Sapphire ATi 4850 Black/Corrupt screen on Wake

[jasjeet]

Hi, ive had my ATi 4850 working with QE and CI for a while. I remember using ATI4800Controller.kext and EvoEnabler to make it work.

 

But i cant get Sleep to work. It goes to sleep, but upon wake, i get a black screen. Or if "Repost graphics on S3 resume" is enabled in bios, i get a corrupt image at low resolution flickering over the desktop.

 

Is there a way i can make it work?

I saw somewhere that this is a common error I have the same card and cant even get my resolution up. Your only option is to disable sleep

With OSX 10.6.2 I am using SleepEnabler.kext that I got from this post:

It works with my HD4850
