Can you track down the exact cause? Try downgrading mesa-dri to 18.2.8 first then to 18.1.9. > I'm on 12-STABLE / AMD Radeon 7450 with radeonkms.ko. > The server works fine as soon as I connect the monitor. radeonkms from drm-fbsd12.0-kmod with xf86-video-ati? Can you try drm-fbsd11.2-kmod first then xf86-video-ati-legacy? Can you try "DRI" "2" or "AccelMethod" "EXA" in xorg.conf per radeon(4x) manpage? Can you show pciconf output to avoid ambiguity? $ pciconf -lvcb | sed -n '/vgapci/,/@pci/p' > Is this a known issue? Not enough details.
