Oh, I removed the logic on purpose, becau
Unfortunately on ARM-32 systems dev_t can be 64bit and thus we cannot
store it easily in void* keys for hashtables. Fix that by passing a
pointer to the dev_t variable instead.

A session-device is a device that is bound to a seat and used by a
session-controller to run the session. This currently includes DRM, fbdev
and evdev devices. A session-device can be created via RequestDevice() on
the dbus API of the session. You can drop it via ReleaseDevice() again.

This enables the multi-session capability for seats that don't have VTs.

seats now also get the multi-session capability.

Session compositors need access to fbdev, DRM and evdev devices if they
control a session. To make logind pass them to sessions, we need to
listen for them actively.
However, we avoid creating new seats for non master-of-seat devices. Only

A seat provides text-logins if it has VTs. This is always limited to seat0
so the seat_is_seat0() check is correct. However, if VTs are disabled, no

VT numbers start with 1. If a session has vtnr == 0, we must not assume it
is running on a VT.
Note that this could trigger the assert() below as CreateSession() sets
vtnr to 0, not <0.

The seat->vtconsole member always points to the default seat seat0. Even
if VTs are disabled, it's used as default seat. Therefore, rename it to

Currently, Activate() calls chvt(), which does an ioctl(VT_ACTIVATE) and

Furthermore, compositors often need to clean up their
