Details

Packages: Linux 4.2.2-1-ARCH
Architecture: x86_64
Plattform: VGA Intel Bay-Trail Atom Processor Z36xxx/Z37xxx Series Graphics & Display
Devices affected: Intel NUC D2820FYKH, Asus J1800I-A, Zotac ZBOX CI320...
Monitors testet: BenQ GL2450 (HDMI)/ acer AL1923 (DVI)

Description:
In console without X started after a few minutes monitor connected via DVI or HDMI goes to power save mode (sleep) and powers down. Now you are not able to wake your monitor again - only way to get monitor on again is to reboot.
Even when starting X blindly monitor stays off.

What it should be doing:
Monitor should wake up on keystroke or mouse movement or even power up on starting X

I have a Zotac ZBOX CI320 and I can confirm this issue!

Maybe this bug has something to do/is related to this bug:
https://bugs.freedesktop.org/show_bug.cgi?id=88012
https://github.com/OpenELEC/OpenELEC.tv/issues/3726

As far as I understand it the Bay Trail GPU driver is broken, when it comes to powersaving/switching between power states.
