So, I recently installed Ubuntu 18.04 LTS on my 2014 Macbook Air 13inch (no dual boot). When I close the lid, the apple logo is still lit and the screen stays on. Because of this I usually press command L (super L) and then the computer will sleep. When I press a key to wake it afer, sometimes it wakes immediately but most of the times I have to wait around thirty seconds for the screen to turn on. Why?!?

I had this issue on my Dell Precision 7520 since upgrading to Ubuntu 18.04.

Upgrading the kernel from 4.15.something to 4.20.10 with Ukuu seems to fix it. Instant resume after testing it by going back to bed for an hour having closed the lid and watched the lights go out.
