Headless and back again

I have a headless box running SUSE 9 and for various reasons I would like to run it with the full GUI again. The problem is I can't remember how I made it run headless in the first place (I may have just set it in YAST) and I can't figure out how to return it to normal. I suspect early senility. The google gods have failed me on this one. Any help would be appreciated. John Clark shogun@12ftguru.com
