But I know that is wishful thinking on my part. The solution that would be highly recommended for me is the one that works in Mint which is that the ambient light sensor is used to tell the back-light what level to be at (known to work on Thinkpad and Dell). It would be great if we can get someone to help us troubleshoot this type of problem. This looks to have been resolved in UPower (but I don’t think mate uses that) as the fix didn’t work for me. I then have to turn it off again with the F10 hot key I then have to turn off again with the F10 hot key I turn off the back-light with the F10 key (Dell XPS 13)
5GHz) INTEL CORE i7-9750U PROCESSOR, 8GB RAM, 256GB SSD, 4GB NVIDIA GEFORCE GTX 1650 GRAPHICS, NO DVDRW, WIFI.
I can turn it off each stage and then the next stage it will come back on. Also, you cannot turn off the Y light on the lid.
I have the same problem and it definitely happens when transitioning through the different stages of my booting process or unlocking process.
