One CTL-472 not working in Gentoo after installing wacom packages

Thanks Thomas. The sysinfo script didn't detect a pen sensor either; it shows a touchscreen from ELAN rather than Wacom but no pen. Are you sure your device supports the PN556W stylus? Searching for info on the XPS 15 9550 it sounds like it only has a traditional capacitive touchscreen. If that's the case, you'll only be able to make use of purely-capacitive pens. An "active pen" like the PN556W requires special support from the touchscreen controller to work.
Hi Thomas. Could you please first make sure that you are running an X11 session? You can check your current session type by running echo $XDG_SESSION_TYPE inside a terminal. If it prints out "wayland", then you'll need to switch the session type. If you use the GNOME desktop, you should be able to do this by logging out, clicking the "gear" icon next to the login button, slecting "GNOME on Xorg", and then logging back in. Afterwards, run the echo command again to double-check that you've indeed started...
