutorial will work for most OS'es
First, you need to click on "Devices" on the bar at the top.
A pop down window will appear, so now you need to click "Insert Guest Additions" or something like that.
If you're using Windows XP or around that OS, then it will automatically pop up and start installing.
However, it will not happen on Windows 7 - 10. Therefore, we need to do something else.
Click on File Explorer, or search up in search "File Explorer", and it should look like a file inside a cabinet.
If you are on Ubuntu or other Linux, just search up "Files", and it should be one of the main results.
The photo of the File Explorer icon will be shown below.
Now, in the left side, there is a bar which shows "Quick Access", "This PC", and maybe some others.
It looks like this.
Now look next to the tab called "This PC", and there will be a small arrow on the left side of it. Press that, and you will see folders such as "Desktop", "Documents", and many more.
At the bottom, it should say something like "DVD Drive (E:) VirtualBox Guest Additions."
Click on it, and there will be many files. You have to double-click the file called VBoxWindowsAdditions.exe (If you are on Windows). On Linux, it will be similar, but don't select any of the AMD64 or x86 ones.
The file that you have to press will be shown in this image.
Go throught the steps, allowing all of it when it asks, and when it is done, click "I want to reboot now", and when you go back in, wait a few seconds, and it should automatically resize to fit the whole screen. Then you can press Right Ctrl + F (unless you changed the host key), and it will be almost perfect.
...Except for that little sliver on the bottom. It must go away, or our almost perfect virtual machine won't have that nice feel to it.
Close the virtual machine (completely close, not just save state), and right click the virtual machine you are doing this on. Choose "Settings", and go to the "User Interface" tab at the bottom.
There will be a checkmark that says "Show bar in fullscreen mode" or something like that, and it is checked by default. Uncheck it, apply the changes, and open the virtual machine.
Ta-da! The virtual machine does not look like a virtual machine anymore. It looks like your actual computer.
Now to get out of the fullscreen virtual machine, press the host button + F. The host button by default will be the right Ctrl key on your keyboard (Unless you changed it).
Now you know how to get to fullscreen without any distractions from your experience.

The size of your screen in the virtualbox is actually the problem of the guest OS not of virtualbox itself. You'll want to change the aspect ratio in the guest OS. In Ubuntu this can be done by clicking the downward facing arrow in the top right corner of the screen, this will open a small window in that area, click on the settings button, then go down to devices, and then display, and select a display size. The correct choice will depend on your monitor, but I selected "1440X900(16:10)" and that got rid of the gray borders on my computer.
