Hi ,
I install a fresh new OpenBSD 5.9 on this machine http://sprunge.us/gRJU . When X start, I get this log: http://sprunge.us/ZaUM I fix the "(WW) checkDevMem: failed" problem setting machdep.allowaperture=1 in /etc/sysctl.conf with same problem, no image on external monitor via HDMI output. The xrandr log is http://sprunge.us/VQGV . Hmmm, any idea ? Thanks. See you.
