Good evening friends i have good news the problem is solved in my setup.I enable HD4000 to work together with my GTX 660 and the problem disappear.
What you don't understand?What are the steps you took to do that?
Or, how does one do that?
What you don't understand?
First go to your bios set IGPU as your primary graphics and shared memory to 64MB.
Finally in your org.chameleon.boot.plist bellow these lines <key>GraphicsEnabler</key>
<string>No</string >
inject
<key>Graphics Mode</key>
<string> 1920x1080x32</string>
<key>device-properties</key>
<string>7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000005006201140000006800640061002d0067006600780000000d0000006f6e626f6172642d31<string>
If you have a 1080p display.If not adjust your current resolution in line 2.
and voila! you have both GPU's working together and this ****ty bug disappear.Good luck!
