i have a PIR on another raspberry pi. This one should turn the monitor on this ubuntu via SSH on and off.
My System: Raspberry Pi 4 with Ubuntu 2104
I read about this and found many answers about using xset ( xset -display:0.0 dpms force off ), but the xset doesnt work ( Server does not have the DPMS Extension ). I tried to use the ubuntu screen off and use of xdotool to move the mouse to enable the monitor - xdotool also is not working. Now i found that ubuntu now use wayland and x tools are not working. For turning monitor on/off, i found that the new tool could be wlr-randr, but i get: compositor doesn't support wlr-output-management-unstable-v1. With mousemove i used wtype, but get the same error message.
What could I do to turn monitor on/off in ubuntu 2104 with xwayland via SSH?
Regards David
