First, you say that you are EFI booting. This is contraindicated for amdgpu. (See below.) Then you say that you boot with drm-*-kmod loaded. How are you loading it? It should not be loaded at boot, but from rc.conf. pkg-message file in the port: The experimental drm-next-kmod port can be enabled for amdgpu (for AMD GPUs starting with the HD7000 series / Tahiti) or i915kms (for Intel APUs starting with HD3000 / Sandy Bridge) through kld_list in /etc/rc.conf. radeonkms for older AMD GPUs can be loaded and there are some positive reports if EFI boot is NOT enabled (similar to amdgpu). For amdgpu: kld_list="amdgpu" For Intel: kld_list="/boot/modules/i915kms.ko" For radeonkms: kld_list="/boot/modules/radeonkms.ko" Please ensure that all users requiring graphics are members of the "video" group. -- Kevin Oberman, Part time kid herder and retired Network Engineer E-mail: rkoberman@gmail.com PGP Fingerprint: D03FB98AFA78E3B78C1694B318AB39EF1B055683
