PCLinuxOS is distributed with different Desktop editions. I've installed one and thinking about switching to another one. Obviously complete re-installation seems to be an overkill. Probably the switch can be done by changing repositories and doing update. I guess it should be even possible to have more than 1 Desktop installed (ie. Gnome Desktop and XFCE Desktop) and different users could use different one.
So, I'm searching for information on how to do it. Appreciate any advices.
