sudo nano /etc/lightdm/lightdm.conf

Add the following lines to the [SeatDefaults] section:

xserver-command=X -s 0 dpms

    I know this is old, but this didn’t work for me at first either. Make sure that what you add/edit comes after [SeatDefaults] and I think the correct command is xserver-command=X -s 0 -dpms (notice the ‘-‘ before dpms)

      I did this and it installed the screensaver but when I click on preferences/ screensaver it just instantly flashes something on the screen for a fraction of a second and then goes away. I’m running Raspbian on pi 4b – Any suggestions?
