dpms force off doesn't work

[Guest]

Hi Friends,

 

on Banian I was using "xset dmps force off" and "xset dpms force on" to switch display off and on as I need it. Tryed to use this commands in terminal with armbian but nothing happens.

I'm using LeMakers 5" LCD RGB Display with PCAP Touch. Armbian is 5.24 jessi with desktop and 4.8.12 Kernel.

 

Has anyone an Idea, how to turn off and on display form terminal?

 

Yours,

Martin
