Magick Rotation does not support slates

[Sean DS]

I have an ACER W501 which is running Ubunto 12.04, it has a device called /dev/input/js0 which is the accelerometer device. I'd like my tablet to do autorotation based on feedback from the accelerometer. I understand magick rotation doesn't currently support this but I also feel it's a critical feature for a slate and this project is the most relevant one that could implement it.

At the moment I have buttons for rotation on the desktop, it would be nice if an acpi event triggered by the accelerometer could call those scripts and do the rotation, unfortunately I don't know where to start in doing it myself, although I'll spend a few hours today looking into it.

Thanks,

Sean.

Hi Sean,

We've discussed adding accelerometer support. However we did and do not have access to a x86 slate.

I'd be interested in any code you come up with or information that would help with developing code. Accelerometer name, location of any file(s) providing rotation state signal, nature of signal(s), etc.

There are 2 or 3 Python applets for accelerometers around. I don't think any of them have seen any development in quite a while. I have the bookmarks somewhere if you are interested in code examples. Provided I can find them.

Hello Favux,

Yes, I think those bookmarks will come in useful, could you send me
them? The device is listed as a joystick, so I've been trying to use
joystick calibration tools but not so surprisingly the values it's
returning are junk, so I think if some people already have a way of
returning meaningful data from the accelerometer I may be able to come
up with something, or at least work out if the old scripts are useful at
all.

Thanks for getting back to me,

Sean.
