    Ubuntu 13.04, Gksu/Gedit command error

    I am trying to execute the following command within Ubuntu 13.04 so to eventually install a Realtek driver rtl8192cu; "gksu gedit /etc/modprobe.d/blacklist.conf". Once I key in the command, a separate password screen appears to which I key in my admin password (the same one as the initial logon password) but it comes back flagged as invalid. I have double checked that I am keying in the correct password but it is flagged invalid. Any suggestions would be appreciated.

    When I keyed in "gksu-properties" command I was then presented with the same pop-up screen asking for my administrative password, which when keyed in came back as invalid. I assume that my administrative password is the same one that I key in for the initial Ubuntu login screen. If yes, I don't know why it is coming back as invalid (I never had this issue with 12.10). Any other suggestions?

    Sounds to me like permission problems?
    Are you on the sudoers list?
    $ sudo cat /etc/sudoers
    you should see your username in the list or a line that permits users within the group of sudoers
    In which case you could do: $ groupadd -f sudo
    Or open users & groups UI and make sure your in the sudo group.
    Or perhaps you need your root password? You might have created this when you installed Ubuntu
    Although in order to preform such a task you need root access first.
    Kinda like the chicken and the egg. But it is possible...

    PS. when I do $ gksu-properties
    a small UI window opens
    "privilege granting preferences"
    Behaviour:
    Authentication Mode: 'su'

    Screen Grabbing:
    Grab Mode: 'enabled'

    Peace!

    If you're getting a password authentication screen when entering the gksu-properties screen , then I would suggest making sure there are no spaces in the phrase.
    If it said gksu -properties, then the program will think that you'd need to run whatever command comes after as root and ask for permission.

    Problem solved. I first had to do the following from Recovery Mode, then selecting "Root" from the menu, and then the following to create a new root account password;

    mount -rw -o remount /

    sudo passwd root

    I thought this was done already when downloading/setting up 13.04 (I did not have to do this in 12.10) but apparently not. Thanks for your help. dc
