I've installed Ubunto+LXDE. It works fine (many thanks for all the guides and help). At the end of my work I close all apps and press Logout. First time the Icon is red, then grenn but LXDE or Ubuntu never wil be closed.
To close Ubunto I minimize CHroot and close it like all other HP Apps by moving over the top.
I think to close a OS this is not a good option. How Can I close LXDE+Ubuntu chroot ?
