SUMMARY When I plug a new keyboard in KDE the disposition configured in ibus is reset. I guess it is a conflict with KDE that tries to reset the configuration and does not see that it was overwritten by ibus, as ibus still thinks that it is using the old distribution. I'm not sure which side is faulty (should ibus disable KDE's keyboard or KDE avoid changing the keyboard…), so I will report it in both (see https://github.com/ibus/ibus/issues/2446). STEPS TO REPRODUCE 1. Choose multiple configurations in ibus in KDE 2. Plug a new keyboard OBSERVED RESULT Observe that the keyboard is reset EXPECTED RESULT I expect the keyboard layout not to change SOFTWARE/OS VERSIONS Linux/KDE Plasma: NixOs unstable (1ffba9f2f68) KDE Plasma Version: 5.24.4 KDE Frameworks Version: 5.92.0 Qt Version: 5.15.3 ADDITIONAL INFORMATION See also https://github.com/ibus/ibus/issues/2446 and https://github.com/ibus/ibus/issues/2446
