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.
