# What happens:
In Ubuntu 16.04 / elementaryOS, after session logout, I get a black screen (screen is off, not illuminated as a black background), with no user input options, and unable to switch to consoles using Ctrl+F1/F2/etc.
# What should happen:
Go back to the session greeter where I can log in again.
# How this happens:
This happens after a couple of hours of intensive use (4 Gb of RAM almost maxed-out, swapped about 2Gb on an 8Gb partition).
If I use the computer for a half hour or so, this problem doesn't happen.
# Workarounds tested:
- Disabled services such as MegaSync and Dropbox, problem persists.
- Switched kernels: 4.4 LTS series (currently 4.4.0-133-generic) and 4.13 & 4.15 HWE series; problem persists.
- Switched xorg stack versions: xorg regular / LTS and the HWE branch; problem persists.
