My wife’s PC is an HP Envy 360 2in1 with only openSUSE 15.1. It has always been used as a laptop, never in the tablet mode.
Today she had to reboot for the first time in months. When login screen was expected she instead got a large touchscreen style, virtual keyboard. Touching any but one of the keys produced no response. The exception was a little symbol in the lower right corner that resembles a keyboard. When that ‘key’ is touched the screen switches to a graphical login screen, the same one she’s used to, however as soon as she touches any key on the physical keyboard the screen immediately reverts to the virtual KB with the same behavior described above. This is thoroughly repeatable, and I am at a complete loss to help her get logged in.
