Xorg configuration

Xorg is mostly self-configuring now, but you can still configure it with files.

Locations

/etc/X11/xorg.conf	X configuration
/etc/X11/xorg.conf.d/*.conf	Add/override configuration

Auto-Configure

sudo Xorg -configure :1  # autoconfigure xorg in /root/xorg.conf.new (change to :2 if already running xorg)
