What laptop model, CPU and GPU do you have exactly? It could be that the default power management method does not work properly, which is true in my case (MSI GP62 6QF, i7-6700HQ, GTX 960M), so only the on-demand mode works. I was able to fix the performance mode by installing the bbswitch-dkms package, then I did a couple of other things to get the Nvidia GPU to turn off properly in Intel mode (add "bbswitch" to /etc/modules and "options bbswitch load_state=0" to a new file in /etc/modprobe.d/).
