(Background info)
I have Ubuntu 12.04 on my HP 110 netbook and it's working perfectly and configured as I like it. I have to use the 2d desktop though because it's not a powerful system. Since Ubuntu 14.04 doesn't have the 2d desktop, I am experimenting with Lubuntu 14.04
(Question)
When I am running Lubuntu 14.04 in "try Lubuntu without installing it" from a live USB, can I install wifi drivers without messing with my installed Ubuntu OS in any way? I don't want to risk it if there is a chance of messing up my beloved Ubuntu 12.04 installation.
