I've installed on my host ubuntu 10.04 in virtualbox guest operating system ubuntu 12.04. And mouse wheel doesn't scroll vertically the contents of a window. In host works normally. VirtualBox mouse indicator in the right bottom corner flashhes when I'm using mouse wheel.

    Have you installed Guest additions?

    Installing the guest additions made the mouse wheel work (Guest OS was Mac OS X 10.8) Aug 31, 2012 at 14:51

I also had this same problem, other distros in VirtualBox accepted mouse wheel scrolling without a problem.

My fix was in the "Machine" menu of the VirtualBox window in which Ubuntu was running, select "Disable Mouse Integration". Mouse wheel scrolling works after that.

I am using a wired mouse into a PS/2 port on the host.

  • Worked for me thanx!

  • Note that mouse wheel scrolling should work with mouse integration. Feb 19, 2016 at 23:25

    This has since moved to the Input menu instead of Machine

You should update to the latest VirtualBox and extension pack, and reinstall vbox addition. Everething works fine after it, tested minute ago.

    This. That way, you don't have to disable mouse integration, which I find very handy.

  • This is the actual answer, since you don’t lose any functionality when you do this.

  • As long as the latest extension pack is fully compatible, yes. Otherwise disabling mouse integration is the only thing that works. Some oddity is preventing that at the moment. Aug 2, 2013 at 17:58
  • I updated VBox a couple of days ago and installed the extension pack and I have this problem. The "disable mouse integration" works. (VBox with ubuntu 12.04 running on mac 10.6)

In my case, (Lubuntu 13.04), while the Disable Mouse Integration hint works, I installed virtualbox-guest-x11. This enabled me to use the mouse wheel
