systemd version the issue has been seen with

254rc3-1

Used distribution

Arch Linux

Linux kernel version used

6.4.5-arch1-1

CPU architectures issue was seen on

x86_64

Component

systemd-udevd

Expected behaviour you didn't see

USB devices plugged into the monitor's USB hub work in a plasma wayland session.

Unexpected behaviour you saw

After updating systemd to 254rc2-2, USB devices attached to my monitor's USB hub do not work in Plasma wayland session unless I unplug and replug them (or the USB/Thunderbolt3 cable connecting the monitor to the PC).
The USB devices work fine in a Plasma Xorg session and also in LightDM+web-greeter which uses Xorg.

From what I can tell, rc1 is bad too.

See also Arch bug FS#79144.

Steps to reproduce the problem

Start a plasmawayland session.

Additional program output to the terminal or log subsystem illustrating the issue

Maybe duplicate of #24026 ??
Instead of replugging USB devices, what happens when wayland or anything graphical things started slightly later?
E.g. boot with CLI mode (boot with 3 kernel command line option), then switch to GUI mode (login CLI console and call systemd isolate graphical.target) ?
Or, insert a delay before starting graphical things, e.g. adding the following dropin that starts wayland or plasma (I am not familiar which service should have the following though):

# /etc/systemd/system/foo.service.d/override.conf <-- please replace 'foo'
[Service]
ExecStartPre=sleep 10

I'm using LightDM with web-greeter which do not use wayland. The unit is lightdm.service. But the USB devices (keyboard and mouse, in my case) work fine in the display manager. Only when I start the plasma wayland session from the display manager, do things go wrong.

Nothing changed after adding the drop-in for lightdm.service and booting with systemd.unit=multi-user.target + running systemd isolate graphical.target from the tty.

Thanks. Then, that's not a duplicate of #24026. Hmm...

Is the issue only happens when keyboard or mouse are connected to the USB hub? What happens if they are connected to the machine's USB port?

Though I am not familiar with plasma or wayland, but I cannot find anything spurious in the provided logs.
Could you make them more verbose?

Also, is the key of the issue is in wayland or not? What happens when you use Gnome or any others?

The same issue occurs when the mouse & keyboard are connected to the motherboard's USB ports. Oops, I could have sworn I tested it before, I guess I forgot. And it looks like it only happens with input devices(?), as a USB flash drive is accessible just fine.

Starting a plasma session from the tty with startplasma-wayland doesn't exhibit this issue. 🤔

Booting with systemd.log_level=debug gave me strange results. The issue only appeared the third time I logged in from LightDM. 1.log

Trying it over and over again, with the mouse connected to the front USB port, sometimes it works while the keyboard connected via the monitor doesn't. I tried using SDDM and I couldn't trigger the issue. This is annoying. ☹️

So... something in systemd v254rc1+ broke something USB input related for plasma-wayland sessions started via LightDM?!

Switching from LightDM to SDDM is not an option for me because I need multi-seat support.

One spurious(?) thing I found is that the following symlinks are requested by two devices, and the owner is swapped on replugging.

As you can see, initially the link owned by event5, but later event6.

And, it seems event6 is something important, at least it is managed by logind.

But I do not know if the swapping of by-id or by-path symlinks is essential.
As the mouse devices have unique symlinks, and there is another keyboard related device.

Also, such conflicts of symlinks can be also observerd in v253...

@nl6720 BTW, is it possible to reproduce the issue with LightDM+plasma+wayland without multi-seat setup?

Previously I just commented out the seat specific autologin in /etc/lightdm/lightdm.conf. If I remove all the /etc/udev/rules.d/72-seat-* files, it appears that the issue is gone.
For reference, the files:

$ head -n -0 /etc/udev/rules.d/72-seat-*
==> /etc/udev/rules.d/72-seat-drm-pci-0000_6d_00_0.rules <==
TAG=="seat", ENV{ID_FOR_SEAT}=="drm-pci-0000_6d_00_0", ENV{ID_SEAT}="seat-tv"

TAG=="seat", ENV{ID_FOR_SEAT}=="graphics-pci-0000_6d_00_0", ENV{ID_SEAT}="seat-tv"

TAG=="seat", ENV{ID_FOR_SEAT}=="sound-pci-0000_6d_00_1", ENV{ID_SEAT}="seat-tv"

Hmm, there was supposed to be a rule for the USB CEC adapter, where did that one go...

Could you show all seats and sessions on the machine: loginctl seat-status seatXYZ and loginctl session-status sessionXYZ on single-seat case, and multi-seat case.

The fun thing was that now keyboard & mouse worked in plasma wayland session in multi-seat.

Could you try several times on multi-seat setup? And if you observe the issue again, then could you show the loginctl results again?

@nl6720 did you have a chance to try this?

Sorry, I didn't have the time yesterday.

Today, two times it worked fine, but the third time I triggered the issue again. This is with login then logout not by rebooting.
I got the logs while connected via SSH.

Just to note, the USB CEC adapter is now in seat-tv because I run a loginctl attach command two days ago. Here's the udev rule for reference:

==> /etc/udev/rules.d/72-seat-input-pci-0000_6a_00_0-usb-0_2_1_2.rules <==
TAG=="seat", ENV{ID_FOR_SEAT}=="input-pci-0000_6a_00_0-usb-0_2_1_2", ENV{ID_SEAT}="seat-tv

But this may not be relevant since it was there all three times I tried logging in today.

Hmm. I have no idea.
@nl6720 Could you report the issue to plasma + wayland team attaching with the link to this page? We do not know much about how they enumerate input devices. To solve the issue we need their support.
At least, I cannot find anything spurious in the journal, output of udevadm, and loginctl.

OK, let's close this here then, as this is apparently not a systemd problem, but somewhere between kde/libinput/kernel/hardware.

The issue seems to have disappeared after upgrading Plasma to 6.0.1. 🤷
