Please provide complete details in your profile/signature (pointer over your name in upper right - drop down menu select Settings and Edit Profile from options in left pane of Settings menu.)

System: manufacturer/model
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution

For example, typical Ivy laptop:
System: HP ProBook 4540s
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768

Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx). For a laptop, these details are important and affect critical installation procedures.

Read post #122 carefully. Must be in your profile/signature.

Power management is implemented incorrectly, see: http://www.tonymacx86.com/mavericks...nagement-sandy-bridge-ivy-bridge-laptops.html

Try setting resolution in the bootloader:
"Graphics Mode"=1366x768x32

No difference i have tried that with both chimera and clover , the same graphics problem remains

Tried what? Power management? If you 'tried it', you didn't do it correctly. Ioreg indicates several problems with power management.

 

[ra91111]

tried this : Try setting resolution in the bootloader:
"Graphics Mode"=1366x768x32


so you are suggesting that the graphics flickering problem i described above is related to the power management or something else?

Not that the syntax shown is if you type it. In org.chameleon.Boot.plist looks like:

<key>Graphics Mode</key>
<string>1366x768x32</string>

so you are suggesting that the graphics flickering problem i described above is related to the power management or something else?

Could be. It could also be DSDT issue, EDID not being picked up correctly, problems with your install procedures (eg. too much substitution of patched kexts, etc), and a host of other things.

My motto: Do everything correctly before testing specifics.
