    Missing mouse and keyboard controls in settings manager

    Using Xubuntu 12.04 and after installing Xfce4, the mouse (and keyboard) control applets are gone from the Settings manager. Also missing is the Xorg/Nvidia applet from the Accessories menu. Being new at this, I am not sure what I did exactly and don't know the terminal commands to check, but I do know that xfwm4 is running and it's one of the startup applications. Thanks in advance.

    Using Xubuntu 12.04 and after installing Xfce4
    Xubuntu includes Xfce, so this is a little confusing. Did you install xfce on top of an Ubuntu installation?
    the mouse (and keyboard) control applets are gone from the Settings manager.
    If you did install Xfce on top of Ubuntu, the keyboard and mouse applets are included in the xfce4-settings package. Was it installed as well?

    Thanks for asking the right questions, since I didn't know where to begin to get "the ball rolling". The installation is pure Xubuntu 12.04 from disk and not an upgrade from Ubuntu. As you pointed out, the above mentioned applets existed in the Settings Manager (and a couple of additional ones as well), in the original install. The applets appeared neatly laid out as opposed to currently being fewer applets which are divided into lined sections.

    I tried to teach myself to make sense of all the various desktop environments and their components, and the differences between Xfce, Gnome, KDE, and installed some components from Gnome and KDE as well. Then, some time ago, I found this link http://www.psychocats.net/ubuntu/purexubuntuprecise and ran the posted commands , as well as to be sure, I reinstalled Xfce 4.10, when the problem of the missing applets appeared.

    I reinstalled Xfce 4.10, when the problem of the missing applets appeared.
    Xubuntu 12.04 included Xfce 4.8. If you've installed 4.10, have either upgraded Xubuntu to a newer release or are you using the 4.10 PPA?

    To check your Xubuntu release, from a terminal window:
    Code:
    cat /etc/lsb-release
    To check to see if you are using the Xfce 4.10 PPA:
    Code:
    apt-cache policy xfce4

    You have the PPA referenced in your system so you must have had it installed at one time? I'm wondering whether it was installed at one time then removed (or components of it removed) by the commands entered earlier.

    What is the result of:
    Code:
    sudo apt-get update
    ...then
    Code:
    sudo apt-get --just-print upgrade

    Prior to this post 'sudo apt-get update' didn't update xfxe4, although I tried several times. I also suspect that at an earlier attempt to restore xfce4, I only managed to re-install some selected features through Synaptic.

    But now - the following happened as I write this from Windows.

    Successfully installed Xfce 4.10 as reported by 'apt-cache policy xfce4', but there was no change to the Settings Manager. So, I logged out, and the login screen provided the options of Xubuntu or Xfce sessions but neither option worked. Either selection keeps returning me to the login screen. I rebooted, and using recovery mode, connected to the network and it downloaded additional files - but to no avail. It still won't get me in. Since this is a standalone desktop, I never logged in and on boot it went directly to the desktop.

    From within recovery mode:

    1. Delete the .Xauthority and .ICEauthority files from your home directory (if they exist):
    Code:
    rm /home/<USER>/.Xauthority
    rm /home/<USER>/.ICEauthority
    ...replace <USER> with your actual userid.

    2. Check that you haven't run out of disk space:
    Code:
    df -h
    3. Delete your cached sessions:
    Code:
    cd /home/<USER>/.cache
    rm -rf sessions
    4. And finally, check the xsessions log file for any error messages that might help identify a cause for the automatic logout (if anything exists, it will be towards the end of the file)
    Code:
    cat /home/<USER>/.xsession-errors
    Then reboot and see if you get to the desktop.

    1. Deleted the .Xauthority and .ICEauthority files - they did exist.
    2. All disks are less than 10% used - it's a new 500GB disk and most of my data is online at Wikipedia, Commons, or Wikisource.
    3. Removed the sessions file.
    4. .xsession-errors listed only one error regarding blutooth. The file was about 20 lines.

    Many thanks. Did as instructed and logged in to the desktop directly, as it was before. I am still missing the keyboard mouse & the additional driver applets. While logged in as root from the recovery console, I managed to get an ugly graphical interface as root. I checked the settings manager, the mouse, keyboard and other additional applets were there.

    Re: Missing mouse and keyboard controls in settings manager

    Log in normally again. Is there any chance you can send a screenshot of your Settings Manager?

    Is xfce4-settings package installed?
    Code:
    apt-cache policy xfce4-settings
    Which applets are installed:
    Code:
    ls /usr/share/applications/xfce-*
    Note: Additional drivers are located at Software Centre -> Software Sources -> Additional Drivers or by running, from a terminal window:
    Code:
    software-properties-gtk
