Hi Alexander,

Yea, that 0=inactive line in gdm.conf will cause gdm not to load the
default X server -- which on most recent xorg & distro configs, is set
to auto-detect PCI graphics and all input devices (via hal), and
auto-launch a single X instance on them, owning all devices.

So it sounds like the behavior you're seeing would be expected right
now, with that line removed.

Now, in the future, to get back to something multiseat friendly, what
we'd like to have happen is that each X instance (including the
default on) would use something like libudev to find the graphics and
input devices on the system, and heed an attribute on each device
(SEAT_ID) to only grab/use devices that it is intended to own, instead
of grabbing all of them.
