VirtualBox guest additions

Higher screen resolution in VirtualBox?

  1. Start Virtual box and log into Ubuntu.
  2. Hit the right ctrl key so you can get your mouse pointer outside the virtual machine.

3.Go to top of virtual window, click on devices then select “Install Guest Additions” You will see a window pop up inside Ubuntu showing you that there are some new files mounted in a virtual CDROM drive. One of those files should be VBoxLinuxAdditions.run

You must run the file with some admin permissions so do that this way…

  1. Click inside the Ubuntu screen again then go to Applications – Accessories then Terminal. The terminal window is where you will run the file from, but first we must navigate to the correct directory.
  2. type this… cd /media/cdrom0 (then hit enter, there is a space after cd!)
  3. next type… dir (You should see amongst the files displayed VBoxLinuxAdditions.run)
  4. now type… sudo sh ./VBoxLinuxAdditions.run (yes, that is a full stop before the slash!)

after you hit enter and it has done its stuff, the files are now accessable from Ubuntu.

  1. You now need to reboot the virtual machine or press Ctrl+Alt+backspace.
