You'll need the above if you using WiFi, but for your graphics can you please take a look/share the output of: lspci | grep -i VGA and lshw -C cpu lshw -C display The above will show which APU you are using and its GPU cores. Then it is a matter of looking here for the corresponding GPU chipset and microarchitecture you need to enable in the kernel: https://wiki.gentoo.org/wiki/AMDGPU#Feature_support before you check what firmware blobs you also need to include, from this table: https://wiki.gentoo.org/wiki/AMDGPU#Firmware_blobs_for_a_known_card_model Alternatively, as Wol mentioned, you can set up your kernel graphics drivers as modules (temporarily) and inspect dmesg to find out what firmware is being loaded. Then use this information to add the firmware file names to be built in the kernel and also configure to be built-in any kernel graphics drivers.
