--- Comment #5 from JM9  ---
In my case, I'm logging into X without a login manager at tty1 and after a thaw
my laptop display does not come up. Not just the external display. This makes
hibernate to unusable.

I can confirm this with lenovo laptop t450s kernel 4.4 Kubuntu Xenial
i guess relation to

https://bugs.kde.org/show_bug.cgi?id=360766
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1555078

basicly this stops external displays come up after resume
but for magic if not login after resume and wait time to set brightness auto as
configured, some i.e mouse action does wake up external displays.
Speculation the drm resume code is broken.

Ubuntu mainline kernels). The trace is ever so slightly different though (line
620 instead of 619):
