I'm an elder non-techie Mac-to-Linux convert trying to play the linux tech game by ear, so please be gentle! :)

I am running XFCE Ubuntu 12.04 totally on a 8-gig flash drive and it's fantastic. I am starting to run into potential space issues (down to 1.0 gig free from 1.9 gigs since being installed last summer), most likely because of growing Thunderbird mail files, and this prompted my question. I just installed lightDM on my system because I want the ability to switch users in XFCE if I follow instructions on another blog. They advised using LightDM instead of GDM because LightDM doesn't download Gnome libraries. That's great since I need the space, but my question is how can I tell whether I don't already have Gnome libraries installed from other updates and such? And can I minimize having any Gnome libraries? The method for me to switch users entails creating a "fast-user-switch" file in /usr/local/bin; is there any easier way? One last thing so I din't have topen another needless thread; while experimenting I somehow lost the share folder in one of my accounts. Is there any way to get a share folder back?

Thanks for any tips!

I have two Ubuntu systems and in the course of changing configurations something has become muddled. I have disabled Unity in favor of gnome shell, the older style display of the desktop.
