Have you tried with the xf86-intel in ports. That actually works 
better for most. Also try SNA. What does pciconf -lvbc show for graphics?----

  and installing the experimental xf86-video-intel driver it is partially  
working. What's not working is: - 3D-acceleration - multi-monitor support (only 
tried with hdmi), after loading the  i915kms driver the output is duplicated, 
but there is no way of  controlling the outputs independently (xfce also shows 
only one  connected display) - Xorg refuses to start unless I kldload i915kms 
manually before trying  to start Xorg - there are some rendering issues (pink 
lines, weird transparency where  there should be no transparency), but 
 I don't know if these are related  to i915, the experimental xf86-video-intel 
driver or the software  renderer  On 2016-05-23 10:12, Matthew Macy wrote: >
