GDM3 Duplicates Menus Clocks Workspace Switcher etc.

[Felix Winterhalter <felix@audiofair.de>]

Hey there everyone,

I just installed debian wheezy and I get the following problem with 
gdm3: Every time I login the menu items are added again (to the already 
existing items) and the clock is added and the logout menu is also added 
as is the workspace switcher and the taskbar ... So after 3 logins I now 
have three of every sort ... reinstalling gdm didn't even remove the 
menu entries neither did completely rm -R * ing the home directory

I have no idea what to do anymore

I am using a Dual Screen Setup which I had lots of trouble setting up 
using the free driver for ATI cards so I switched to the proprietary one 
and used the initalize function of aticonfig for two monitors. However 
Gnome shows still only one monitor in its system settings, maybe that 
could be related...

I am very grateful for any idea!

Thanks in Advance,
Felix
