As bugs, you MUST choose "sddm" as your default Display Manager when you install KDE with "force-overwrite". If NOT, you will find sddm runs with the other display manager you chose as "lightdm" at the same time. It cause your lost all graphics and control with your PC after ONE second you see the Login screen. If it happens, don't worry. First you can reboot your PC with System Request: Hold on Alt + SysRq key (or PrintScreen key), then press these keys one by one: R, E, I, S, U, B. When you press B with hold Alt + SysRq, your system will reboot. Then, when you see the Login screen, you must press Ctrl + Alt + F1 immediately. And you enter the console. Login and exec the command: $ sudo dpkg-reconfigure sddm Then choose sddm as your default display manager, and reboot. $ sudo reboot And your desktop will work normally. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1490659 Title: package kde-config-telepathy-accounts (not installed) failed to install/upgrade: trying to overwrite '/usr/share/accounts/services /google-im.service', which is also in package account-plugin-google 0.12+15.10.20150723-0ubuntu1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ktp-accounts-kcm/+bug/1490659/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
