Using keymapper to map special characters

[MrMufflon]

Hi,
I want to use keymapper to map special german characters to hotkeys. I'm struggling just to get keymapper to work at all.
I'm on Ubuntu 24.04 on X11. I tried keymapper 4.4.0 at first, but it lead to no keystrokes being forwarded at all. I had to kill the process. I then switched to 4.3.1 and now all keystrokes are forwarded, but my config is ignored. With 4.4.0 and the -v flag I saw the correct file being loaded and also the contexts where logged. With 4.3.1 only the config file is logged.
I just tried this as a config Control{O} >> "ö" in ~/.config/keymapper.conf.
Thanks,
Felix

Hi, strange that these versions behave differently. I will try them out in a VM soon.
Can you please ensure that only one keymapper and one keymapperd instance run at the same time and kill them before trying another version. Maybe they were mixed up. The new versioin should make this problem less likely.
Can your keyboard layout type an 'ö'? Did you also try some other key like Control{O} >> X? Strings with keys requiring a dead/compose keys are not implemented on Linux yet.
It should work to simulate the composition like (where Insert is the set Compose key):

Compose = Insert
Control{O} >> !Any Compose Shift{Quote} O

If layout "English (international with AltGr dead keys)" is an option, this should work:

Control{A}  >> !Any AltRight{Q}
Control{O}  >> !Any AltRight{P}

I can confirm, only one instance is running for keymapper and keymapperd. My keyboard is an english layout, so it can't type the german special characters. I tried normal characters Control{O} >> "U" with the same result. I switched back to 4.4.0 with the same behaviour, no keystrokes forwarded.
Thanks for looking into this!

I tried the Ubuntu 24.04 live version with X11 and US keyboard layout now but unfortunately could not reproduce a problem, neither with 4.4.0 nor with 4.3.1. With the compose key set to Insert and this configuration I could enter an "ö":

Compose = Insert
Control{O} >> !Any Compose Shift{Quote} O

Can you please run "sudo keymapperd -v" in one terminal and "keymapper -v" in another and post the output?

When I do sudo keymapperd -v the keyboard inputs stop working, I can't start keymapper after stat. The logs say

This lines make me curious, becaus thats my keyboard:

/dev/input/event30 grabbed (keyd virtual keyboard)

So the problem is that keyd is also running. This is currently not supported. Maybe the two programs are intercepting the inputs of each other.
