Ubuntu – Resolution doesn’t change when resizing Virtualbox window


I've installed Ubuntu 64bit on Virtualbox 4.2.16. Guest Additions were installed in Ubuntu as well.

However the display resolution of Ubuntu does not seem to change as the Virtualbox window is resized or if we were to go into Full Screen mode. Any ideas?

  • Install the latest version of virtualbox say 4.3.10 or above from here and also it's corresponding guest additions, extensions Or you can also install the latest virtualbox version from the multiverse repository via apt-get. I also faced the same problem in older virtualbox version running Ubuntu 14.04 as guest OS.

    To install guest additions, follow this answer.
