            Bug ID: 101993
           Summary: Support enumeration of Framebuffer devices and input
                    devices with udev in the Framebuffer backend
           Product: Wayland
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: medium
         Component: weston
          Assignee: wayland-bugs at lists.freedesktop.org
          Reporter: bluescreen_avenger at verizon.net

While Kernel mode setting is the norm for most devices that end up being the
users card0, If you are going to try to go for a multiseat configuration, odds
are the best way to do it as of now, is probably USB DisplayLink devices, of
which although do support Kernel Mode Setting, Its harder to get them working
with Kernel Mode Setting.

If it could be added, then Framebuffer devices could be added to seats, and
weston could be started with --seat=seat1

Of course, you'd also need to add
SUBSYSTEM=="graphics", KERNEL=="fb*", TAG+="uaccess"
