I have read through the other posts, and even worked through the Wikis (Graphics/Newcons), but after reading the /usr/ports/UPDATING blurb about STABLE releases I didn't think it would affect my system. I'm currently running an Intel HD 3000 system (no optimus), FreeBSD 10.0-RELEASE-p1, and /var/log/Xorg.0.log shows different errors depending on if I use a /etc/X11/xorg.conf file, or not. Without /etc/X11/xorg.conf I get "Failed to load module 'fbdev'", with I get "failed to open /sys/class/backlight/True/max_brightness for backlight control: No such file or directory.'"
