So, here i am with my (first world) problems....
I'm standing here on stable xfce 5.12 (+ task-mate-desktop) with my xmg a507 notebook and nvidia's properitary nvidia-driver:

so, my problem is that i can't start nvidia's GUI... /usr/bin/nvidia-settings - i just get:
Quote$ nvidia-settings
ERROR: Unable to load info from any available system
After blowing my mind and stressing my laptop for more than one day, i'm still not sure which GPU is actually in use because i get different statements and prime-select is not availible (only primerun&optirun).... Also i have no /etc/X11/xorg.conf ... after generating one with nvidia-xconfig lightdm broke down... so deleted xorg.conf and dpkg-reconfigure etc....
So i installed gdm3.... and gnome... and mate... that's not the problem...
What i guess is that bumblebee has no access to nvidia's modules....

although I suspect the problem is with nvidia, I'd be happy if anybody has any ideas.... 8)
