virtual-machine - NumPad keys dont work

Question

I had this problem on the virtual box virtual machine running Ubuntu, that some times, the numpad keys worked and some times they didn't. I thought it was some bug, or some issue with the guest additions, or even that it was related to starting the virtual machine while the numpad led is activated.

Nothing like that. I though I could share the solution.

Answer 1

The solution is quite simple:

System -> Preferences -> Keyboard -> Tab "Mouse Key" -> deactivate "Pointer can be controlled using the keypad".

And the numpad keys work fine.

Answer 2

当我在笔记本电脑上使用Ubuntu 15.10时也出现了同样的问题。

可以通过关闭此选项（鼠标键）简单地解决。

希望这对虚拟机也有帮助。
