How to enable numlock at boot time for login screen?
Here's what worked for me:
Ensure that numlockx is installed:
sudo apt-get install numlockx
Edit the file /etc/lightdm/lightdm.conf
gksudo leafpad /etc/lightdm/lightdm.conf
Add the following line to the file:
greeter-setup-script=/usr/bin/numlockx on
Cool, thank's.
Four years latter still works in Sparky 4.8.1 2018 - THANKS
Is there something else besides just installing the tool?
Unfortunately, it doesn't seem to be working in my case. the numlock light flashes a few times at boot time, but then remains turned off for the logging.
I've tried both greeter-setup-script=/usr/bin/numlockx on and greeter-setup-script=/usr/bin/numlockx toggle, the result is the same.
