My laptop spec : - Asus X555BP - BX921T, - AMD A9-9420, - Radeon R5 Graphics + R5 M420 (dual graphics), - RAM = 4GB, - storage = 1TB HDD, - Distro = VoidLinux, - DE = XFCE 4.14, - Kernel = 5.8.18_1 I have tried updating the bios, but it turns out that my bios is up to date -> There is a pop up "build date is too old" when updating the BIOS. I've also installed mesa-vulkan-radeon as my GPU driver but still doesn't solve this problem. According to https://docs.voidlinux.org/config/firmware.html , AMD Microcode is bundled with linux-firmware-amd which is already bundled with xorg as well.
