"Most laptops (and I guess yours to) have the feature to switch between the internal graphics (energy saving) for normal use and the stronger graphic card (energy consuming but powerfull) when you are playing games or doing graphic intensive work.

This works good under windows, but this mac distribution has problems because your computer switches between the 2 graphic cards.

Mac os supports a certain amount of hardware which use internal graphics and graphic card switching.

But laptops like yours are not supported to switch between the cards. I know a lot about this because I had the same issue with my previous laptop, and I looked on every forum searching for the answer."

 

The only solution is to shut off the graphic switching (called Optimus technology with Nvidia cards), or to use a strongly modified kext file.

Try to go in your bios, and if there is an option to disable optimus technology/disable internal graphics, change that.

I had the same problems with my previous laptop, but was not able to fix it because I couldnt disable optimus technology.

Hopefully somebody else on this forum has a fix for this or hopefully the next release will support this.

I'm using fresh niresh mavericks installation, by default the HD3000 detects as primary GPU, when I checked the system info, i was amazed that the Nvidia Geforce 620M was detected, I wonder if this can be set as default, i tried PCIRootUID=1 nvda_drv=1 GE=No and as usual it doesnt works.
