device is unsuitable for gl - disabling OpenGL

[ksc91u]

My device is Lenovo T430s with i5 3230m, Intel HD 4000

 

I have patched my DSDT, and set IGPEnabler = Yes and IGPlatformID = 01660004 in org.chameleon.Boot.plist .

 

But in /var/log/system.log always shows 

 

WindowServer[250]: update_gl_acceleration: device (0x7fc919e152d0) is unsuitable for gl - disabling OpenGL

WindowServer[250]: initialize_display_context: dev counts are zero (0, 0) - disabling OpenGL

 

I can boot normally, but no QE/CI. 

 

kextstat shows AppleIntelHD4000Graphics.kext and AppleGraphicsPowerManagement.kext does not load automatically.

 

Only AppleIntelFramebufferCapri.kext loads.

 

My _DSM Method in IGPU is like

Can someone help please?

Within the platform search using the arguments hd4000 agpm I have got this: http://vhttp://www.insanelymac.com/forum/index.php?app=core&module=search&section=search&do=search&fromsearch=1 You have just to read the matches and try methods.

 

Have fun.

OK, I found a temporary way to work.

 

Boot to single user mode.

 

kextload AppleGraphicsPowerManagement.kext/

kextload AppleIntelHD4000Graphics.kext

kextload AppleIntelFramebufferCapri.kext/ 

 

and 

 

launchctl bootstrap -S System

 

 

Full QE/CI.
