I have a laptop running Fedora 16. I am using Gnome 3 as a desktop environment and it works fine. I tend to use vncserver-client a lot. I started vncserver in my Fedora 16 machine and tried to connect to the server from a vncclient to see Gnome 3 in fallback mode.

How do i fix this?

Here is my system profile http://fpaste.org/aHdw/

@kparal: Yes, When i normally login to my system Gnome 3 is fine. When i start a vnc server , i suppose it starts another instance of Xorg at display :1 or :2. When i tried to connect to that vncserver instance, i see Gnome 3 start in fallback mode.

As vnc runs over the network, there are bandwidth constraints that a fully composited desktop might exceed; you could be getting fallback mode by design. I've tried a number of different configurations, like VNC, X forwarding, SPICE - and only seen the full experience on bare metal.

This could be a bug, or it could be the expected behavior for a remote session. I suggest filing a bug against gnome-shell or mutter, the gnome3 window manager; it might be the most effective way to find out for sure.

The GNOME folks are making regular and substantial improvements to gnome3, so watch your updates. There's a fix in the works to allow the 3D desktop to work with software rendering, which could resolve your issue.

In the meantime, try rdesktop and see if it works any better. I expect it will be a better experience, even in fallback mode.

Sorry that there is no real solution in my answer - but I didn't want to leave you thinking that you were doing something wrong. The functionality you are looking for just isn't there.
