Can't login to Linux via TeamViewer App

MaxMustermann

I can't login to Kubuntu 16.04 and TeamViewer 9 (we've only bought licenses for 9 so we can't use anything newer) from the TeamViewer Android app. Connecting via TeamViewer isn't a problem but logging into Kubuntu doesn't work. My password doesn't work when it's through a TeamViewer connection. Local login is no problem. The password does contain special characters but nothing exotic.

If I log in and type the password into a text editor most of the letters are the same but some are mixed up. It's probably important to note that the destination computer has a German (Germany) keyboard connected. After adding the an English (US) keyboard layout to the possiblities on the destination computer typing the password into a text editor shows up correctly with EITHER keyboard layout selected.

Despite that success I still can't login when the screen is locked. How do I get it to work?
