Here's a quick and simple C program that reads a packet from the accelerometer once per second, and rotates the screen to a new orientation if the orientation has changed.

I don't mean this to conflict with Paul's excellent work on Gestures; my reason for writing it is so that it can be used as an always-on daemon in the OM distributions. (Full gesture interpretation is more CPU heavy and requires reading data more often than once per second, so perhaps that will be done on-demand instead of always-on.)

The code is: http://github.com/cjb/freerunner-rotate/tree/master/rotate.c?raw=true

There's an ARM binary here (chmod a+x rotate && ./rotate): http://dev.laptop.org/~cjb/rotate

I found that rotating the desktop area in landscape (using xrandr) makes the XGlamo eat the CPU on my GTA-02 system.

Rotating the display head (xrandr --output default ...) works without major CPU load.

By using no libxrandr, but invoking xrandr commands, it only depends on the accelerometer.
