change from gnome to kde in 12.3

When I installed 12.3 I chose gnome instead of kde, how can I change to kde now?

zypper in -t pattern kde4

If you want to change from gdm to kdm you can edit /etc/sysconfig with Yast.

You may want to set both these

Thanks for all your help, the world is right again, works great, thanks againā€¦JSM
