UltraBloxX Posted April 14, 2019 Posted April 14, 2019 It is possible to drag backlight control slider to far left position and this completely dims the screen's backlight. This might cause a lot of trouble, if backlight levels get saved by systemd service, as it will persist across reboots and will require you to shine a flashlight on a screen to actually see something and turn backlight back on.

This feature is under development - its low level panel/pwm driver problem. Since development is mainly amateur based and since there are at least three different panels on Pinebooks ... things go slow.
