Dell Chromebook 3100 2-in-1 problem with the Touchscreen

Greetings. I'm the currently owner of two Dell Chromebooks, which they both have the driver Goodix in ChromeOS, but, for some reason, None of both can currently use the touchscreen. Not even after update ChromeOS. I decided to become on of them on Developer Mode and install Linux with UEFI full stock and install Arch Linux.

The fact here is, that i installed libfprint and libfprint-tod-git, in KDE Plasma, but it still doesn't give me a Goodix/Touchscreen output with "sudo dmesg | grep -lE 'goodix|touch|hid'", "sudo evtest /dev/input/eventX" and "cat /proc/bus/input/devices".

Only Elan Touchpad and everything else. It even have included the tablet switch mode/process, for when i put the screen behind the Keyboard, but the touchscreen is not working even there. 

Plus, i tried with the tablet mode at my Chromebook with ChromeOS and nothing. Even try with Search tab + Shift + T, and nothing.
