Hi folks,
Tks for your advice.
Before running rpm -Uvh /mnt/cdrom/Fedora/RPMS/gdm-2* I have following discovery;
On gdmsetup Install new theme -> Filesystem /usr/share/gdm/themes
Selected either circle/happy gnome/happygonome-list
Exited and logout/restarted PC
Still only RH login screen displayed. I could not recall where I have to activate "gdm" otherwise it would work even existing on the OS
TIA
