Tablet mode in KDE? (auto-rotate, virtual keyboard)

This is actually a setting in KDE’s System Settings under

Should someone stumble on this topic while troubleshooting:
If you are on Arch or NixOS and the first option ‘Automatically enable…’ does not work, this is because for this to work pinctrl_tigerlake needs to be loaded before soc_button_array.

To fix this in Arch:

add

MODULES=(pinctrl_tigerlake)

to /etc/mkinitcpio.conf

---

To fix this on NixOS
add

  boot.initrd.kernelModules = [ "pinctrl_tigerlake" ];

to configuration.nix

You can manually unload and reload it: sudo rmmod soc_button_array && sudo modprobe soc_button_array Or add pi…
