I'm using Gnome now and want to install XFCE. Nothing complicated but just curious - do all applications, installed previously on Gnome will be also removed or they would work on XFCE properly after installing XFCE and removing Gnome ?
OS: Linux Mint 7
You might lose functionality in any desktop widgets that were using Gnome, but in general, all of your application using GTK should not in any way be affected by what desktop environment you are using.
At least under Ubuntu, I am fairly sure that uninstalling Gnome should only affect the desktop environment, it should not remove any applications that are not explicitly tied to the Gnome desktop.
