Good day!
This is a problem I’ve been having for a while now. Not sure what triggered it, but it’s even consistent across multiple arch derivatives.
Problem description:
My keyboard stops working as soon as I log into wayland session. It works fine in X11 plasma session. If I log into wayland, it no longer works in login screen until I log out from the wayland session.
However - I have another keyboard and that one works.
The keyboard that is giving me this issue: Leopold FC750R
The keyboard that remains working (but has other non-related issues): Coolermaster MK730
The keyboard seems to be recognized as USB device. This looks the same under X11 session as well - except in that session, it’s working.
The keyboard has such cable:
Using lsusb
, the keyboard is recognized as:
Bus 001 Device 005: ID 04b4:0510 Cypress Semiconductor Corp. HID Keyboard

I am using latest zen kernel. This issue has persisted for several months now and I’ve also had it appear on Manjaro + KDE/Wayland. If I recall correctly, it just stopped working from one day to the next.
I’ve already asked on Telegram and the recommendation was to ask here for more people to see.
Any pointers will be grately appreciated.
