There are still few things to change in the DSDT, I will make another DSDT with Ipomoea framebuffer (maybe it will make some difference), I will also patch some kexts for you with encoder 00

Now, back to Trucking 'n' Rolling :thumbsup_anim:

Attached File  DDT.aml.zip   64.9KB   49 downloads This one should fix VGA, report back with ioreg.

Attached File  Ipomoea DSDT & ATI6000Controller.zip   308.2KB   26 downloads This one is the same but with Ipomoea framebuffer, patched 10.7.5 ATI6000Controller.kext is included in the archive.

Perfect, i tried to use the EDID by freeuser16 but I get the opposite efect, the same as you without the edid. I need to find a closer match to my EDID and i think that we can fix the gradient colors on 6650M.

I'll be offline next few days. Well, it's not working for you, so obviously something is different. Which kext you use?

Sleep works almost perfectly for me with some DSDT edits, it goes to sleep the first time i close the lid, the other times i have to press the power button to go to sleep. My ethernet also dies when it wakes up from sleep, but wifi seems to be fine.

Yes I tried that kext, it worked, sleep also but I was getting black screen on wake. That was when I updated to 10.8.3. I reverted back to clean 10.8.2 as it's working almost perfect for me and never tried it again. So, without the USB 3.0 kext sleep/wake works if you patched AICPUPM.

@Tauio111, VGA really works perfectly with custom EDID? It doesn't even show the screen when it's not connected?
It's a bit strange solution, since VGA screens may be very different and have different resolutions. I don't know if it's correct to use EDID from one particular screen for all VGA devices :/

It does show the screen when its not connected but that can be fixed by using the mirrored mode on 1366x768.
What if someone would make a custom EDID with all the standard resolutions?

Then it means it's not working perfectly. Theoretically it shouldn't show that screen at all when VGA cable is not connected.
I think it's maximal resolution that matters in EDID, not all standart resolutions. But I'm not sure.

Well it doesnt work perfectly, but it is not that big of a deal. I've got bigger problems like ethernet being unusable after wake from sleep.

Try to remove it and add it again in Network Preferences, maybe it will work, it's easier than reboot.

I've tried doing that, it wont help. There is another kext for AR8151 which works after waking from sleep, but for some reason it does not allow me to change the mac address

  • There was a workaround about the changing MAC address, i used that on my old Aspire 8735ZG, i even had some script to do it on boot, i'll check if i still have it somewhere, but not sure.
