Ubuntu 12.10 and virtual box?

[NikTh]

Guest additions included in VB program. Not needed to download them separately. Once you install your Virtual Ubuntu , click the "Devices" and last in list you will see "Guest Additions" . Click and installation will begin. You have to reboot (your Virtual OS) for the changes to take effect (and you will have full-screen VB)

Better to install the same architecture as host , but this is not a requirement.

Thanks

Most of resize methods , configured with Host+F (host=right Ctrl). Alternatively you can click on "View" and see what allows you to select.

Thanks
