GDM USB keyboard input not working after update

Hi hope someone can help,

This morning I updated all packages via "pacman -Syu" and found after rebooting that I couldn't type anything at login / gdm (or even drop back to fallback shell)

After disabling gdm via systemd.mask I validated that the non graphical shell worked as expected and also that lightdm worked fine to launch into gnome shell (from their everything is ok)

So my issue seems to revolve around the newest gdm.... Anyone seen issues like this lately?

pacman -Qs ibus

Also test https://wiki.archlinux.org/title/GDM#Use_Xorg_backend and please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

Re: GDM USB keyboard input not working after update

Got the same issue.
My workaround is to switch to a new terminal session from GDM (Ctrl + Alt + F2), then come back to GDM session (Ctrl + Alt + F1). Then keyboard is working

➜  ~ pacman -Qs ibus
local/hidapi 0.14.0-1
    Simple library for communicating with USB and Bluetooth HID devices
local/libgusb 0.4.6-1
    GObject wrapper for libusb1
local/libibus 1.5.28-4
    IBus support library
local/libusb 1.0.26-2
    Library that provides generic access to USB devices
local/libusbmuxd 2.0.2-3
    Client library to multiplex connections from and to iOS devices

Boot systemd journal : http://0x0.st/H1A8.txt

This looks like a related problem and comes from some™ config file.

grep -r event8 /{etc,usr/share}/X11/xorg.conf*

Jul 03 18:50:23 archdesktop /usr/lib/gdm-x-session[1699]: (**) Option "Xinerama" "0"

Regardless of the above result, get rid of /etc/X11/xorg.conf - it's nvidia-settings generated garbage and will at best occlude issues.
