Check that auto-resize is enabled in the guest. If it is and you still get black borders when in full screen the guest additions may not be installed properly. See the following link: Howto: Install Linux Guest Additions

Hi,
auto resize is greyed.

Then the guest additions are not installed or installed properly. Follow the link I sent and and see if you can get them installed properly.

The Solution was so easy. I updated ubuntu itself. Then ubuntu asked me to reinstall guest Addition and everything works fine.

Thank you for the quick help
