Based on the Linux driver for the CL511HN which can be downloaded here: Generic_Ubuntu_CL511HN_Drv_1.0.0031.zip
The CL511HN and GC573 (Live Gamer 4K) are very similar and their drivers are mostly interchangable. Though the firmware differences mean that some modes won't work on the LG4K.
This was tested on Ubuntu 20.04 LTS and Fedora 32. Linux distributions other than Ubuntu (such as Fedora) might require the patches found on the fedora
branch.
Caveats:
./build.sh
fedora
branch if it doesn't compile and try againsudo ./install.sh
sudo modprobe cx511h
or reboot
