I have ubuntu 12.04 and I have switchable graphics.

Intel HD Graphics 4000 and AMD RADEON HD 8730M

The problem is this, when I have discrete graphics enabled (AMD) everything works fine, but the heat goes up even tho I have the prop drivers. And when I switch to Embeded (Intel) nothing that uses 3D stuff works, by running a few games I got the error/info that something is wrong with xorg server. Any ideas?

Thanks in advance.
