<pre>Hi,
I reported a bug upstream @Plasma (<a href="https://bugs.kde.org/show_bug.cgi?id=365455">https://bugs.kde.org/show_bug.cgi?id=365455</a>)
and KDE developers discovered the issue is in the Intel driver: the modesetting
fails on the screen and that's why it goes off. I can trigger switching the
display on by going through a dpms cycle. I have the very same issue with
modesetting and with kernels from 4.4 to 4.7, so I'm not sure where the problem
may be. In the linked bug report you can find logs and much more informations,
including some videos.
Please let me know if you need anything else, I'm at your disposal.
Thanks,
Niccolò</pre>
