I'm currently running Ubuntu 15.10 and decided I'd try the AMD prop driver for X on my laptop. The device is listed as a Radeon HD 7400G (00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Trinity [Radeon HD 7400G])
According to what I can find on the site the device and X version are all supported with this version. I tried to build it for the machine but the build fails and I don't see really why the build fails. Checking the log it says 'something' is missing but no real details. I've installed all prereq's I can think of but still had no luck.
Either way I decided to just try installing the pre-built once and when it runs the check, I see: ./amd_dcm64: No supported adapters detected
My adapter appears to be listed in the supported devices, does anyone know how this does the validation for the hardware?
