bbswitch can't activate discrete card

Hi,

I'm the owner of a Asus UX303LN, and it got a GT840M graphic card. I followed the article about Bumblebee, and tried to run The Binding of Isaac using optirun, but it gloriously failed

simon@cthulhu $ optirun steam steam://rungameid/250900

So I checked the bbswitch status of my card with dmesg

simon@cthulhu $ dmesg | grep bbswitch
[    5.018008] bbswitch: version 0.8
[    5.018013] bbswitch: Found integrated VGA device 0000:00:02.0: \_SB_.PCI0.GFX0
[    5.018018] bbswitch: Found discrete VGA device 0000:03:00.0: \_SB_.PCI0.RP05.PEGP
[    5.018097] bbswitch: detected an Optimus _DSM function
[    5.018153] bbswitch: Succesfully loaded. Discrete card 0000:03:00.0 is on
[    5.019254] bbswitch: disabling discrete graphics

What did I do wrong when I followed the tutorial? And is there a way to interprete the discrete card as a standard graphic card and always use it for every application like xorg?

Thanks in advance

P.S: I check the BIOS, there's nothing about the GPU activation
