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 > [email protected] > http://lists.meego.com/listinfo/meego-dev > _______________________________________________ MeeGo-dev mailing list [email protected] http://lists.meego.com/listinfo/meego-dev
