I have AMD iGPU(integrated)and dedicated(dGPU) cards:
00:01.0 VGA compatible controller : Advanced Micro Devices, Inc. [AMD/ATI] Richland [Radeon HD 8610G] [1002:990f] 01:00.0 Display controller : Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT [Radeon R7 M260/M265] [1002:6900] (rev ff)
Now my dedicated GPU is supported by the driver but integrated is not.I own a laptop and due to BIOS limitation i can not change boot to dedicated GPU only.Is there any way that i can use Live CD to edit configuration manually in grub so i could set it to pull the dedicated graphics only as soon as it starts.
With OpenSource drivers for some reason only my iGPU works and dGPU never works neither there is a way for me to activate it.
Any advise will be appreciated .
