Hi Thomas, after discussion with Niclas and I explained him that 12.1-RELEASE works but 12-STABLE not, he mentioned to build and install "drm-fbsd12.0-kmod" from ports, but also "gpu-firmware-kmod" from ports (instead of prebuild pkg), what fixed the issue in my case. Now startx and i3 works fine. Here how I installed the two ports; https://github.com/NilsJohannsen/BSD-Journal/blob/master/desktop/drm/install-drm-intel.sh Here my hardware probe: https://bsd-hardware.info/index.php?probe=2e8c0ef401 Regards, Nils Gesendet: Samstag, 08.

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. > Whiskey Lake isn't supported by drm-fbsd12.0-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
