Hi, in my case I can see something on the screen after reboot, but
very dark. This hints that the problem in a backlight, and it is so:

#+begin_example
cd /sys/class/backlight/intel_backlight/

cat brightness
0

cat max_brightness
4437

cat max_brightness > brightness
#+end_example

The last command (run from root) makes my screen light up again.
