           Product: Wine
           Version: 1.7.18
          Hardware: x86-64
                OS: Linux

I have a working systemd multiseat setup.

seat0 has a keyboard and a mouse attached. Seat1 has also two usb joysticks.
But when I run `wine control` on seat0  the game controller menu shows the
joysticks from seat1 and the buttons and axis are working.

First I thought that it might be a win registry option, but a clean WINEPREFIX
made on seat0 does also shows the joysticks from seat1.

Wine accesses joysticks using /dev/input/js* and /dev/input/event*. In what way
you want this to be different?

When a device is attached to a seat (an udev rule is made with
ENV{ID_SEAT}="seatn") Wine should only use the devices on the same seat Wine is
running from.

I also asked this question to the systemd developers and they explained me that
the joydev module is old and unmaintained. Joysticks/ applications should only
use evdev. [1]

That is the only part Wine should change: drop access via /dev/input/js*

For other users with the same problem, this behavior can be solved with the
following steps:
- Blacklisted the joydev module. The /dev/input/js* devices are gone.

- Remove the world and group read/write flags with:
# setfacl -m other::--- /dev/input/event(joystick)
# setfacl -m group::--- /dev/input/event(joystick)
The joysticks are only accessible by the user
