[CentOS] How to find available groups for installation via yum ?

Hi All,

Short description of the problem: - I would like to install the complete 'xfce' desktop on CentOS5.x

I've tried: yum groupinstall xfce yum groupinstall xfce4 yum groupinstall xfce* yum groupinstall xfce4* yum groupinstall xfce4.2 yum groupinstall xfce4.1 yum groupinstall xfce4.3 yum groupinstall xfce4.4 yum groupinstall xfce4.4.2 .... etc etc ... nothing worked

then I've started googling the net and .... ____finally____ I found the magic combination. One very merciful soul posted the golden combination.

yum groupinstall "XFCE-4.4"

This did the trick. God bless him/her and all his relatives. He/She deserved it.

question: Is there a way to check which packages are available for the installation as a 'group' using yum ?

TIA

Igor
