Graphics problem

[Mechislav]

Hey!
I have successfully installed Yosemite on my laptop but have a floating problem with graphics: sometimes when the OS boots, it flashes white, then shows the desktop, but the resolution is low, it cannot be changed and the graphics are laggy.
I have tried GraphicsEnabler=Yes and No, but none of these worked.
There is Intel HD Graphics and nVidia 820 on my laptop.
I am using chameleon bootloader and my plist is:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

Chameleon does not support IGPEnabler.

If you want to use Chimera flags, install Chimera.

I am very sorry, it turns out my bootloader is chimera, don't know, why I have written it is Chameleon

Correct flags for Chimera depend on your screen resolution, which you have not specified.

My screen resolution is 1366x768

Thank you.
What are the possible ways of fixing that?

Edit the plist to fix whatever problem you caused in it.
