Getting some tips here :< Another radeon/amdgpu problem with an early-GCN based APU
Trying to force amdgpu :< [Solved] KDE with Wayland crashes after login / Applications & Desktop Environments / Arch Linux Forums
This is Northern Islands GPU not Southern Islands GPU though so no amdgpu support supposedly only radeon. Trying to force amdgpu now though.
Added radeon.si_support=0 amdgpu.si_support=1 to grub config then update-bootloader
powercycle and see what happens.
-Thanks
