I use two external monitors, one connected on the DisplayPort as primary and one on the VGA port as secondary. I am not using the built-in display. I use x11 with xfce and the Intel driver. It all works fine, except that the the primary monitor (on the DisplayPort) goes black at random times. Once black, the monitor reports no signal and goes on stand by. It does not resume working if I move the mouse or type on the keyboard. One way I managed to recover it is to turn the display off with xrandr and then back on. I reported a bug on FreeBSD but I wonder if there are other things I can try or other workarounds less intrusive than the xrandr off/on one that I am using. See here for the bug report, log output, and version info: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=210929 Thanks! Rares
