Making it Work

Somehow w_scan works with Ubuntu 18.04.1 LTS but I have not been able to get picture. The driver may need a patch to improve signal quality or something. It did manage to get some signal because I got Kaffeine to show program guide information, but the picture remained a black screen and no audio.

Firmware

The required firmware I believe is included with Ubuntu 18.04.1 LTS. (See dmesg)

Drivers

cx231xx driver is used.
