Hi all,
Feeling like I'm losing my marbles here. Can anyone chime in and nudge me into right direction?
I have a Skylake that runs pretty good, apart from problem described, no signal after waking from sleep.
Mobo: GA-Z170M-D3H
CPU: 3,5 GHz Quad-Core Intel Core i5
Memory: 32 GB 2133 MHz DDR4
iGPU: Intel HD Graphics 530 1536 MB
dGPU: GeForce GTX 750 Ti - disabled with -wegnoegpu boot arg
All kexts to latest vesrsion - LiLu, WEG etc.
I was hoping that WEG igfxonln=1 boot arg would resolve this, but to no avail. Tried other monitor port and other HDMI cable as well.
Complete boot args: debug=0x100 keepsyms=1 alcid=1 igfxonln=1 -wegnoegpu.
Hardware acceleration is supported on iGPU and video memory looks OK, 1536 MB.

The computer will go to sleep and will wake up, but without HDMI signal. Sometimes it will throw this:
