Summary of my tests
WORKS:
* Ubuntu 16.04.6 LTS (xenial), clean install and after updates as well
* Ubuntu 16.10 (Yakkety Yak), clean install and after updates as well

FAILS: (no DPMS)
* Ubuntu 16.04.6 LTS (xenial), with HWE kernel
* Ubuntu 17.04 (Zesty Zapus)

I tried some APT pinning to test kernel combinations:
WORKS:
* Ubuntu 17.04 (Zesty Zapus), with kernel from 16.10 using apt pinning.
FAILS:
* Ubuntu 16.10 (Yakkety Yak), with kernel from 17.04 using apt pinning.

So I'm convinced it's something in the kernel package. Could be the options the kernels are compiled with, or something upstream?
