HOW CAN GNOME and KDE CHANGE EASILY

good night in china,
I install openSuse11.0 from disk successfully during one week. but i want use GNOME or KDE on my mind.what’s road to do it.

or How can i change GNOME AND KDE each other. thanks a lot

install suse dvd/cd , during installation select either gnome or kde as desktop manager ( at this moment in time it does not matter which one you choose) make sure that when you create a user logon dont tick automatic login ( to make it easier for yourself).
towards the end of the installation you are presented with a summary of all things that suse is going to do to your computer.
there is an option called software, click on software and then on the next screen select kde4. press save and complete installation.

once installation is completed you will be presented with logon screen.

select other, towards the bottom of the logon screen you can now choose between kde4 or gnome. type the username of the user you had created and then password and voila.

hope this helps.

Adding to this, I never changed desktop environment. So, if I have both KDE 3.5.x and 4.x installed, and using 3.5 as default, how can I change today to use 4.x and then to change back to 3.5 when I please and back to 4.x etc?

I mean, changing KDEs back and forth with less hustle possible

It could be possible if you are login to kde 3.5
Just open a terminal and run plasma then you will be able to run both in one shot

Sorry, how to run plasma from terminal?
Command was not found, I typed into smart, it just installed themes, so I reckon I have plasma already.

Does it mean kde 4 is not fully installed in your system?

I am using two monitors on one machine with xfce The first monitor is using the xfce desktop and the other I use kde 4 sometimes to play with it from the terminal with that command. In some of the screenshots thread from the previous months I posted a screeny showing plasma running from xfce.

Hmm… seems that it is not… when I tried to add, it woul downgrade some kde4 packages from 4.1.x to 4.0.x, and will uninstall another bunch or so…
maybe I will just forget about this for now.
