Bug#758217: xserver-xorg-video-nouveau: Nvidia card no more listed in 'xrandr --listproviders' on Optimus laptop

[Marco Mattiolo <marco.mattiolo@hotmail.it>]

Sorry for the spam: obviously I got, only after closing bug, idea of 
googling without restricting to nvidia cards.

So found [1], which looks pretty similar, except it's a radeon-related bug.
Also, reporter suggests restarting Xorg gets his Radeon discrete card to 
be discovered by 'xrandr --listproviders',
which I just tested doing the same on my system.
So I'm now able to use DRI_PRIME with nouveau driver on my setup! :)

Hereby, I reopen the bug, which is now about the Nvidia card not being 
recognised by Xorg on first start:
feel free to reassign it to xorg-server, if you think it appropriate...

Cheers
Marco
