Normal user cannot start KDE - root can
I've just installed Debian Testing (sarge) / KDE 3.1.4 and I've the following problem. I can start / login to KDE as root. However if I want to login as a normal user the screen goes black and after a few seconds the login screen shows again. If I want to startx from the console it returns startx - command unknown. The xsession-errors says:
/etc/kde3/kdm/Xsession: line 7: xrdb: command not found
I think this might have something to do with user rights but I've no clue how / which / where rights to set.
Could anyone point me in the right direction - I'm lost.
