Yesterday, I upgraded my Ubuntu 11.04 tot 11.10. After some trouble I managed to remove Unity and I installed GDM & gnome-shell as a replacement. I configured it a bit: installed some extensions, changed some themes, etc...
My question now is: What will happen if I upgrade my 11.10 to 12.04 (and afterwards to 12.10)? Will Unity get reinstalled and if so: will I lose all my GDM modifications?
Thanks in advance!
