My last temporary solution on that issue:
After locking screen,
When the screen goes to black
I press any key
Than the brightness of screen comes back
And never goes to black.
But
If I forget to press any key
Or after reboot if I cannot login on the time,
Screen goes to black and the solution is reboot the system.
