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?

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.
