[SOLVED] - [Gnome 3] GDM error dialog "failed to start session GNOME"

Question

Hi,
Just installed Gnome 3 from testing.
First boot crashed, but that was a missing library for splashy, so removed splash from my grub boot line.
Now the system boots to GDM. I can start my Xfce session without any issues, but if I select Gnome, I get a dialog "Failed to start session GNOME".
Following is my GDM greeter log:
gnome-session[2208]: WARNING: Failed to start app: Unable to start application: Failed to execute child process "/usr/lib/at-spi/at-spi-registryd" (No such file or directory)

All help greatly appreciated.

Answer 1

I just remembered to do that.....
Think I have found my problem.
The Arch Wiki for Gnome 3 has the line for installing to a new system
# pacman -Syu testing/gnome
This installs gnome 3, but does not include gnome-shell or gnome-panel
Just installing them now. Will report back shortly.
Maybe the Wiki should be updated to reflect this, or the package testing/gnome updated to depend on gnome-shell and gnome-panel.
Cheers.
