screen on max

When setting the brightness to 0, either on kde with the brightness controls or with `brightnessctl s 0` the screen turns off. Then when trying to turn it back on with the brightness controls, it says off. 

The OS didn't get the OFF signal somehow. All the values in /sys/class/backlight/intel_backlight seem to indicate this.

I attached the output of `grep -r . /sys/class/backlight/intel_backlight/` for the three scenarios:
1. Screen max on
2. Screen brightness 0
3. Screen should be on, but still off.

inxi output:

I suspect it is related to OLED. The bug doesn't present itself too much in GNOME as this DE doesn't lower brightness to 0.

Screens can be turned on again by playing with dpms off. Issue presents itself in both wayland as X.
