I just updated to VirtualBox 4.3.16 and now when putting my guest OS in fullscreen the Unity launcher stays over the top of the screen. This makes using full screen unworkable.

enter image description here

Does anyone have a suggestion to fix this issue?

  • Your screenshot shows expected behaviour when we **maximize** then VBox window. But admittedly it is also an issue on fullscreen (HOST + F)... may likely be [bug #734908](https://bugs.launchpad.net/unity/+bug/734908) - switching to auto-hide the Launcher solves the Launcher issue but the top panel will still be in the way :( – Takkat Sep 10 '14 at 17:51

  • Oops... yep, I took the screen shot with the window Maximized. Good catch. – cprofitt Sep 10 '14 at 17:53
  • One suggested fix was to use the [4.3.17 guest additions](https://www.virtualbox.org/download/testcase/VBoxGuestAdditions_4.3.17-96003.iso), but that didn't work for me. – Richard Povinelli Sep 14 '14 at 17:05
  • This issue was fixed for a long time, and also with VirtualBox 5. With `virtualbox-5.0/unknown,now 5.0.2-102096~Ubuntu~trusty` this exact issue returned. Adding this comment so other user can see. Ubuntu 14.04 LTS – sastorsl Aug 17 '15 at 06:49

Disabling mini-toolbar in VMs settings is a temporary work-around. In the VirtualBox manager go to Settings->General->Advanced tab -> Mini ToolBar [] Show in Fullscreen/Seamless and make sure it is unchecked

It appears that this is a known issue with VirtualBox as reported on the VirtualBox forums. Presently there is no fix. Most users are rolling back to 4.3.14.

Same problem over here running Virtualbox 4.3.16 host on Windows7 and as client Ubuntu 14.04.1 (kernel 3.13.0-36-generic #63-Ubuntu SMP Wed Sep 3 21:30:45 UTC 2014 i686 i686 i686 GNU/Linux).

Found a reasonable workaround. Hit CONTROL-ALT-DELETE and make your choice to CANCEL. Guess itś related to X-server. Had it in the past with 12.04 or 12.10. Seems behavior is back again :-). Someone already raised a bugreport???

What also works is to minimize Ubuntu client when it's starting (booting). Maybe something with X-Server (X11) or the support for it on VirtualBox.
