I've recently faced with a strange problem of lacking QE/CI acceleration on a fresh 10.10.4 install on my Samsung NP900x3c, i7 ivy, HD4000, 1920x1080, ALC269VC, no dsdt patches, Clover 3259 bootloader. The thing is that with the same Clover config I can boot 10.9 and have full acceleration while 10.10 is booting but no QE/CI. Another thing is that 10.9 provides desktop and QE/CI only with the following ig-platform-id: 0x01660002 0x01660008 and 0x01660009, other ig-platform-id prevents 10.9 from booting, while 10.10 provides fully functional desktop with any ig-platform-id but no QE/CI at all
Today I tried a new config.plist based on on rehabman's https://github.com/R..._1366x768.plist with only little fixes and patches in it to make the system boot without patching dsdt.aml I tried these ig-platform-id: 0x01660002, 0x01660003 and 0x01660004, I tried with and without dual link patch, with and without MacBookPro9,2 No success. I have neither transparent menus nor screensaver preview. Meanwhile, with the same rehabman's config with ig-platform-id 0x01660002 I can have QE/CI on my 10.9. The only difference is that 10.9 is started from SSD while 10.10 from an external usb drive. But I don't think it might be a reason of this graphic acceleration problem. Just in case, I attached the config file I used.
Any help would be very much appreciated.
