Tablet mode, screen rotation, onboard screen keyboard not working correctly Lenovo Thinkpad Yoga L390

Hi,

I just installed Mate 18.04.3 on a Lenovo Thinkpad Yoga L390 laptop and i'm having a couple of issues with the (touch) screen and on screen screen keyboard.

  1. Automatic screen rotation doesn't seem to work. Also i haven't found a way to check if it is actually activated.

  2. Onboard, the on screen keyboard doesn't show up automatically when trying to enter into a text field or editing text even though this is activated in the onboard control settings

  3. The touchpad isn't locked when screen is rotated in tablet mode. (Keys are locked)

FYI: In the "normal" ubuntu version 18.04.3 i installed previously everything used to work just fine out of the box after install.

Did all the updates and checked for additional drivers but still no change. Any advice / solution would be much appreciated.

Thnx!
