Live Gamer 4K Linux driver

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:

  • Driver needs to be recompiled/installed manually every time there's a kernel update
  • RGB LEDs are not supported and will keep flashing red
  • Scaler doesn't seem to work so selected resolution has to match input resolution

How to

  • clone git repository
  • run ./build.sh
    • Note: switch to fedora branch if it doesn't compile and try again
  • run sudo ./install.sh
  • run sudo modprobe cx511h or reboot

ToDo

  • Make driver load automatically
  • Maybe see if we can send a signal to turn off the LEDs by looking at the Windows driver
  • Check some audio issues in OBS and see why RGB24 doesn't work in there either
