Yes, I tried to start it with startkde. Why is that wrong? (I'm not arguing with you, I just want to learn)

I have done absolutely no configuration at all yet. Just installed Suse, and configured for Belgian keyboards and Vesa resolution 1024x768@75Hz. That's it.

Ok, so I've tried startx now, it also doesn't work. This is the error message. (is there any way I can cut and past this? - I now have to type everything which is pretty annoying)
