You should have described this in the beginning.
The bug originally was:
"The screen after the grub is getting black ( backlight is still working ).
System is booting normally - after that backlight screen is working .. and
black all the time.
I can control brightness by shortcuts.
If connect HDMI cable then on the new via HDMI the screen works perfect but on
the device screen is still black unfortunately .
I attached the kernel.
