I wonder if the reason is simply that we are not using the same python version as Ubuntu ...
Ideas anyone?

Ok. Fixed now using python2, seems to be working:

Hello there, i'm also using arch on a Optimus laptop and i've try many solution but none of theme fully work (some applications works fine some other don't). I've installed a ubuntu on a different HDD to test the nvidia-prime proprietary and it works just fine, all applications use the nvidia card. So I'm happy to see that some of you are porting this to arch. But when I test it it doesn't work:
$ sudo prime-select nvidia
Info: the current GL alternatives in use are: [None, None]
Info: the current EGL alternatives in use are: [None, None]
Error: the installed packages do not support PRIME
Error: nvidia mode can't be enable
If anyone have an idea on how to get ride of this I would be really thanksfull!

Fork from Fedora-prime to be multi-distros. Works nicely... now. :s
