[Nix-dev] Intermittent Blank Screen upon Opening Laptop Lid

I should be clear, that right after the logs that I posted is just 
`Power key pressed.` `Powering Off...` and `System is powering down.`.

So the logs posted below, were 1 minute before I hard pressed the power 
button and forced it to shutdown.

The laptop also doesn't suspend when I close the lid. This is because 
it's pretty much vanilla NixOS. I didn't create any scripts for lid actions.
