I am no expert whatsoever but on a normal system it is possible to start two X server with their own xorg.conf and thus possibly use different input devices. If you want to only run a single x-server using xinerama I goggled a little and to me it looks like it should be enough to add a coordinate translation of the input device to match the hardware (xinerama) setup. possibly http://www.freedesktop.org/wiki/Software/xinput_calibrator can do this. Those are two "hacks" of course but for example http://linuxwacom.sourceforge.net/index.php/howto/inputdev has a topX, topY bottomX bottomY. so perhaps this is just enough. > > Any Xorg folks on this list want to comment? > > Auke > ___ > MeeGo-dev mailing list > MeeGo-dev@meego.com > http://lists.meego.com/listinfo/meego-dev > ___ MeeGo-dev mailing list MeeGo-dev@meego.com http://lists.meego.com/listinfo/meego-dev

Jeremiah, that use case would likely cause more problems not so much with dual input technically, but with dual output logistically if both screens are active then the kids will fight over what to watch (a fun game to play, but invariably ends with Parenting_Exception being raised) Gary On Sat, Aug 21, 2010 at 12:52 AM, Jeremiah Foster < jeremiah.fos...@pelagicore.com> wrote: > > On Aug 19, 2010, at 13:25, Auke Kok wrote: > > On 08/19/2010 09:54 AM, Abraham Arce wrote: > >> > >> http://www.spinics.net/lists/linux-input/msg10503.html > > > > I'm not aware of any specific requirement for this, and it's really not > that simple per se, and several packages are involved: > > I'm not aware of a specific requirement at the moment, but I can imagine an > IVI situation where you'd want to run MeeGo on two screens in the two > headrests of a car. > > Jeremiah > > ___ > MeeGo-dev mailing list > MeeGo-dev@meego.com > http://lists.meego.com/listinfo/meego-dev > ___ MeeGo-dev mailing list MeeGo-dev@meego.com http://lists.meego.com/listinfo/meego-dev
