I have A8-7600 Radeon R7 Kaveri.
I want to buy a discrete videocard (probably R7 240) and I wonder, will the Dual Graphics technology work on Ubuntu 18.04.3 LTS ?
If so, which driver should I use? As I understand, currently I have two open-source modules (radeon, amdgpu) and "radeon" is in use. Maybe there is another driver?
