Thank you for the hint. I inspected that, but the PCI-IDs actually look the same: 00:01.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Trinity [Radeon HD 7480D] [1002:9993] (A4-5300) and 00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Richland [Radeon HD 8670D] (prog-if 00 [VGA controller]) (A10-6700) Looks like the VGA BIOS is really different: # diff vgabios_a4-5300.bin vgabios_a10_6700.bin Binary files vgabios_a4-5300.bin and vgabios_a10_6700.bin differ Guess I will have to to "update" the VGA BIOS then.
