Ubuntu: lightdm-gtk-greeter-ubuntu “crashes” after installing KDE4.10


I have a weird problem, which I didn't found anything on the internet about.

I installed KDE4.10 (from kubuntu-ppa/backports) a week ago, and it changed the loginscreen. After there was something weird with my sound (doesn't matter anymore) I uninstalled kubuntu-desktop, rebooted and then i just got mountall: connection to plymouth disconnected. After installing kubuntu-desktop again. The problem was gone, but I had again this KDE-like loginscreen.

Later I figured out, that i can change the greeter in


from greeter-session=lightdm-kde-greeter to greeter-session=lightdm-gtk-greeter-ubuntu but this brings back the old problem which can be seen in the picture i linked above.

Does anyone know how i can fix this? I would like to have the standard-loginscreen again.


the greeter session that worked in my case is:

If you want using boot screen ubuntu just remve package plymouth-theme-kubuntu-logo and plymouth-theme-kubuntu-text then reinstall plymouth-theme-ubuntu-logo plymouth-theme-ubuntu-text.
