Enable full gnome instead of gnome fallback :)
If your graphics card doesn't support 3d-acceleration, Gnome 3 automatically runs the fallback-mode (Kali's Default mode) So instead of the "pretty" Gnome-Shell and Mutter you get the old Metacity and Gnome-panel.
To get your current value,open a terminal and run:
gsettings get org.gnome.desktop.session session-name
To change it run:
dbus-launch gsettings set org.gnome.desktop.session session-name 'gnome'
Then reboot and login.
Took me ages to find this out :)
Gnome fall-back to gnome failed to load.
I tried i as you told setting the session-name .
But still it is failed to laod the gnome 3, it is displaying some error liked failed to laod the gnome 3 because you driver is not supporting 3D acceleration .
When i checked the session name it is showing 'gnome' and it is using guallium in fallback mode.
by the way i installed new version of kali 1.1.0 and i am using Core i5 with intel graphics 4400.
please help me thank you.
