If I pa= rse the ports tree correctly there is no X support, or possibly only suppor= t as a generic VGA device. Is that correct? Is anybody on freebsd-arm wor= king on graphics? If there's active interest I may be able to help, but it= 's not a project I want to take on alone. I see three packages in ports/graphics: drm-legacy-kmod is marked broken for aarch64 drm-current-kmod is only for x86 and PPC drm-devel-kmod is only for x86 and PPC Historically getting graphics cards to work has often required binary-only = Linux drivers which wouldn't be available for ARM. Maybe that's not true f= or Radeon these days. But even today the strategy seems to be "take whatev= er Linux can give us".
