funktioniert hat aber nur:

You need to edit your script that's starting X. In the default build with lightdm the file to edit is

/etc/lightdm/lightdm.conf

in the SeatDefaults section it gives the command for starting the X server which I modified to get it to turn off the screen saver as well as dpms

[SeatDefaults]
xserver-command=X -s 0 -dpms

nano /home/pi/.config/pcmanfm/LXDE/pcmanfm.conf
