I successfully installed the gnome 3 gnome-shell from the launchpad ppa on my fully updated Natty test system. However, nothing I tried could get it to actually run.

If I selected it in the startup options, I got a plain light blue screen with absolutely nothing on it.

If I tried to start it using "gnome-shell --replace", I got:

gnome-shell --replace &

[2] 3251 tim@nattytest:/usr/lib$ Traceback (most recent call last): File "/usr/bin/gnome-shell", line 705, in normal_exit = run_shell() File "/usr/bin/gnome-shell", line 293, in run_shell if shell is None: UnboundLocalError: local variable 'shell' referenced before assignment /usr/bin/compiz (core) - Error: Screen 0 on display ":0.0" already has a window manager; try using the --replace option to replace the current window manager.

[2]+ Exit 1 gnome-shell --replace

I also tried preceding that with metacity --replace, as suggested at ubuntuforums.com. But, I got the same failure.

I also linked /usr/lib/libmozjs.so to /usr/lib/xulrunner-2.0b12/libmozjs.so, which did not help either. No matter what I try, I get the same error messages.

Thanks.
