I would like to set my AMD Radeon R7 M260 to the primary VGA. I can see the card in the device manager, and there is a little yellow triangle . When I click on the Radeon settings ( to change priority) it gives me an error: No AMD graphics driver is installed, or the AMD driver is not functioning properly. Please install the AMD driver appriopriate for your AMD hardware.
Sometimes it gives another message about the OpenGL...
Can somebody help me?
