Just upgraded from Debian Squeezy to Wheezy. When I logged in the menus were fancier as I expected with Gnome Display Manager 3.However the issue that occurred was the duplicate UI-elements. The UI-elements such as Applications, Places, the Clock and so forth had two instances each. What I've tried so far:Though it had something to do with me having a two monitor setup so Iran nvidia-settings and reconfigured /etc/X11/xorg.conf.However as I rebooted the UI elements had increased and now therewere three instances. I think this number increases with each reboot...Tried to manually rewrite the xorg.conf by saving in my home folderand then pushing it into `/etc/X11/xorg.confRenaming ~/.gnome2 to ~/gnome2_backupWhy do I get the duplicate menus and is there a way to remove them/make them not appear after each reboot?My xorg.conf file:# nvidia-settings: X configuration file generated by nvidia-settings# nvidia-settings:  version 304.88  (pbuilder@cake)  Wed Apr  3 08:58:25 UTC 2013Section ServerLayout    Identifier     Layout0    Screen      0  Screen0 0 0    Screen      1  Screen1 1920 0    InputDevice    Keyboard0 CoreKeyboard    InputDevice    Mouse0 CorePointer    Option         Xinerama 1EndSectionSection FilesEndSectionSection InputDevice    # generated from default    Identifier     Mouse0    Driver         mouse    Option         Protocol auto    Option         Device /dev/psaux    Option         Emulate3Buttons no    Option         ZAxisMapping 4 5EndSectionSection InputDevice    # generated from default    Identifier     Keyboard0    Driver         kbdEndSectionSection Monitor    # HorizSync source: edid, VertRefresh source: edid    Identifier     Monitor0    VendorName     Unknown    ModelName      DELL S2740L    HorizSync       30.0 - 83.0    VertRefresh     56.0 - 76.0    Option         DPMSEndSectionSection Monitor    # HorizSync source: edid, VertRefresh source: edid    Identifier     Monitor1    VendorName     Unknown    ModelName      Samsung SMBX2440    HorizSync       30.0 - 81.0    VertRefresh     56.0 - 75.0    Option         DPMSEndSectionSection Device    Identifier     Device0    Driver         nvidia    VendorName     NVIDIA Corporation    BoardName      GeForce GT 430    BusID          PCI:1:0:0    Screen          0EndSectionSection Device    Identifier     Device1    Driver         nvidia    VendorName     NVIDIA Corporation    BoardName      GeForce GT 430    BusID          PCI:1:0:0    Screen          1EndSectionSection Screen    Identifier     Screen0    Device         Device0    Monitor        Monitor0    DefaultDepth    24    Option         Stereo 0    Option         metamodes DFP: nvidia-auto-select +0+0    SubSection     Display        Depth       24    EndSubSectionEndSectionSection Screen    Identifier     Screen1    Device         Device1    Monitor        Monitor1    DefaultDepth    24    Option         Stereo 0    Option         nvidiaXineramaInfoOrder CRT-1    Option         metamodes CRT: nvidia-auto-select +0+0    SubSection     Display        Depth       24    EndSubSectionEndSectionSection Extensions    Option         Composite DisableEndSection
Gnome 3 UI menus are duplicated

It was some spooky settings or cached data from Gnome 2 that was messing with the interface. I saved the important files to an external drive and emptied the home folder, (including .*-files).
