I think what you meant here is the WM decides whether the screen should be rotated or not - all the 'external input' provides to the WM is some hint that e.g. the _device_ has been rotated? WM could decide to NOT rotate the screen, if the current app only works in one orientation. > be this an accelerometer, or like the g1, opening up the > screen, so be it. as long as > 4.1 the current status of this rotation state can be queried at any time (you > can ask what position the device is in or the screen is opened up or not etc. > etc.) > 4.2 you can get an event when this state changes really quickly (not have to > wait a while). > Indeed. I've not played with the fso orientation API, but it looks like that is exactly what it's designed to provide. It seems sensible for this to be over dbus - given that it's an abstraction of hardware. > if it were me... i'd even have the current desired rotation state be a > property > on the root window too... but at this point its moot - dbus or property. If the root window will only work in one orientation, specifying that orientation through a window property would be consistent - but ideally wouldn't we want the root window to be able to cope with being rotated to work in either orientation? Or have i missed something special about the root window?
