Comment 1 Kevin Kofler 2008-06-26 17:59:45 UTC 
Running KDE apps with su or sudo can lead to X11 access permission problems 
(not sure why sudo works for you and su doesn't), try using kdesu, e.g.:
/usr/libexec/kde4/kdesu dolphin
(I'm not sure why KDE 4 hides kdesu in libexec. :-( It's a nice tool to run 
directly.)
Comment 2 Cepreu 2008-06-26 23:09:51 UTC 
Ok, but with kdesu i also have problems. look at
