Can not start GUI

Hi all, I am new to Linux, I have installed openSUSE 10.3 as a virtual machine using Sun xVM VirtualBox on a Vista as a hosting system.
My problem is that I can not start GUI interface for openSUSE, I just see the command line with the words “Welcome to openSUSE 10.3 (i586) - Kernel (tty1).” “linux-… login:”, I choose KDE while installation.
Any Help Please.
Thanks for Concern.

Have you installed the vbox additions? That is necessary to get a guest VM fully working. Also, unless you are experienced, it is advisable to install KDE 3.5.9 rather than KDE 4. You can add KDE 4 later if you wish.
