Public bug reported:
Laptop was unable to wake up after being suspended by lid's closing,
resulting in a blank black screen, while LEDs on the laptop showed that
it had woken up. This bug happened using kernel 5.4.0-56.62, and it was
"solved" by changing the kernel used to version 5.4.0-54.60, in which
the default behavior of suspension when lid was closed and lock/login
screen after lid being lifted up ocurred as it always was.
