I did it years ago in the following way:

$ sudo cp -av /etc/lightdm/lightdm.conf /etc/lightdm/lightdm.conf.bak
For a backup of the file you are going to edit.

$ sudo nano /etc/lightdm/lightdm.conf
Search: #xserver-command = X
Change that into:
xserver-command = X -s 0 -dpms
Then save the edited file, and reboot.

Later on I changed it to:
xserver-command = X -s 60 dpms
so now it only blanks once an hour.


I also did the following:

sudo nano /usr/share/lightdm/lightdm.conf.d/01_debian.conf
At the end of that file, add this line:
greeter-setup-script=/usr/bin/numlockx on
Save the file and reboot, and your NumLock key should still be on
Ofcourse I had to install numLockx first.
Because that was also a setting I was missing in the setup config of
Raspbian Stretch.
For the Raspberry Pi 4B you have to do these changes in Raspbian Buster.
But after that your Raspbian Buster (micro-)SDcard works in almost all (old)
Pi's, i.e. 1B, 1B+, 2B, Zero(W), 3B, 3B+ and 4B.
I never worked with the Zero and smaller A models,
but only the more capable B ones, i.e. as desktop machines.
I once tested my Eminent EM1010 USB2A to RJ45 Eth module for 10/100 mbps
networking on a friends Pi Zero with a micro USB to USB2A cable.
Good luck with it.

Greets form Henri.
