How do I adjust screen luminosity
#1
Hi
I just received a new screen by Waveshare (10.1inch, IPS, 1280x800 HDMI, capacitive touch control). It worked 'out of the box'.
It avoids the drawback of the "too small" 7 inch which was limited to 800x480, and did not allowed to reach the OK button in many windows ...
It can hold on his back the RPi cards plus HATS (holes pre-drilled, and screws and spacers in the package).
Off course its packaging implies an installation down below, at the navigator station.
The intensity under 5.2V is below 0.9 Ampere, consumption 4.7 W ! (My older 'office type' screen needed 2.7 A x 12.4 V = 34 W, - 7 x higher !)
No OSD, nor luminosity H/W control...

Now my questions : Is there a software way to control the display luminosity ? 
In Navigatrix an utility called Redshift is available, which does the job. Is it, or could it become, applicable to OpenPlotter?
Or is there any known alternative ? (even a manual solution would help )
