Hi, i have a Notebook PC with switchable graphics: HD5470M and a Intel HD Graphics! Do you know how to activate the HD5470M? There's no settings in BIOS to boot with dedicated video card.

P.S.:I have already injected my EDID.
Thanks in advance,
-giofrida

1. At boot Lion loads Ati5000Controller, AtiSupport and AtiRadeonX3000.
2. In org.chameleon.boot.plist:
  • <string>Aticonfig</string>
  • <key>Hoolock</key>
  • <string>GraphicsEnabler</string>
  • <key>Yes</key>
3. Screen already injected (EDID).

However Lion boots with Integrated Graphics and so the kexts loaded are useless.
Then, suggestions? :hammer:

Dang it, I can't get this to work. :( Hmm, maybe it has to do with the fact that I can't boot from my hard drive (I have to use my USB stick with Chameleon to boot).

I'm having the same problem as giofrida. I have 2 cards in my laptop, but no matter what I do, Lion uses the crappy Intel graphics. I can't disable them in the BIOS. Am I stuck like this?

Sigh...will I have to edit the framebuffers and stuff? My card is an ATI Mobility Radeon HD 5470 512 MB version. And if so, how should I do that? These kexts don't do anything for me, but they do allow Chameleon to properly detect my graphics card, but OS X doesn't detect it.

Finally,

The current best solution for Lion and Mountain Lion is

AtiConfig=Bulrushes GraphicsEnabler=Yes

Hey, does this works for the "i3 computers"?

I have
ATi 5470M, like you, but also intel hd1000... from my arrandale cpu!

In LION, it's only shows the arrandale graphics card (0046, i believe).

Will this work for me?

Yeah, I kinda figured it out: Most HP laptops will NOT work with this method because their BIOS does not let a card be disabled during boot. The only way to fix this is to change the Graphics Mode to Discrete in the BIOS, but most HP laptops have this missing. Some people on Bios-Mods.com have tried modding their BIOS for discrete graphics, but using it has caused bricked laptops.

I tried this and it works. But the only thing i am not getting at all is that whenever i use GraphicsEnabler=Yes, my laptop's diplay goes black/blank and shows nothing.

i somehow managed to capture the screenshot from the TightVNC acessing from the other pc.

In the Screenshot u'll see that it is recognized by the system, and also the graphics memory but there's no Display shown in the System profiler.

 

Please tell me what should i do to make the laptop screen working.
