Black Screen After 10.10.3 update

[biggnou]

If you have only one build, then it should be on your profile as per the forum rules.



nv_disable=1 will prevent the native nvidia driver from loading, so no QE/CI.



What is happening while trying to boot with this flags?? Is the booting stuck with any messages on screen??

Updated my profile. Thanks

When I try with all the flags you told me (dart=0 GraphicsEnabler=No IGPEnabler=No -f -v) it boots, but after the apple loading progress bar is 2/3rd full, monitor enters power saving mode. I can SSH it and work on it, I can see it is "fine" (at least from what I can see, but my Mac OSX knowledge is rather limited). It's just the video that does not display anything.

Set the graphics card as your primary video adapter/initial display port on BIOS.
Disable integrated graphics on BIOS (If you are not using it).

Try to boot with "dart=0 PCIRootUID=1 GraphicsEnabler=No IGPEnabler=No -f -v"

That Did not work either,

I remember that i had similar problem with mavericks and it booted with this. But This does not work with yosemite..
IGPEnabler=No PCIRootUID=1 npci=0x3000

Nvidia Driver Manager Does not find any devices on ECC.

If the screen is going black, then how you had checked the ECC tab??

Same problem. I uninstall nvidia driver, restart and black screen.
only boot with nv disable 1 dart0, but resolution 1024px

In the BIOS of my MB, under "Peripherals", I already have "Initial display output" to "PCIe 1 slot". The other choice is "IGFX", which I interpret as "intergated graphix" but I may be wrong. A little bit lower I have the "Intel Processor Graphics" parameter, and it is "disabled" already.

Rebooted with your flags, monitor enters power saving mode. But system is up and running, I can SSH it.

I modified a little bit my /Extra/org.chameleon.Boot.plist:

The UseKernelCache was previsouly set to Yes, dunno if this can have any impact though.

I checked ECC when i booted with nv_disable=1 -f

Clear NVRAM and check the booting.

Disable the graphics injections as below,

<key>GraphicsEnabler</key>
<string>No</string>

<key>IGPEnabler</key>
<string>No</string>

Then Clear NVRAM and check the booting.
