I have written a python script to set the screen brightness of the pi-top on standard Raspbian. It is based on the concepts and some code snippets of pi-topOS (thanks to the programmers at pi-top!), but works without any pi-top software. A link to the github repository is attached. Your feedback is welcome. It can be used with the latest and greatest Raspbian.

I am unable to turn of the backlight using pt-brightness. That will solve my concern about energy saving.
When I launch pt-devices, this is what I get:
Devices and peripherals handled by pt-device-manager:
OS release: 4.14.34-v7+
Unknown host device
Hi. Thanks for your support. After activating SPI, the slider is working properly. But I can't get the backlight turned off. Do you have a solution?
Hello. thanks for your fast reply and your work. I gave a try on a fresh Raspbian install. It makes the "pi-top Configuration" mena available. But when moving the slider to adjust the delay ; a re-opening of this configuration window displays the slider on 0 value... Not working. Can't figure out why.
Hi Rene thanks for getting back to me i have the older pi top and 2 of the mk1 speakers i have it them both mounted either side of the pi top PROTO dont know if that would be causing issues or headaches when it come to getting it working i have them set to left and the to right be great if i could get them to work with kano as its for my daughter who ahs a presentation planned out to show kids in her class how to use raspberry pi and kano as she loves them, i got her the pi top for her 9th birthday but have struggled to get it running smoothly any help or advice would greatly appreciated :)
