Hello, for automatic opening of the num lock keys, follow the procedures in the following locations.
First we build the packet from the terminal numlockx
sudo apt-get install numlockx
Then we open the default file
sudo leafpad /etc/gdm3/Init/Default
We paste the following code into the file that opens
if [ -x /usr/bin/numlockx ]; then /usr/bin/numlockx on fi
He has a file's name and numlockx etc / init, we save into folders.
