VirtualBox – How to Copy & Paste from Ubuntu Guest to Windows Host

This works for me - with reservations! I obeyed all the standard instructions from the documentation (update, upgrade, install dkms, reboot, then install Guest Additions and reboot again).

The problems start in Full Screen or Seamless mode where it appears the the screen refresh is broken - for example you get up a Terminal and start typing - nothing happens. Click OUTSIDE the terminal and all your typing magically appears. Reverting to windowed mode fixes this and the system works including cut and paste between Windows and Ubuntu.

Open up the VirtualBox Manager, select your guest machine, and go to Settings. In General, there should be a tab called "Advanced". Make sure "Shared Clipboard" is set to "Bidirectional".
