Description Tobias Bora 2024-03-04 16:31:43 UTC 
SUMMARY

If I enable "swap Ctrl and caps lock", both keys are turned into Caps lock instead of being swapped.

STEPS TO REPRODUCE
1. Go to keyboard > advanced > Ctrl position and enable "swap Ctrl and caps lock".

Screenshots available in https://github.com/NixOS/nixpkgs/issues/293278#issuecomment-1976938917

OBSERVED RESULT

Observe that now both CTRL (left) and caps lock are mapped to caps lock key, instead of being swapped. setxkbmap, on the other hand, does not have this issue (but first, make sure to type `setxkbmap us` or alike, otherwise KDE will still be used as the input system).

EXPECTED RESULT

I would expect caps to be a ctrl key, not a caps key anymore.

Is it still happening in Plasma 6?
Comment 2 Tobias Bora 2024-03-06 02:40:53 UTC 
I can confirm that the bug is also present in plasma 6… but it is in fact more subtle than I was thinking: the behavior is correct for the azerty layout… but not for the BEPO AFNOR layout. So just changing the layout between azerty or bepo would trigger the bug.

forgot to change the status
Comment 4 Tobias Bora 2024-03-06 02:44:06 UTC 
Also, note that plasma 6 has many bugs, notably related to shortcuts. For instance, typing Ctrl + alt + T would not start Konsole, Fn + sound would not change the volume… and the volume applet is actually even completely gone from the systray (at least in NixOs). So I will switch back to plasma 5, and use a workaround I found: if I enable ibus input system, then it works as expected.
