I have the same problem with and Aspire One D250 and I totally agree that xrandr should avoid going further than the capacity of the driver.
This is the way I managed to avoid hangups without enabling and disabling compiz
I've created three custom keyboard shortcuts to diferent xrandr configurations
1. super+F1 calls --> xrandr --output LVDS1 --mode 1024x600 --output VGA1 --off 2. super+F2 calls --> xrandr --output LVDS1 --off --output VGA1 --mode 1440x900 3. super+F3 calls --> xrandr --output LVDS1 --mode 1024x600 --output VGA1 --mode 800x600 --right-of LVDS1
1. Is my internal LCD only config 2. Is my external LCD only config 3. Is a dual head config for projector use that can be further modified by using the display-configuration applet
