In the deepin v20 beta it was possible to adjust the screen brightness to less than 10%, and that was very comfortable for me, because I have a high sensitivity to light, and because I spend a lot of time in front of my laptop. But now, the new version of deepin only lets you decrease the brightness by up to 10%, and that is really uncomfortable for my eyes. Therefore, I think it would be very good to allow the user to set the brightness they want, even if it is less than 10%. Thanks in advance!
