    X Error: BadDevice, invalid or uninitialized input device 169

    Hi,

    I get the above error every time I give a command in the console. I read the following article:

    http://kubuntuforums.net/forums/inde...64.0;topicseen


    I made all the changes, but my xorg.conf file is slightly different. (I only quote the modified part here):

    #Section "InputDevice"
    # Driver "wacom"
    # Identifier "stylus"
    # Option "Device" "/dev/input/wacom"
    # Option "Type" "stylus"
    # Option "ForceDevice" "ISDV4" # Tablet PC ONLY
    #EndSection

    #Section "InputDevice"
    # Driver "wacom"
    # Identifier "eraser"
    # Option "Device" "/dev/input/wacom"
    # Option "Type" "eraser"
    # Option "ForceDevice" "ISDV4" # Tablet PC ONLY
    #EndSection

    #Section "InputDevice"
    # Driver "wacom"
    # Identifier "cursor"
    # Option "Device" "/dev/input/wacom"
    # Option "Type" "cursor"
    # Option "ForceDevice" "ISDV4" # Tablet PC ONLY
    #EndSection

    Section "ServerLayout"
    Identifier "Default Layout"
    Screen "Default Screen"
    InputDevice "Generic Keyboard"
    InputDevice "Configured Mouse"
    # InputDevice "stylus" "SendCoreEvents"
    # InputDevice "cursor" "SendCoreEvents"
    # InputDevice "eraser" "SendCoreEvents"
    EndSection

    I rebooted after editing the file, but now get other errors. Is there something I did wrong?

          It's supposed to be kdesu kwrite for KDE (read: GUI) apps; sudo belongs to console apps only (- as has been discussed in these forums in all details back and forth :P).

            I'm DUMB, DUMB, DUMB!

            I'm new to Ubuntu and mixed up commands from suse that I'm used to.

            Could you please give me a link to a clear, well written article about the difefrencess sudo, su kdesu?

            Sorry I bothered you with this.....

              I don't know of any articles on it. I usually just type up the explanation when it's required.

              "sudo" is for commands, "kdesu" is for apps. "su" you'll probably never need, it changes to another user.

              You could also try reading the man pages ("man sudo", "man kdesu", and "man su").

                There is RootSudo
                https://help.ubuntu.com/community/RootSudo

                By default, the root account is locked in Ubuntu. This means you cannot login as root or use su. Instead, the installer will setup sudo to allow the user that is created during install to run all administrative commands.

                This means that in the terminal you can use sudo for commands that require root privileges. All programs in the menu will use a graphical sudo to prompt for a password. When sudo asks for a password, it needs YOUR USER Password; this means that a root password is not needed.
                and about kdesu..

                Avoid sudo to start graphical programs. You should use gksudo or kdesu to run such programs.
                and lot of other things.
