 === Now automate it on login ===
 To configure xrandr automatically during the first login, save this script to your computer as /etc/X11/Xsession.d/45custom_xrandr-settings:
-<bash>
+<pre>
 # If an external monitor is connected, place it with xrandr
 # External output may be "VGA" or "VGA-0" or "DVI-0" or "TMDS-1"
 EXTERNAL_OUTPUT="VGA"

 When X starts, it will be mirrored across both screens until someone logs in. At that point this script will execute and xrandr will position the external monitor.

 === Note for Gnome users ===
 Gnome places the menu bar on screen 0 and thus with the Intel chip and driver Screen 0 (the external VGA monitor) will always be the default display if it is connected. This applies even if the external monitor is switched off but the cable connected: if you have a blank laptop monitor check if you have anything plugged in to the VGA port. Also beware that desktop icons and windows can disappear into the invisible parts of the virtual display. (see diagram below).  If you want the panel(s) to appear by default on a different head, drag it to the head you want it on and GNOME will keep it there.

 A Virtual line is needed in the 'Display' SubSection of the of xorg.conf; it determines the size of the frame buffer into which the displays must fit. Without it the maximum virtual size will be limited to the size of the largest display that was connected when X was started. The maximum virtual size cannot be changed once X starts so needs to be large enough to accommodate the largest combination of displays you want to hotplug without having to restart X. If it is greater than 2048x2048 and you are using an Intel 945 (or less) chip then DRI is not possible. Making the Virtual size square makes rotation easy. A bigger Virtual requires more memory.
