Hello!
Sometimes ago I made a patch that allows to configure Devices, Screens
and Layouts belonging to the different seats in a multi-seat
environment. It is useful for the setting up with several videocards
using propritery drivers (I've tested with Nvidia).
Because my patch has not been sesolved upstream, I resend it again
adopted to the current master.
Oleg.

Subject: [PATCH] config by seat
Added capability of specifying "MatchSeat" option in the ServerLayout, the Device and the Screen sections for selecting default sections for the seatmultiseat: capability of splitting xconfig objects across seats
