Cannot use Nvidia Optimus with proprietary driver since beginning of February 2016 (I have moved into Plasma 5 that time).

I posted it on freedesktop buglist a month ago:

I posted it on Nvidia buglist a month ago:
https://devtalk.nvidia.com/default/topic/928743/cannot-start-x-from-february-2016-nvidia-optimus/

I was trying to dwongradeand different (xorg-server, intel & nvidia drivers ) and was trying latest drivers - nothing works.

Since February 2016, there is only 1 error Xorg.0.log, which only occur in Gentoo:
(EE) modeset(G0): failed to set mode: No space left on device
^^ So I am thinking what is goinng wrong? Eselect-opengl? Maybe any Gentoo path?

Reproducible: Always

1. startx from text console
2.
3.
Actual Results:  
Black screen

Expected Results:  
KDE Plasma 5 or pure X system
