I have Windows7x64 and Oracle VirtualBox 4.1.18 installed on it.I installed Ubuntu 12.04x64 and when I use it, mouse scrolling(Logitech M175) is not working. What I should do to make it work?
The problem was with guest additions I installed them via windows and they didn't work proper. After it I reinstalled them at Ubuntu and everything is working.
I've found this happened because VirtualBox thought I was holding the Alt key. Focusing the guest OS and tapping Alt a few times seems to restore proper scrolling.
I can now reproduce this at will with the following sequence of operations:
- Switch out of VirtualBox to another program
- Hold down Alt key
- Click of VirtualBox window
- Observe that the scroll wheel has stopped working
As mentioned in this question's answers:
You should update to the latest VirtualBox and extension pack, and reinstall vbox addition. Everything works fine after it, tested minute ago.
This is the correct way to fix this problem without losing functionality, although sometimes, disabling mouse integration is the only way to go.
