Is there a gui application for managing multiple mice/keyboards?
9.04 only
Roland, regarding your query Its was very much possible using a tool called
gnome-device-setup
I used it myself on 9.04
You can see it in action http://www.youtube.com/watch?v=nS06QjHlrwk&feature=related
Sadly, the links are broken http://people.freedesktop.org/~whot/gnome-device-setup
This has been taken from http://who-t.blogspot.com/2008/07/gnome-device-setup.html
the gnome-device-setup seems to me like a frontend to xinput. With these commands you are able to create more virtual pointers:
xinput list
xinput create-master <name>
xinput reattach <input-id> <pointer-id> (id you can get from xinput list)
have fun.
