I've been at this for a while, and it's pretty frustrating. I wanted to try xcfe
yum groupinstall xcfe
These all worked fine - but xcfe won't start. I keep getting back to GNOME.
I've added "exec xfce4-session" to the .xinitrc
the .Xclients-default has WM="startxfce4"
I've rebooted, restarted X, etc.
I don't know if gdm is overriding everything, but there's also no good way I can find to configure gdm. The gconf-editor (looks like regedit) doesn't help much configuring the greeter screen. I remember there used to be a "Sessions" option on gdm, but it's gone now in F9.
If I missed anything, please let me know.
