Rpmfusion nvidia driver is not loaded (Kernel 4.14.11-300)

Question

I have installed rpmfusion nvidia drivers on my FC27/gnome. However after reboot system says "Nvidia kernel modules is not loaded fallback to nouveau"

[root@dmitry]/home/dmitry# uname -a

[root@dmitry]/home/dmitry# lspci |grep -E "VGA|3D" 
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 620 (rev 02)
02:00.0 3D controller: NVIDIA Corporation GM108M [GeForce 940MX] (rev a2)

[root@dmitry]/home/dmitry# ls /lib/modules/4.14.11-300.fc27.x86_64/extra/nvidia  
nvidia-drm.ko  nvidia.ko  nvidia-modeset.ko  nvidia-uvm.ko

as far as I can see Nvidia 940MX is supported

am I missing something?

Be sure nouveau is not loaded:
lsmod | grep nouveau

If it is, switch to the text console (ctrl+alt+f3), login as root, activate runlevel 3:
systemctl isolate runlevel3.target

Remove the nouveau module:
rmmod nouveau

Try loading the nvidia module manually:
modprobe nvidia

Start the X:
startx

Note that NVIDIA + Gnome + Wayland need some tweaking, it's described in the RPM Fusion's Howto/NVIDIA in section Wayland. (There is also a section about nouveau, it may help you find out why your nouveau module was not blacklisted).
If this helps you, the nouveau module is not blacklisted although I thought the drivers from RPM Fusion did that automatically. Go to /etc/modprobe.d/ and try finding a .conf file that could be blacklisting nouveau:
grep nouveau /etc/modprobe.d/*.conf

If there's no such file, create one, let's say /etc/modprobe.d/blacklist-nouveau.conf with just one line
blacklist nouveau

Now you need to rebuild the init ramdrive against your current kernel using dracut:
dracut /boot/initramfs-$(uname -r).img $(uname -r)
