Also there's a few different power saving modes being activated here.
One's just the screen turning off. Which happens when I stop interacting
with the computer for a bit. As soon as I move the mouse, everything
comes back. This is fine. This does not have an intermittent persistent
blank screen.
Second is the actual `systemctl suspend` command. I've used that, and it
works. It actually turns off all the lights, and my fan stops. This also
does not have the intermittent persistent blank screen.
Third is the problem I have, is where I close the lid, wait and reopen
it. I don't actually know what's happening here. But the screen goes
blank like situation 1, but of course this is one with the intermittent
persistent blank screen.
Thanks,
Roger

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.

The error is follows (from journalctl -b -1):

Looks like something to do with stalling and CPU 7 and NVIDIA?

Hi Nixers,
I discovered this problem a while ago, basically upon closing the
lid and
reopening it after 10 min, the screen stays blank, and I can't do
anything.
Even switching to tty1 doesn't work.
This doesn't always happen. And when I close the lid and reopen
after a few
seconds, it usually works and displays something.
What are the steps that I can take to debug this issue.
It was happening back on NixOS 15.09. and is continuing on 16.03.
I'm running NVIDIA and using NVIDIA video card driver.
Did you check the system log?
