This is non-ideal right now so I’ll try to help. You need two things:
- Install
maliit-keyboard
- Use the Wayland session
In this configuration, the virtual keyboard will appear automatically when you focus a tech field using a touch action.
I’m working on improving this so that the virtual keyboard can be manually opened on X11, or on Wayland without a touchscreen. See applets/manage-inputmethod: make it all about the virtual keyboard (!2780) · Merge requests · Plasma / Plasma Workspace · GitLab.
