#Making your numeric keypad work on a Xubuntu 20.04 VM (VirtualBox)

I fought with this for a good 2 hours before I finally got it working. First step is to install numlockx, if it's not already installed:

sudo apt update
sudo apt install numlockx

Enable your Num Lock in your VM:

numlockx on

Now in Xubuntu, go to your Whisker Menu (or whatever launcher/menu you're using) and navigate to Settings -> Accessibility -> Mouse and disable Use mouse emulation.

If you're on vanilla Ubuntu (GNOME), or a DE other than XFCE, you may be looking for a menu called Universal Access, wherein you'll want to disable a feature called Control the pointer using the keypad.

You may need to log out and back in to confirm this works.
