I have also the same problem. With two monitors, I change the monitor positions (left/right) in the nvidia-settings tool (started with sudo) and write it to the X Configuration file (/etc/X11/xorg.conf). The file is changed, but the monitor positions are reset after next reboot.
I wondered why there is only one Monitor section in the xorg.conf file, but the gui of nvidia-settings mentions two monitors (one connected per DVI, one per DP at my Geforce GTX 1060).
I can confirm that the "Package xorg-server was not found " error vanished after installing xserver-xorg-dev, but the following error is still present:
