برای من این کار کرد:
First, ensure that numlockx is installed, by typing these in terminal:
sudo apt-get install numlockx
Then, edit the file /etc/lightdm/lightdm.conf
gksudo gedit /etc/lightdm/lightdm.conf
Add the following line to the file:
greeter-setup-script=/usr/bin/numlockx on
For Enabling Numlock by Default after Logging In.. In Dash Search for Keyboard Layout and open it
In the window that opens on the ottom right there is Options, click on it.
Under Miscellaneous compatibility options, Enable Default Numeric Keys.
