I'm using a Zenbook with a hybrid Intel/Nvidia graphic card solution. I tried it with Bumblebee and Nouveau a long time ago and then didn't use the Nvidia card for a long time. Now I tried it again and stumbled upon PRIME. $xrandr --listproviders didn't show me the Nvidia card but #modprobe nouveau did the trick and it worked. Now I tried switching to the nivdia driver to compare the gaming performance but I don't see the card in $xrandr --listproviders and #modprobe nvidia doesn't do the trick anymore.
I don't have a (deprecated xorg.conf file or xorg.conf.d/ config file which according to the wiki isn't required anymore.
Do you have any suggestions what might be the reason? Or what other things to check?

Make sure you follow this page, since it is an optimus system. I just finished setting my system up the same way, after jumpng from Nouveau.
https://wiki.archlinux.org/index.php/NVIDIA_Optimus
It says you don't need the old stuff in your config files, but then it say you need to add this to your xorg.conf...
Section "Module"
Load "modesetting"
EndSection
Section "Device"
Identifier "nvidia"
Driver "nvidia"
BusID "1:0:0"
Option "AllowEmptyInitialConfiguration"
EndSection
I went ahead and put your BusID in there.
My "dmesg | grep nvidia" displays one line that yours does not, about enabling the device...
nvidia 0000:01:00.0: enabling device (0004 -> 0007)

Thanks for your detailed help! I followed the article and added the sections to my xorg.conf and .xinitrc. However I get a black screen when booting. If I switch to another console, login as normal user and then execute $startx it works surprisingly. But the provider list of xrandr looks weird to me then with one provider being "NIVIDIA-0" and one "modesetting". I do get some output from xorg.log and dmesg but I can't really judge it.

Yeah, I still don't see the line in your dmesg output about enabling the device. That is probably a problem.
Your xrandr --listproviders looks just like mine, with those 2 entries (NVIDIA-0 and modesetting), however it shows that your NVIDIA has [ Source Output crtcs: 0 ]. That is probably a problem, as well.
Do you have an "Enable Optimus" option in your bios? Or any other options pertaining to the video card settings? Check and make sure you are not telling the system not to use the card.

Thanks for your reply!
The problem was that I didn't pay attention to my Loginmanager (sorry my fault). So it didn't run the xrandr-commands before the start of x. That explains why it worked for startx. I switched to LightDM (since Slim is unmaintained anyway) and configured it correctly which solved the problem. In the end I switched to Bumblebee again now to be able to switch cards which seems to work fine.
