[systemd-devel] joystick doesn't respect seat rule
Hey,
I have created an udev rule for an usb hub with loginctl attach so every
device I plug-in will go to seat1
$cat /etc/udev/rules.d/72-seat-usb-pci-_00_1a_0-usb-0_1_4.rules
TAG==seat, ENV{ID_FOR_SEAT}==usb-pci-_00_1a_0-usb-0_1_4,
ENV{ID_SEAT}=seat1
Nevertheless, when I plug-in a joystick on seat1, it is also working on
seat0
I would expect the same behavior as a keyboard or a mouse. A device on
seat1 does not interact with seat0
$ jstest /dev/input/js0 #run on seat0
Driver version is 2.1.0.
Joystick (DragonRise Inc. Generic USB Joystick ) has 7 axes (X, Y,
Z, Rx, Rz, Hat0X, Hat0Y)
and 12 buttons (Trigger, ThumbBtn, ThumbBtn2, TopBtn, TopBtn2, PinkieBtn,
BaseBtn, BaseBtn2, BaseBtn3, BaseBtn4, BaseBtn5, BaseBtn6).

Are you logged in as the same user on both seats?
I think the difference is that with `jstest`, the device doesn't
interact with your seat, but *you* are interacting directly with its
device node, so the only thing that's checked is devnode
permissions...

Re: [systemd-devel] joystick doesn't respect seat rule
So the seat assignment works fine – gdm is added to the ACL.

Kay, please correct me if necessary. Correct. joydev devices are always world-readable as games (SDL, steam, ...) rely on the device-nodes. There are some things to note about joydevs: 1) They are deprecated! No features are added, any new application is advised to use evdev exclusively (event devices). Same is true for mousedev and others. Rule of thumb is: evdev is the only node you should use. 2) Input handling other than mouse (which includes trackpads and touchscreens) and keyboard has never been figured out properly. There is XInput, XInput2 and more, but games still use joydev directly. They ignore seat assignments, they ignore permissions, they ignore evdev. It's a mess and there is currently no solution. No, there isn't even anyone working on it. It's a complex task. So unless someone wants to tackle it, we have to deal with the consequences. This includes: applications will ignore seat-assignments for joysticks, gamepads and more.
