[Solved] No Graphics after 10.10.3 upgrade

[veghead42]

I've been happily running a custom box with a GA-797X-UD5H motherboard and an Nvidia GT 740 graphics card (EVGA GeForce GT 740 2GB FTW). After installing the 10.10.3 upgrade, my setup was working but I was seeing a lot of instability with the onboard NIC. So, I re-ran MultiBeast (settings listed below) and on my next boot I didn't have any video. Everything seems to work right up to the point where it should display the login screen; at that point, the screens go blank (and quickly go into power-saver mode).

Following some advice on the forums surrounding the 10.10.1 compatible Nvidia drivers, I booted the system with -x and nv_disable=1. That worked, albeit in a super low-res mode. I then installed the latest Nvidia drivers based on this post. Then I rebooted, but I'm still having the same problem.

Any suggestions on what else I should check?

Thanks!

After installing the drivers you have to boot using nvda_drv=1 to use the drivers.

Yeah, that's what I figured. Sadly, that didn't work. Manually specifying "nvda_drv=1" as a boot parameter seemed to have no effect; the screen still goes blank. I even checked /Extra/org.chameleon.Boot.plist and added nvda_drv=1 to Kernel Flags (it was missing).

On further testing, I can boot the system in safe mode with "-x nv_disable=1" and successfully log in. But if I boot the system with just "nv_disable=1" (not safe mode), I get the login screen but then it hangs on login.

Ahh, I just notice you are using a MacPro6,1 system definition. That is the problem, either use something besides MacPro6,1 or iMac15,1 or follow these steps to fix it: http://www.tonymacx86.com/graphics/161439-gtx-970-black-screen-after-nvidia-346-01-02f01-2.html

We've seen too many problems with the iMac15,1 and MacPro6,1 SysDefs. Update your nVidia drivers with the safe MacPro3,1 then change to iMac14,2 (toleda recommends). Works for me.

I personally use 14,2 as well.

Boom! That was perfect. Exactly the problem. I should know better than to change more than one setting at a time. *sigh*

Thanks!
