sux not working after kde update

Hi all, after an upgrade of KDE to version 3.4 via Yast the "sux" script seems broken. The typical error looks like that: micha@Moehre:~> sux Password: Moehre:/home/micha # xeyes Xlib: connection to ":0.0" refused by server Xlib: Protocol not supported by server Error: Can't open display: :0.0 An "xhost +" remedies this problem, but the purpose of the sux script is to avoid disabling acces control, I suppose. I'm using Suse 9.1. After the update I cleaned up /tmp and ran the genkdmconfig script. Anybody has a similar problem and knows how to solve it?
