[ale] video woes

[Brian Pitts]

Out of curiosity, what does

xrandr --verbose

output when your external monitor is connected?

In my setup, my laptop display supports 1280x800 and my monitor supports
1440x900

I am able to enable dual-display with

xrandr --output VGA --auto --right-of LVDS

and disable it with

xrandr --output VGA --off

I am able to switch from my laptop display to my monitor with

xrandr --output VGA --auto
xrandr --output LVDS --off

and to switch back with

xrandr --output LVDS --auto
xrandr --output VGA --off

My xorg.conf is below for reference. I calculated the "Virtual" line by
adding the horizontal resolution of my two displays and taking the
maximum vertical resolution.
