    Default Encrypted LVM LUKS and login screen

    Hi. I recently installed OpenSUSE 11.4 64 bit with GNOME yesterday and everything is going fantastic. I like it much better than Ubuntu 10.10 64 bit Maverick Meerkat because it is much more stable, reliable, and dependable. I own a heavily modified ASUS N61JV-X2 notebook PC.

    I installed OpenSUSE using the LVM based method and LUKS encryption. When I turn on the power to my notebook PC, it asks me for my password to decrypt my Intel 2nd Generation 160.00 GB Solid State Drive. I expected this behavior.

    However, I never get to see the OpenSUSE login screen. After I type in my password to decrypt my SSD, it loads up the desktop immediately.

    How do I configure my OpenSUSE so that I can see the login screen so that I can select my standard user profile and enter the user password to login?

    Please reply with step by step instructions. Thank you.

    Try

    Personal Settings -> Login Screen -> Convenience tab.

    Uncheck Enable Passwordless Logins.

    You have selected automatic login.
    Reverse it, login manager, control center.

    I do not see the login manager in the control center. I do not see personal settings, login screen, convenience tab either.

    What do I need to do to solve this problem?

    I am using OpenSUSE 11.4 64 bit with GNOME.

    I also became root and typed in gdmsetup, but it is an unrecognized command. What do I need to do to solve this automatic login problem?

    Use Yast.

    System --> /etc/sysconfig Editor --> Desktop --> Display Manager -> DISPLAYMANAGER_AUTOLOGIN

    Change to the default setting (should be blank). Save the changes. Reboot to test whether it worked.

    The other respondents were telling you what to do from within KDE. I also use KDE, and I think Yast looks a bit different for Gnome users, but it is likely that you can find the right setting.

    Thank you. It worked. I can now see my regular user profile, select it, put in my user password, and login.

    You have found the way, here goes another:

    Edit "/etc/sysconfig/displaymanager":

    ## Type: string
    ## Default:
    #
    # define the user whom should get logged in without request
    #
    DISPLAYMANAGER_AUTOLOGIN=""

    In a unrelated issue your awsome Asus laptop does have a NVIDIA Optimus system.
    Did you have any problems with this during install?

    How do you control what graphics card is used by OpenSuSE ?

    I did not install the proprietary nVIDIA binary video graphics drivers for my nVIDIA GeForce GT 325M GPU in OpenSUSE 11.4 64 bit with GNOME yet. I am using the Intel HD IGP video card with the open source nouveau graphics driver. I had no problems during the installation process with either Ubuntu 10.10 64 bit or OpenSUSE 11.4 64 bit so long as I stuck to the default nouveau graphics drivers. nVIDIA does not support Optimus technology in Linux and they have no plans to do so either.
