I have been trying to get my Lenovo G570 i5 2430M with HD3000 (id: 116) to work for almost 2 months. Mountain Lion works flawlessly but Mavericks onwards, display stays off with the exact same setup (Chameleon: Extra folder with smbios mbp8,1 included in attachment)
I'm able to boot and see the screen with remote desktop but internal display stays off.
found an old post which fixed issue for few users
I understand HD3000 is natively supported till High Sierra, which is why I'm totally baffled and out of ideas to proceed with.
My configuration is:
Dell XPS 13 9300
Core i7-1065g7 (G7 Iris plus graphics)
16 GB RAM
UHD+ monitor (4k: 3840x2400 Touchscreen)
The problem that i am currently experiencing is that the internal display is recognised but for some reason is not functioning the way it should. The internal display becomes partially fragmented after few seconds of not doing anything, Although the internal monitor is not functioning, when i connect an external monitor (with FHD resolution) It becomes fully recognised and functioning. When i connect the external monitor the internal monitor becomes blank. With the external monitor i can confirm that i have acceleration.
Here is a log Boot log.
Here is the config.
Here is a picture of the fragmentation.
Here is a picture when there is an external monitor connected.
