  1. When I install this I get a blank screen without a taskbar or a wallpaper or desktop. Just a window asking WiFi passwords.

  2. I would recommend add an “sudo apt dist-upgrade” after “sudo apt-get install kubuntu-plasma5-desktop plasma-workspace-wallpapers” because without some packages wouldn’t be upgraded and you will end with a white screen in sddm and no session after you change the sddm theme.

    The steps would be:
    sudo apt-add-repository ppa:kubuntu-ppa/next
    sudo apt-get update
    sudo apt-get dist-upgrade
    sudo apt-get install kubuntu-plasma5-desktop plasma-workspace-wallpapers
    sudo apt-get dist-upgrade

    Then reboot ;)

  3. I got the white screen and can’t get back to terminal. I’m a newbie… any ideas how to get back to the terminal? I get the login screen but of course once I login I get the white screen and can’t do anything.

  4. Are these steps valid? Keep getting the following:
    sudo apt-get install kubuntu-plasma5-desktop plasma-workspace-wallpapers

    E: Unable to locate package kubuntu-plasma5-desktop
    E: Unable to locate package plasma-workspace-wallpapers

  5. I got everything to load right, but now I get a blank (black) screen where I can still see the mouse cursor. I can use grub to use fsck and it seems fine (other than a dirty bit from rebooting because the filesystem was not unmounted correctly). I can log into root shell, but I don’t no where to begin troubleshooting. I remember an error before rebooting where it went black with an error in the top left corner, something “k*server” crashed. I don’t remember what was in *.
    Has this happened to anyone else?
