I am running Quantal using the Catalyst 13.3 ATI driver for Intel HD 4000/ATI HD 7670M setup. I can switch between integrated and dedicated GPU with amdconfig --px-igpu or amdconfig --px-dgpu. Upon reboot it's always the dedicated card that is selected, so I have to switch manually again after boot and then restart X. Is there a way to set the integrated GPU to be default? This way I can switch to dedicated graphics when needed (not very often).

You can perhaps try and enter the command amdconfig --px-igpu in this file: /etc/rc.local
