XFX Radeon HD 4650 512mb Snow Leopard 10.6.4 Black Screen?

[spark*]

Hi,

I have installed snow leopard vanilla and updated to 10.6.4. At first I followed one of the guides on here to use the 10.6.2 kexts but i got a garbled screen. So i extracted the kexts from the snow leopard update pkg and replaced them. I then went on the HCL and found someone with the 1gb version of my card, i then followed their instructions and added my device id to the kexts. I now get a NO SIGNAL message on my monitor when booting normaly and via safe boot.

I have tried DVI -> VGA and the VGA port but no hope. Please help.

Ensure to use Motmot Framebuffer in order with 10.6.2 kexts for VGA to work.

Hi,

I have just booted back into safe mode and I get full resolution and quartzGL.

How is the situation if you remove X2000.kext?

If this makes it possible to you to boot normal /w res change, it might be a problem of incompatibility between your Frameworks and the IOAccelator, so look for X2000.kext version. This should be either 1.6.16 in case of 10.6.4 or 1.6.18 if Snow Leopard Graphics Update v1 was installed as well.

Hi,

I see the problem now. I am actually using the 10.6.2 one. Do you have the 10.6.4 one? Or should i update the snow leopard graphics? If i do do i then need to re add the device ids?

np - I am used to have the latest updates released stored to the disk....

10.6.4 / v1.6.16.11 (8209) with correct dev id for hd4650 :)
