For Ubuntu Gnome 18.04+

When you are at the login screen the user ID active is gdm (Gnome Desktop Manager). To change that profile login with your own user ID and use:

sudo -i
xhost +SI:localuser:gdm
su gdm -s /bin/bash
gsettings set org.gnome.settings-daemon.peripherals.keyboard numlock-state 'on'
gsettings set org.gnome.desktop.peripherals.touchpad tap-to-click true

For a plethora of even more options:

For Ubuntu Unity 16.04+

Install the the program numlockx:

$ sudo apt update && sudo apt install numlockx

$ numlockx -h
NumLockX 1.2

Usage: numlockx [on|off|toggle|status]
on     - turns NumLock on in X ( default )
off    - turns NumLock off in X
toggle - toggles the NumLock on and off in X
status - gets the NumLock status

Next step is to get it running during login screen:

$ locate 50-unity-greeter.conf

$ sudo -H gedit /usr/share/lightdm/lightdm.conf.d/50-unity-greeter.conf

At bottom of file add:

greeter-setup-script=/usr/bin/numlockx on

Save file and login again.

Catchall when everything fails

Install numlockx as show above. Then

$ sudo -H gedit /etc/rc.local

At bottom of file add:

/usr/bin/numlockx on

Save file and reboot.
