   The easiest way to disable screen blanking in the Raspbian GUI is to install xscreensaver then configure it to disable:

   sudo apt-get update
   sudo apt-get install xscreensaver

      Thanks a a lot. I tried all of things have failed. But, this is working correctly.

      This was by far the easiest solution. Thanks. Managed to get the dashboards setup for https://www.rixxo.com/ in our office without the screen going black every few minutes

      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?

   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)
