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:

There's an ARM binary here (chmod a+x rotate && ./rotate):

There's also a complete rewrite at


And you're welcome to make patches against the GIT repo here:



Would anyone else be interested in being the maintainer of this package? It would involve packaging it up in bitbake/OE and trying to persuade the various OM distros to include it by default. (Perhaps with an on/off control panel entry in distros that make that easy to do?)
