Hi all,
I'm running OS X 10.10 on my Lenovo Y510P (which has mobile Intel HD4600) and I have a problem regarding display sleep. Any action that set display to sleep (via hot corners for example) results in these problems when display return on:
1. Restart is not functioning (system halt with display off but fan and light are on). Shutdown works fine though.
2. Graphics are partially distorted like reverting to 16-bit colors and it's very noticable in launchpad and while playing videos. Only fixed by turning system off/on again. (Screenshoot here: http://s14.postimg.org/r5n874vup/IMAG0369.jpg)
It's not about system sleep/wake because this works fine. However, the display sleep issue affects the system sleep/wake since it's part of the process. Please help me to figure out how to solve these (just hints no need to patch anything for me, I need to understand).
Currently I've few edits on my DSDT. Graphics is patched through Clover (in addition to patching OpenCL). Attached is my clean ACPI, my currently modefied ACPI, and IOReg zip.
PS: I know Nvidia is enabled but the same problem exist even with it disabled.
Regards,
Ahmed
