black screen after hibernation




I have strange problem with hibernation (to disk) on my laptop.
After resume my screen remains blank.


(It is similar to
https://lists.debian.org/debian-user/2017/01/msg00177.html, but in my
case it is regardless if monitor was off before hibernation)

System appears to be alive  (can ssh to it, and can see my running
processess)
Keyboard working (I can enter password, and enter some text "blindly")
But I cannot turn on my monitor.

I tried to play with:
echo 2000 |sudo tee /sys/class/backlight/intel_backlight/device/intel_backlight/brightnes

but without success.

There is not suspected in logs except:

After suspending to ram, there is no problems.
