Sabayon install many desktops for the user may choose in the sessions...
i feel this!. i use sabayon mainly because this , because i like all graphical ambients.
Mandriva also have this feature. mandriva Free.
but if your sabayon installed GNOME, only if you wanted, it install KDE together, because KDE was marked to be installed.
XFCE, Fluxbox etc... LXDE, were installed as default.
if you want only GNOME, the more easy manner, in your installed system, ie to open spritz (the graphical package installer, the sabayon equivalent of synaptics) an Blue Star icon in desktop,
and choosing all the KDE packages, and all of xfce packages, flux box etc... marking these packages for uninstall...
etc... and remove then.
if you want only a sabayon installation, with only GNOME, you may try the Lite MCE, because is the sabayon only with gnome!,
and not the full 4.0.r1. you choosed the full Sabayon, with many graphical ambients!
