@Remten: unfortunately, we only modify the main lightdm configuration file. If you install other Ubuntu flavours after installing nvidia-prime, it might not work.
You can try the following steps:
1) Remove the xubuntu settings package (also pay attention to the other packages that this removes):

You can try the following steps:
1) Remove the xubuntu settings package (also pay attention to the other packages that this removes):
sudo apt-get --purge remove xubuntu- default- settings
2) Reinstall xubuntu- default- settings:
sudo apt-get install xubuntu- default- settings
3) Reinstall any packages that were removed when you uninstalled xubuntu- default- settings
4) Make sure that the alternative is set to Xubuntu:
sudo update-alternatives --config lightdm- gtk-greeter- config- derivative
(and select the alternative for Xubuntu)
5) Finally reinstall nvidia-prime:
sudo apt-get install --reinstall nvidia-prime
