The 'drm-fbsd12.0-kmod' from pkg [4] behaves the sames as if I build it manually from ports. On 12.1-RELEASE it worked just fine. > > You need to upgrade to 13-CURRENT and use drm-devel-kmod. I don't think this is the root cause. I am seeing the exact same issue after upgrading a Sandy Bridge machine with on-chip-GPU to a recent -STABLE. Worked perfectly fine before with the abandonware-i915kms in base as well as with drm-legacy-kmod. Now both are showing a mere black screen, just like Nils reported. Maybe the recent MFCs of linuxkpi stuff broke something. I'll build some kernels and modules and see if I find the issue. Meanwhile, if it's been discovered (and fixed) already, let me know. Riggs
