Ok, so finally I have raspad-launcher installed and working, and auto-rotate installed and working.
So, I followed the instructions for the virtual keyboard as found here:
https://docs.raspad.com/en/latest/quick_user_guide.html#install-virtual-keyboard-on-raspad
Now, the last step says after every boot I have to click "General Access -> Onboard" to enable the virtual keyboard. Mind you the picture below shows "Universal Access" and not "General Access", but neither are present in the menu you get with raspad-launcher.
There is nothing between accessories and help.
So, I get no virtual keyboard.
Now the downloaded image version had an icon near the top right that would show a keyboard. Is that one different than this one? In any case, no on screen keyboard for me. And no, I cannot use the downloaded image, it does not support en/US or the US keyboard.
So, how do I get an onscreen keyboard?
