Difference Between Gnome Installation and Gnome Installed Later

view story

http://forums.fedoraforum.org – This question is primarily for my own education. I first tried to install Fedora 18 choosing the Gnome desktop option, but the desktop was unusable after logging in (the appearance was of a font with mostly blank characters and occasional colored backgrounds). Later, I was successful at an install with the LXDE desktop choice. I then installed Gnome on that system (yum groupinstall "GNOME Desktop") and found that it worked perfectly. There are some obvious differences; for example, I now log in to Gnome using LXDE's login manager, which is completely different from that for Gnome (HowTos)
