Bug Description

Nvidia Settings asks sudo password to change between Nvidia and Intel card.

It should be something trivial, no need to password here... (hey, bumblebee does this without password, and by the way, without something like a button "Performance x Power Saving")

Bumblebee doesn't require a password because it doesn't switch between GPUs. Bbswitch does, and doing so requires root privileges.

Ok, bbswitch does, but it is unseen by end user (at least, when you use bumblebee, for example).

Is this behavior not unfriendly for user perspective? (and I'm not talking about logout and login after the change...)

Alberto Milone (albertomilone) wrote :

Apparently Bumblebee now uses a daemon which I assume runs with root privileges, hence it doesn't need to request the password. We can probably work around that with policykit.

Why is it marked as invalid? I'm having problem with this right now...

I can use bumblebee, but i can't anymore switch to nvidia card with this "button solution". And no errors messages...
