    Default The login screen cannot display

    Last week, after install successful OpenSUSE 11.1 from the KDE4 LiveCD, I install the kde4-amarok-2.0 with yast2. The installation was fail and after that I cant login to desktop through the login screen. After the green boot screen finished loading, this message error box appeared:
    "No greeter widget plugin loaded."
    After I click the "OK" button of the message box, the screen returned to the console login screen.
    I must login with this then use startx to start the X.

    I also cant shutdown, restart or lock my laptop. I can only logout to the console screen and then shutdown my laptop here.

    Thanks for read and... Any ideas?

    More infos:

    Boot failsafe and at the login prompt, login with your username and password, then
    do this:

    mv /home/*usernme/.kde4 .kde4old

    (*username = replace with your username, and notice the period . )

    when done reboot
    ===============

    see if that helps, it will create a totally new .kde4 folder

    Thanks for reply. But there is no change. I still have to use startx to start KDE.

    My English is not good, so perharps u haven't understood me. This is my problem:
    - The login screen doesn't appear, and there is a dialog with the content: "No greeter widget plugin loaded. Check the configuration" and an OK button.
    - When I click the OK button, I am brought back to the console login screen (lv3 login).
    - I can connect to the X server and start KDE with the command startx.
    - I cannot lock, shutdown or restart my laptop. When I click Lock button to lock my session, a dialog appears. And this is its content:
    Will not lock the session, as unlocking would be impossible:
    No appropriate greeter plugin confifured.
    Anyway, this is my menu.lst:
    # cat /boot/grub/menu.lst

    Hi thangola

    This is a strange one. I found a similar thread here.

    As you can see they were missing kde4-kdm package. Check with

    rpm -qa |grep kde4-kdm

    For reference, I get

    rpm -qa |grep kde4-kdm
    kde4-kdm-branding-openSUSE-11.0-81.48
    kde4-kdm-branding-upstream-4.1.3-152.6
    kde4-kdm-4.1.3-152.6
    Hopefully its something as simple as this.

    Thanks for reply, deano_ferrari ^^.
    It seems this is my problem. When I check my packages:
    Code:
    rpm -qa |grep kde4-kdm
    kde4-kdm-branding-openSUSE-11.1-66.4
    kde4-kdm-4.1.3-10.1
    I don't have a package kde4-kdm-branding-upstream installed. When I choose to install this package with yast, there is a conflict:
    Code:
    kde4-kdm-branding-openSUSE-11.1-66.4.i586 conflicts with namespace:otherproviders(kde4-kdm-branding) provided by kde4-kdm-branding-upstream-4.1.85-8.1.i586
    What should I do now?

    Login to a CLI as user
    go su

    then do

    zypper in kde4-kdm-branding

    (I think)

    Zypper/Usage/11.1 - openSUSE

    you might just try
    zypper up

    The result (^o^)/
    Code:
    "kde4-kdm-branding-openSUSE" providing "kde4-kdm-branding" is already installed... Nothing to do
