How do I maximize the Ubuntu screen when it is a Virtualbox guest?

virtualbox resolution screen

Solution 1

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 a VirtualBox VM?.

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.

here's what worked!!

sudo apt-get install virtualbox-ose-guest-utils virtualbox-ose-guest-x11 virtualbox-ose-guest-dkms

I want to run my application and have some third party app log all of the GUI events to dialogue or file.

I've moved a wxPython app from win7 to win8 and having problems where the entire system locks for five minutes everytime I scroll one of the panels.

  Yes, guest additions would do it.

  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.

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).

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

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

It's no longer "ose" now, just sudo apt-get install virtualbox-guest-utils. It pulls in dkms.
