The odd thing is that it doesn't come through as a Goodix, but this tablet / laptop does have other Goodix hardware (specifically, the fingerprint scanner on the power button). The pen behaves in the same way that you described before, so I'm thinking the same solution should suffice.

I'm currently running on Arch Linux, and have also explored using the xf86-input-wacom driver to no avail. This is employed by a Dell Inspiron 7306 2 in 1 laptop, and the Pen (which comes with it) is technically the Dell PN771M, manufactured by Goodix/Shenzhen.
The Digitizer/Pen ID is 27c6:0111, the prefix of 27c6 suggesting that it is a Goodix. I just wanted to see if I could get your assistance with adding support for an additional device.
