Funky frank Posted April 30, 2011 Share Posted April 30, 2011 Hi, I used this guide to enable my ATI HD 4650 1GB (devid 9498): link. This guide includes a bunch of patched ATIXXXX.kexts. Full resolution and Quartz acceleration works fine. If the computer goes to sleep ,or the display powers off after a while, the display will not wake up again and remains black. I can hear still audio and see harddrive access. But there seems to be a wakeup functionality missing. How can I fix this? Is this a driver problem or can I patch it by adding wakeup calls to the dsdt? It also happens when I change the screen resolution. So it's not a power management, but ati kext related problem... Any ideas? Link to comment Share on other sites More sharing options...

Funky frank Posted May 18, 2011 Author Share Posted May 18, 2011 It was caused by a wrong personality in the ATIFramebuffer, here is a solution for a working DVI-out with full acceleration/wakeup/screenres-change. It seems that the order of the ports in the personality has to match the the order of the ports in the bios dump. Link to comment Share on other sites More sharing options...
