I own a Dell Studio 1558 with the following specs:
Core i7 7200
ATI HD 5470m
1080p Internal Display
by now, I managed to install Mac Osx Lion 10.7.2.
My graphics is working QE/CI on Full Resolution, but It didn't work the same way as described by other 1558 owners.
My Internal Monitor kept getting recognized as secondary, so I decided to synchronize the vga output with the Internal display even though there is no external display connected.
Now, that everything seemed to work, I noticed, that when scrolling oder switching between spaces the whole image of the screen seems so be split in two Rows of which one hangs back for a few houndred milliseconds.
I suppose that could've something to do with Duallink?
Another Problem and thats the main reason why I write this request is that Sleep seems to work but waking up from sleep only wakes up everything except for the display with stays black.
with sleep i mean"left klick on apple" and then (I'm from germany and my English teacher wasn't ever proud of me) "Ruhezustand" . I don't know if there is a different between hibernation and sleep.
I only know that hibernate to disk and hibernate to disk and ram works as described above, and hibernate to ram only will end in a kernel panic.
I hope, someone could look over my dsdt, the glitch with the graphics isn't that important for me, but sleep would be very nice thanks in advance.
