Xorg.conf file for Acer C300 Notebook/Tablet (Dual head support with 1280x1024)

Supports 1280x1024 on a second screen as well as 1024x768 on main LCD. The following two lines are particularly important:
Option "DDC" "0"
Option "VBERestore" "0"
Without them, the setup breaks unless you wait for X to start before plugging in the external monitor.

Get remote filesize (HTTP HEAD)
