I have installed Suse Linux 10 and opted for KDE during installation. How can I try out the Gnome environment? Do I have to go back and re-install opting for Gnome or can I switch backwards and forwards between the two environments without hassling with installation again? When I log off and logon again, the options available currently are FVWM, KDE, TWM, WindowMaker and Failsafe. I'm not sure what these different options mean but none of them appears to be Gnome.
