No "session-change" icon after logout visible

[Thomas Bechtold]

I can not see the icon to change the session (eg from ubuntu to gnome) when i logout.
When i select a different user and then select my user again, the icon is visible.

Steps to reproduce:
1) login (currently i use the gnome-shell)
2) logout
3) see that there is no icon to change the session

No the steps to be able to change the session
4) select a different user
5) select your user again
6) now the icon is visible

Possibly dupe of bug 918657

Got that issue on my Ubuntu i386 system:
- unity-greeter is installed by default as expected
- but i'm using gnome-shell which install gdm's packages

- lightdm is choosen in my case, but switching to gdm does resolve that issue.

So it seems that the ancient unity-greeter bug is back again.

Other sad effects:
- if unity-greeter is uninstalled (so using lightdm-greeter-gtk 1.6.1-0ubuntu2) then 'nouveau" is loaded in low graphic mode
- got garbage colors for the lightdm screen
