starting GDM gets me an xterm, not the Gnome desktop

[Bob Middaugh]

Hi everyone,
I installed 6.2 and chose X-Developer for the distribution.  After the install, but still in sysinstall, chose gnome from the packages.  When gnome finished installing, I rebooted.  I did startx as root and got the xterm, but when I typed gdm from the prompt, nothing happened.  

So, I went back into sysinstall and chose gdm(usually it gets installed as a D).  After the gdm install, I did startx as root, got the xterm, typed gdm, got the gdm dialog box and logged in.  Instead of getting the gnome desktop, I got an xterm session.  This has never happened to me before, and I know I've been doing it this way since 6.1 for sure, but probably 6.0 as well.  

Does anyone have any insight as to why I'm not getting the gnome desktop?

Thanks,
Bob
