Getting on the SuSE 9.1 menu

[Dennis J. Tuchler]

I have installed XFCE4 on three computers using SuSE Linux and presenting a 
KDE login screen.  On two of these, I have no problem with selecting XFCE.  
On the third,  after installing XFCE4 under SuSE 9.1, I cannot get XFCE on 
the log-on menu.  As I recall, this question was asked before but I cannot 
find a record of the answer.  Please help.

Thanks
