If you have recently installed Ubuntu 14.04 Trusty Tahr on Oracle VM VirtualBox Manager, you may notice that your screen isn’t re-sizing and you are unable to copy and paste into the terminal even after you had set both ‘Shared Clipboard’ and ‘Dran’n’Drop’ to Bidirectional. You need to install the VirtulaBox Guest Additions to resolve this. Below is recommended steps to accomplish that:
Install Steps
– Install DKMS (Dynamic Kernel Module Support) Package
– Mount Guest Additions CD Image…
– From terminal, run following commands. Note your username will be different from mine and also the Virtualbox version if not v4.3.10 r93012
– Reboot Machine
