Nvidia Injection Works on Yosemite but not El Capitan

Hey guys,

 

I finally made the plunge to upgrade my system to El Capitan from Yosemite.

 

I used the same Clover configuration from my Yosemite installation but for some reason, the Nvidia injection is not working.

 

My system will boot up and then eventually, I'll get 1 of 4 possible scenarios:

 

1. The monitor will blank (but there is still signal)

2. The login screen will show for a brief moment, then go to a black screen (same as 1.)

3. I get a black screen with a white cursor, like when the system is loading in verbose and it will be stuck without any text.

4. I get a cursor but nothing else. The cursor can be moved.

 

Does anyone know why this would happen? It worked perfectly fine in Yosemite.

 

I'm starting to consider whether or not I should extract the Nvidia drivers from Yosemite and put them into El Capitan, but I don't have my Yosemite installation anymore :/

 

Thanks!

 

EDIT:

Forgot my system specifications;

 

I'm on a Lenovo ThinkStation P700 Workstation

 

CPU: 2x Intel Xeon E5-2620 v3 (Haswell-E)

RAM: 16 GB

Graphics: 2x Nvidia Quadro K420 (have tried with just one but still doesn't work)

We can't help you if you don't tell us your hardware specs....

 

Oops, sorry!

Try use this boot-arg: PCIRootUID=0

 

Thanks, just tried that but now I'm getting glitchy graphics; what happens is the screen will load with the verbose text in the background and random lines of colour throughout the screen.

 

I know it's my desktop because I can see pixels moving when I move the mouse.

An update:

 

I tried to get the Nvidia drivers from my Yosemite installation disk and replacing (as in deleting NVDA*.kext and using Kext Wizard) the El Capitan included kexts but still no luck.

 

Most likely means that they've change some display-related things in El Capitan...
