Troubleshooting • Re: Raspberry CM4 pwm-backlight duty cycle missing

Ok, solved

Was really a X11 "issue".

backlight power was set to 4.

Code:

# cat /sys/class/backlight/rpi_backlight/bl_power 4
According to https://www.kernel.org/doc/Documentatio ... -backlight this is power-down.

Setting it to 0 started PWM.

So everything working fine Image may be NSFW.
Clik here to view.
