Using the ATI Catalyst Control Center (fglrx), I setup two desktops (the multidesktop option) via dual-head. Now I have two mice and keyboards (USB) attached which, using xinput
can be put in two separate groups. Can I lock each group to one screen? And how can this be done permanently? Alternatively, instructions for turning this "lite multiseat" configuration into multiseat are appreciated as well.
This is the xorg.conf as setup by the Catalyst Center:
