Upgrade to Ubuntu 17.10 broke login

I upgraded to Ubuntu 17.10 but login is all messed up. Login is "command prompt", or whatever it's called. I have to type in my login credentials then startx to load desktop session.

I need a login manager to I can choose fallback environment. Whatever is default doesn't work right. Not full screen.

  • I did:

    sudo dpkg-divert --remove /usr/share/dbus-1/system-services/org.freedesktop.systemd1.service
    
    sudo apt-get update
    
    sudo apt-get upgrade
    

    to finish upgrade without systemd-shim error. And restored gdm3

    sudo service gdm3 restart
    

    Then installing drivers worked so was able to get my full screen resolution.

    Note: using lightdm doesn't work. Couldn't login. There was login loop.


  • It appears as if a package may have been corrupted during the install.

    Try manually running gdm

    First thing to try is to manually invoke gdm:

    sudo service gdm restart
    

    if this fails, look at the errors with:

    sudo service gdm status
    

    and post them, or continue with the other steps.

    Fixing most broken packages

    Most broken packages can be fixed with a simple:

    sudo apt install -f
    

    Reinstalling

    If apt install -f doesn't help, then try reinstalling gdm, the display manager:

    sudo apt install --reinstall gdm
    

    Try lightdm

    As I've personally haven't had much experience with Ubuntu 17.10, I'm not sure if this would work, but it's worth a shot:

    sudo apt install lightdm
    

    This will install lightdm, the display manager used before ubuntu switched to gdm.


  • There was a failure in gnome-packages of version 3.28.0 (3.28.1) which concerned gdm. Then gdm had cipher-salad. Apparently this looked like an attempt of attack where somebody tried to install ransomware.

    In gnome-packages of version 3.28.2 this bug (ransomware?) is fixed.

    You for Ubuntu would have to wait until next update of gnome-packages.
