I have an AMD 380X and it has some issues with KDE (wierd, heavy pixalation when trying to lock, logout, restart and/or shutdown among others), so I looked at the drivers installed and a standard install is xf86-video-ati. Wouldn’t it be better to install the newer xf86-video-amdgpu which is for this ‘Tonga’ card. Is it just a matter of installing the amdgpu one and removing the ati one or is more to be done??
