Well...
I've installed NX for a personal test.
Remark : It is a pity to load W$ for installing Nx but I don't know how to do from Linux or Xubuntu to install on a USB stick.
Anyway... If you install on the HDD, DO NOT perform any
Code:
sudo apt-get dist-upgrade
.
In this case, you switch to Lubuntu 15.04 but it does'nt boot and you have to reinstall a fresh version of Nx...
