** Summary changed:

- shutdown button does not reapper even when FUSA applet removed
+ FUSA and multiple X11 displays interaction

** Description changed:

- Binary package hint: fast-user-switch-applet
+ There is an "unexpected interaction" between FUSA behaviour of removing
+ shutdown buttons, and users having multiple X11 displays. Here it is my
+ use case:
  
- Preamble:
- I used to use FUSA in 8.10. Then, when upgrading to 9.04, shutdown button 
disappeared from "System" menu, so I decided to remove FUSA. The first time I 
removed FUSA from the panel, shutdown button correctly re-appeared in "System" 
menu.
+ I have two displays: 0.0 is the LCD, 0.1 is a CRT TV that I only use to
+ watch films (0.1 is always active, but I keep the CRT TV shut down most
+ of the time). Both of them used to have the FUSA applet when I was using
+ 8.10 (it was added by default, I didn't add them explicitly).
  
- Problem:
- Now, every time I login, neither the FUSA applet nor the shutdown button in 
"System" menu are present. (!!!) There is apparently no way to shutdown the 
system, or to logout. The only way I have to get shutdown button in "System" 
menu again, is to add and remove FUSA from the panel. After this, the "Systme" 
menu buttons are present again.
+ When upgrading from 8.10 to 9.04 I discovered that the shutdown buttons
+ in System menu disappeared, because of FUSA. Since I didn't like this, I
+ decided to remove FUSA and got my buttons back in the System menu. I
+ only removed the FUSA applet from panel 0.0 (forgetting I had FUSA on
+ 0.1 too). The button re-appeared -- even if FUSA was present on display
+ 0.1, and I could logout.
+ 
+ However, every time I login now, FUSA is not present on display 0.0, but
+ shutdown buttons in System menu are neither, because of the FUSA applet
+ in display 0.1. The result is that display 0.0 is in an inconsistent
+ state: no FUSA, no shutdown buttons.
+ 
+ Of course, removing FUSA from display 0.1 (or adding/removing FUSA from
+ display 0.0) too solves the issue. Nevertheless, I deem this quite a
+ design error.
+ 
+ I see two solutions to this problem: 1) FUSA should be "display independent" 
(or "system wide") as menus are; or
+ 2) meus should be display dependent (which I don't like)
+ 
+ Anyway, the real problem I see, is that we are coupling menus and
+ applets, which is very counter intuitive.
