SUMMARY When attempting to log into KDE Plasma x11 session using an external keyboard connected to my laptop, I am immediately returned to the login screen. This condition will loop until the external keyboard is removed. Logging in with laptop keyboard works as expected. Logging in with Wayland using the external keyboard also works as expected. STEPS TO REPRODUCE 1. connect external keyboard to laptop 2. attempt to login to the x11 desktop 3. note that you are returned to the login screen OBSERVED RESULT returned to the login screen after inputting correct password EXPECTED RESULT logged into desktop (x11 session) SOFTWARE/OS VERSIONS (available in the Info Center app, or by running `kinfo` in a terminal window) Linux/KDE Plasma: Fedora Linux 42 KDE Plasma Version: 6.3.4 KDE Frameworks Version: 6.13.0 Qt Version: 6.9.0 ADDITIONAL INFORMATION This only occurs when attempting to use an external keyboard to log into an x11 session.
Moved from plasma-login to plasmashell. --------- System log output during a failed login would be useful. You can collect this by noting the time just before logging in, and the time just after you get sent back to the login screen. With these times, you can get the relevant logs using the command: journalctl --since "17:00:00" --until "17:00:30" > log.txt for instance, for between 5 PM and 5PM + 30 s. Alternatively, you could use: journalctl -f > log.txt in a separate TTY, switching back, attempting login, and then switching to that TTY to interrupt it after login fails. Both will yield a file, 'log.txt' which contains the system log and can be attached here, and we can look at it to try to determine why login is failing.

Additionally, on further testing it seems that the problem only manifests when i have my mouse wireless dongle and the external keyboard connected at the same time. Whereas individually, they work fine.
I don't believe the log output indicates an issue in Plasma. It seems like it could be an SDDM issue, possibly https://github.com/sddm/sddm/issues/2043. It might be worth taking this to Fedora.
