I have connected my sole digital monitor to the DVI output. This setup worked without any problems on FreeBSD 10.3. It also continues to work without problems on Debian 9. On FreeBSD 11.2, the intel graphics driver fails to detect the DVI output of the graphics card, and consequently, I get a blank screen after the driver = is loaded, either manually through the kldload command or by starting Xorg. This behavior also occurs if I try to use the graphics/drm-stable-kmod port, leading me to believe that it is a fundamental kernel/driver regression. I have attached the relevant FreeBSD kernel messages and Xorg logs, and also the Debian Xorg log for reference. --=20 You are receiving this mail because: You are the assignee for the bug.=
