10.10.3 Update Black screen with cursor

[fleisch]

Now my Hack shows a Supplemental Update concerning video drivers?! What's up with that? Is it safe or will my 7750 go back to no signal after boot... maybe they fixed it?

Hi, I've managed to get it worked.
The problem is in the new AMDRadeonX4000.kext.
The new values in 10.10.3 for "cail_properties" of AMDVerdeGraphicsAccelerator driver are:
<dict>
<key>CAIL_DisableDrmdmaPowerGating</key>
<integer>0</integer>
<key>CAIL_DisableDynamicGfxMGPowerGating</key>
<integer>1</integer>
<key>CAIL_DisableGfxCGPowerGating</key>
<integer>0</integer>
<key>CAIL_DisableGmcPowerGating</key>
<integer>1</integer>
<key>CAIL_DisableStaticGfxMGPowerGating</key>
<integer>1</integer>
<key>CAIL_DisableUVDPowerGating</key>
<integer>0</integer>
<key>CAIL_DisableVCEPowerGating</key>
<integer>0</integer>
</dict>
The old values (in 10.10.2) was:

<dict>
<key>CAIL_DisableDrmdmaPowerGating</key>
<integer>1</integer>
<key>CAIL_DisableDynamicGfxMGPowerGating</key>
<integer>1</integer>
<key>CAIL_DisableGfxCGPowerGating</key>
<integer>1</integer>
<key>CAIL_DisableGmcPowerGating</key>
<integer>1</integer>
<key>CAIL_DisableStaticGfxMGPowerGating</key>
<integer>1</integer>
<key>CAIL_DisableUVDPowerGating</key>
<integer>0</integer>
<key>CAIL_DisableVCEPowerGating</key>
<integer>1</integer>
</dict>
Once I change it back in Info.plist and clear kext cache, my system boots without problems.

It worked for my 7850m card. Thank you so much!

it really works, thanks very much

here is how to:
use -v -s booting args to boot into single user mode
mount -o update /
cd /system/library/Extension/AMDRadeonX4000.kext
edit the info.plist under kext by vi or other text editor
save your edit then reboot with -v -x (into safe mode)
login then use kext wizard to rebuild the cache (with out 3d acceleration,it's very very lag...)
after kext rebuild , reboot, all down and it works!

Take it from attachment.

it perfectly worked with 10.10.3 , but doesn't with 10.10.4 any ideas?

For those who wish to avoid AMDRadeonX4000 kext editing, you can give a try to verde.kext which do the same exact job and will not be overwritten by OS X updates.

Works fine !

10.10.5 Update Black screen with cursor

Hello,
I have recently updated to 10.10.5 and I have the same problem. When I boot using Clover, I get a black screen on my two monitors, with the mouse cursor in upper left corner. I can move it, etc., caps lock works.
If I boot (without boot flags) using Chameleon on my original installer USB key, then I get the same result, but with an Apple-grey (or gray?) background.
I've tried different boot flags, no worked.
Is there something I can do like with the kext for the Radeon X 4000 kext?
Also, according to the OS X volume, the files that were modified in the update (in the System\Library\Extensions) are IOGraphicsFamily.kext, IONDRVSupport.kext, IOPCIFamily.kext, System.kext, AppleBacklightExpert.kext and AudioAUUC.kext.

Plz I don't want to reinstall everything, it took me 3 days to make it working...

EDIT: Also I am using an Asus GeForce GTX 760 192-bit
EDIT 2: I downloaded the latest nVidia drivers (346.02.03f01) and copied the kext files in \System\Library\Extensions, now when I boot using Clover, I get exact same as before, except that at 50% of the progress bar, instead of opening the black screen with cursor like previously, I get a small "loading" circle icon. It's been staying there for around 15 minutes and nothing happened. If I boot using the installer USB key with the boot flags "dart=0 nv_disable=1 GraphicsEnabler=No IGPEnabler=No -f -v" I get lots of stuff then kernel panic "a freed zone element has been modified in zone kalloc.64". Otherwise, it freezes at "[IOBluetoothHCIController][start] -- completed"

Thanks very much

Install verde.kext and you're done.
