[ubuntu] How to get VBox Shared Clipboard to work?

I have VirtualBox 4.2.12 installed manually on Ubuntu 12.04.

I created a VM of headless ubuntu-12.04 server and that has worked fine using PuTTY session between host and guest.

But I hit problems in trying to copy/paste text in the PuTTY session terminal.

I saw that this needed Guest Additions and I managed to install this..

Then in Preferences > General > Advanced
I set ...

• Shared Clipboard: Bi-directional
• Drag'n'Drop: Disabled

But I still can't copy text from host clipboard into guest command line session.

What more steps should I take for shared clipboard to work?

I can see from my searches that others have hit the same problem ... but few solutions found ...
