How to Install with 'White screen' issue and no sleep trick? [Gigabyte Radeon HD 7950] [Clover]

[jwmann]

Hi guys,

 

Context and Information: 

This is my current Hackintosh build - http://ca.pcpartpicker.com/user/jwmann/saved/BJw6Mp
 

I'm currently running 10.8.5 and using FBrotate.app as a startup item to alleviate my white screen issue to login.
 

I'm trying to update to Yosemite (10.10.1)

 

I've made my installer using this method: 

sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/MyGUIDInstallerUSB --applicationpath /Applications/Install\ OS\ X\ Yosemite.app --no interaction

I'm using Clover to inject my FakeSMC and other kexts.

Here's my config for Clover incase that helps. - http://d.pr/n/1esKg/38AVJwdG

 

How I'm booting: 

I'm able to boot into the Installer, however I get a whitescreen issue and I'm not capable of doing anything.

These are the usual flags that I use to boot:

-v -npci=2000 -slide=0 -darkwake=1 

It also boots fine without any flags.

 

What I've tried: 

I've tried to perform the sleep trick, however my computer doesn't seem to respond to my sleep.

I'm attempting to initiate Sleep by pressing the Power button once and waiting.

Holding down the Power button will initiate a Forced Hard Shutdown

 

Of course the next thing I've tried is to boot the installer using the -x boot flag for Safe Mode.

This doesn't boot properly and says "No Mac OS Version" and ends up restarting.

I don't have the exact logs to this but I'm fairly certain the reason why Safe Mode doesn't work is because it doesn't inject the kexts needed for the boot to work properly.

 

Update #1:

I've tried the 4 framebuffers from this list that have the same ports as my card - http://www.insanelymac.com/forum/topic/292647-no-video-playback-on-hd7770/?p=1954322

These are the Framebuffers I tried and their outcomes: 

• Aji - White Screen issue
• Dashimaki - Black Screen ( Not working at all )
• Futomaki - Black Screen ( Not working at all )
• Hamachi - White Screen issue

Add to your current boot flag

AtiConfig=Tahiti AtiPorts=4

You don't rotate and no sleep trick also.

Add to your current boot flag

AtiConfig=Tahiti AtiPorts=4

You don't rotate and no sleep trick also.

 

Are these Clover boot flags?

 

Is AtiPorts the same as VideoPorts?

I'm already defining this within my config.plist

<key>VideoPorts</key>
<string>4</string>

Is Tahiti a framebuffer?

It doesn't seem to be listed in this list - http://www.insanelymac.com/forum/topic/292647-no-video-playback-on-hd7770/?p=1954322

 

Where did you find this framebuffer?

 

I apologize for all the questions. Just trying to learn where you're coming from.

In clover, you inject as Fbname=Tahiti

I used work out great for me.

are you using display port? maybe try a (older) different video output?

are you using display port? maybe try a (older) different video output?

I'm using one of the two Mini-Display Ports

My monitor is 2560x1440 and Mini-Display port is the only port to support sizes that big.

I'd try using my Integrated graphics card if I had monitor to use it with haha.
