Michael, this sounds really bad. I'm sure it is debuggable ;)
- startx only works as root as the SUID bit isn't set any more.
- I suspect he culprit to be gdm, you may want to edit 
  /etc/sysconfig/displaymanager to select a different one - try and start with
  xdm - even though it may not have a look which is very appealing to you.
  However, before you do so, you may want to collect the Xorg.0.log and
  Xorg.0.log.old files, open a new bug(*) and attach them.
- It may be gone with Leap, however if you will stay with 13.2 for a while I'd
  rather debug this with you than with someone with little experience ;)

(*) you may have done so already and I haven't seen it if so please kindly
point me to it.
