GTX 285 Black Screen

03 November 2014 - 06:13 PM

I've searched the forum but I haven't noticed that anybody have issue like this.

Supermicro X8DAE motherboard
Dual Xeon (8 cores, 16 threads)
NVIDIA Geforce GTX 285, 2GB VRAM (DVi, HDMI, VGA)
MacPro 5.1 Smbios definition

I have installed Yosemite W/O any major issues but than came to a problem that I can not solve. What ever I do, if I boot normally, I get black screen/s. And I'm not talking about "DVI Signal Not Found" - I get black screen with cursor over it. I can move the cursor but that's it. (this happens after boot sequence, before login screen should come up)

I can boot to Desktop with safe boot (-x) or with nv_disable=1, so I guess this is GPU issue

What I have tried by now:
- all possible different boot loaders (Chameleon, Clover)
- default OS X driver and NVIDIA web driver (nvda_drv=1)
- combination of different boot flags

Does anybody have any idea what else could I try?

Thank you in advance.
