This is a follow on to last week's post about Dual Monitor on Ubuntu/Dapper
I've been using the xorg.conf-ati.20060621 configuration at work with two monitors, but when at home the laptop didn't degrade down to working with the one LCD monitor of the laptop. So, here is a new configuration that lets you switch between a single monitor mode (1024x768) or one large one (2048x768) that can be 'slid over to' by using the mouse. The key press is Control-Alt-+ (the + over on the side where the number entry is). On the laptop, it is Control-Alt-blue_Fn-?
Here the is xorg.conf file:
