Lenovo IdeaPad 320 laptop doesn't wake up after suspend
I have a Lenovo IdeaPad 320 laptop with Debian testing/buster and Linux
4.18.5. When I close the lid and open it again, the screen is black, and
I can't do anything. I can't even ctrl-alt-F3 to a vterm. At this point
I need to restart the laptop every time I close the lid.
Does anyone have any suggestions how to fix this? I have
CONFIG_SUSPEND=y set in my kernel.
