[Lilux-help] KDM startup problems

Can anyone give me some advice on how to begin debugging a KDM startup problem? Whenever I turn on my PC, it boots normally, starts X successfully, and then TRIES to start KDM. It hangs just after it changes the curser to a watch, but still leaving the ugly grey X background. If I switch to another VTY, and change the run level to a non graphical level, then change it back again, KDM works perfectly. Likewise, if I do a ps -A and kill the first instance of kdm, it starts up without further problems. After it has successfully started up, I never have any further problems with it. The only changes that I have made to the system is to install the debian version of Grub. I am running SuSE 8.2, but have upgraded kde to 3.2. Mike
