Nvidia Quadro K420

[iPwnJ00]

Has anyone tried or know how I can get a Quadro K420 working in El Capitan?

When I boot into El Capitan, neither of my displays show up and I end up with a black screen (but the monitor is on).

I've tried installing the web drivers and using nvda_drv=1 flag, but still nothing. I don't have on-board graphics.

What system profile are you using?

What system profile are you using?

I am using MacPro6,1 right now.

I'm aware I have to make changes to some Apple kext, I've done that but still blank screen.

I I tried a few boot flags too but no go.

I did get a console dump that gives me error messages such as

NVDA Channel Timeout

Does that mean the NVidia drivers don't support K420? I've tried with the Web package too. No luck

Is it crashing or just not showing anything on the display? Can you boot with nv_disable=1?

No crash, the system is working (hence I can SSH in)

Yes, I can only boot using nv_disable=1 but no QE/CI.

Ok, then it sounds like kext edits didn't work. Use nv_disable=1 and follow problem 4 in this guide: http://www.tonymacx86.com/graphics/161256-solving-nvidia-driver-install-problems.html

Yep, I've done exactly that with no success.
