You have been subscribed to a public bug:
System fails to suspend, screen goes dark then turns back on. The lid
won't suspend the system either.
Things I've tried:
turning off baloo, disconnecting from network.
>From the logs:
suspend.target: Job suspend.target/start failed with result
'dependency'.
I've observed this behavior a often enough during the past month that
suspend is unpredictable. Luckily my computer has a suspend state
indicator - some laptops don't.
A google search shows this to be a very old bug, earliest mentions are
from 2014.
