KDE not Starting

This morning I started my SuSE 9.1/KDE 3.2 box and it goes through the boot process but leaves me at the 'linux login:' prompt in a text console when it should have started KDE. I logged in a root and did an 'init 5' and it put several things up on the screen, displayed the nvidia splash screen and returned to the text console. What do I need to do to get KDE running again? I'm not seeing any errors during the boot that would lead me to the problem. -- Bill Lugg Milstar Software Support Peterson AFB, CO
