At one point (8 months ago?) manjaro had that problem,, tiny backlight value
It was from a change in the number range, IIRR

Good idea but, because of the way the backlight flickered a few times when I moved the display back and forth and then went completely dark, I think it's a hardware problem. However, no harm in trying. On Armbian:

Code:
@pinebook-pro:~$ cd /sys/class/backlight/edp-backlight
@pinebook-pro:/sys/class/backlight/edp-backlight$ echo 3200 > brightness
-bash: brightness: Permission denied
@pinebook-pro:/sys/class/backlight/edp-backlight$ sudo echo 3200 > brightness
-bash: brightness: Permission denied
@pinebook-pro:/sys/class/backlight/edp-backlight$ sudo su
root@pinebook-pro:/sys/devices/platform/edp-backlight/backlight/edp-backlight# sudo echo 3200 > brightness
root@pinebook-pro:/sys/devices/platform/edp-backlight/backlight/edp-backlight#

Only sudo su... worked but the screen is still black. Cry

Again, thanks so much for the tips. It might have taken me a long time to find an OS like Armbian and I was also lucky that my PinePhone dock was a usable Ethernet dongle!
