I have a Haswell i3 which runs X fine with vesa, but when I > quit X, the machine crashes hard and requires holding the power button. The problem with sc and the new X system is that on return from X to console mode the sc driver can't regain control of the screen to display anything. It doesn't crash, but you get a black screen so you might think it's not responding. In fact, if you (carefully) type "shutdown -r now" (or any other command) it will respond. If that's what's happening, switching to the vt driver will help. If you're genuinely getting a crash though it's not an sc versus vt problem. To use the vt driver on my system I have the following two lines in /boot/loader.conf kern.vty=vt i915kms_load="YES" Try that (and reboot of course) and see what happens. -- Those who do not learn from computing history are doomed to GOTO 1
