Forwarded to correct bug report in plan text=> bug 393041
Today I installed a from scratch etch Debian with all current packages for KDE. After a brief time, KDE stopped accepting my root password for simple tasks such as setting date and time from control center. This bug also prevents running some other applications such as synaptic. KPackage is unaffected for some reason. Until this is fixed, a work around is to add yourself to the sudoers file. This will allow running various control center apps from the command line like: #sudo kcmshell kde-clock.desktop If your shell refuses to use the current display, try #xhost + This problem has been confirmed by a few persons now in #debian-kde
