I am unable to maximimze the Ubuntu window.

Here's a screen shot of what I see:

Yes, guest additions would do it. – RobotHumans Oct 25 '12 at 20:29
I think this question is not a duplicate, because I would never have thought of fossfreedom's solution when asking the question. The link is not evident at first. – Agmenor Oct 25 '12 at 20:31
@fossfreedom i did as stated in the link you provided and no change, i will now take the suggestion below thanks! – l--''''''---------'''''''''''' Oct 25 '12 at 20:42
@AbrahamVanHelpsing any other suggestions?? – l--''''''---------'''''''''''' Oct 25 '12 at 21:13

As fossfreedom indicates in a comment, it is better to install the Virtualox Guest Additions first. See this question to do so: How do I install Guest Additions in VirtualBox?.

After that, if you still have your problem, try changing the resolution of Ubuntu inside Ubuntu:

  • Go to the Dash Menu (the big Ubuntu button in the top-left corner).
  • Then type "Resolution" or "Displays" to see the "Displays" app.
  • Launch it by clicking on it.
  • You should then be able to augment the resolution.

thank you ! the max display has already been set at 1024x768! what else shoudl i try? i did get the guest additions. do i need to restart windows? – l--''''''---------'''''''''''' Oct 25 '12 at 20:44
It should be sufficient to restart your Ubuntu guest for additions to take effect. Then turn fullscreen with <hostkey> + F or scale mode with <hostkey> + A (hostkey is <right Ctrl> key in your case). – Takkat Oct 25 '12 at 21:20
thank you very much, that did SOMETHING, it made the background of virtualbox instead of grey, it made it black, but the linux is still th esame size – l--''''''---------'''''''''''' Oct 25 '12 at 21:25

funny how hard you need to dig to find a solution to a problem that is very widely encountered. i guess google's algorithm isnt perfect – l--''''''---------'''''''''''' Jun 27 '13 at 20:20
It's no longer "ose" now, just sudo apt-get install virtualbox-guest-utils. It pulls in dkms. – Dan Dascalescu Dec 1 '14 at 8:54
