I just upgraded to 16.04 and yes, I was aware of the driver changes they made. This is a test to see if I should upgrade my main PC which also has a AMD GPU. My question is, how can I tell which I was put on? I checked Additional Drivers and it says "do not use the device" below "Using Processor microcode firmaware for AMD CPUs from amd64-microcode (proprietary):".
Here is the lspci -nn | grep VGA output:
00:01.0 VGA compatible controller : Advanced Micro Devices, Inc. [AMD/ATI] BeaverCreek [Radeon HD 6520G] [1002:9647]
I am using a laptop, if it matters.
And for my Desktop, I get this:
01:00.0 VGA compatible controller : Advanced Micro Devices, Inc. [AMD/ATI] Tahiti PRO [Radeon HD 7950/8950 OEM / R9 280] [1002:679a]
Checking additional drivers gives me an empty field.
Still no solution.
