[SOLVED] Dead keys not working on Plasma Wayland

sosonok · 2024-04-12 09:48:57

Dead keys don't work in Plasma Wayland. It happens with Qt applications in general, with LibreOffice, with Telegram... However they work in Firefox, Typora, Brave, Spotify, Obsidian...

It used to work fine, but I don't know if the problems started with the move to Plasma 6 (and Wayland) or later.

as far as i know if you use wayland you need to change keyboard layout in -> Plasma Settings - Keyboard

sosonok · 2024-04-12 14:37:34

Yes, my language and layout are set there, too (same as before upgrading to Plasma 6 / Wayland).

Have you been running plasma 5 on wayland or X11?

locale is C

localectl

The dead_keys themselve are part of the keyboard layout (no idea how to test for that on kwin_wayland, xev is proably insignificant …) but the dead key composition is locale dependent.
When you enter "`", does that immediately print the glyph or can you just not get to à this way (ie. `+a just prints a)?

sosonok · 2024-04-12 20:32:16

Hi, seth.

Yes, I've been running Plasma 5 on X11.
When I press "´" nothing happens, so yes: ´+a just prints a.

seth · 2024-04-12 21:51:27

So the keymap is correct but the composition doesn't work what makes you locale settings very relevant.

localectl
locale
locale -a

Or it could just be a plasma/wayland bug

sosonok · 2024-04-13 05:05:42

Here it goes:

localectl 
System Locale: LANG=es_ES.UTF.8
    VC Keymap: es
   X11 Layout: es

Ok, so the locale is completely unsuspicious.

Are you using a limited IM?
https://wiki.archlinux.org/title/Input_method

printenv | grep -E '(_IM|XMOD)'

I assume they work for Plasma/X11?
There's https://www.reddit.com/r/kde/comments/1 … t_working/
Does it help to

export XCOMPOSEFILE=/usr/share/X11/locale/es_ES.UTF-8/Compose

https://wiki.archlinux.org/title/Xorg/K … ompose_key

For

Qt applications in general, with LibreOffice, with Telegram... However they work in Firefox, Typora, Brave, Spotify, Obsidian

the most likely scenario is that gtk just uses ibus and side-steps the XIM failure (LibreOffice isn't exactly a Qt client) and exporting "GTK_IM_MODULE=xim" to them makes them fail on deadkeys likewise?

sosonok · 2024-04-13 15:12:37

Well... I'll try to keep it short...

Apparently I didn't have any input method configured / installed (is that possible?). The thing is that

printenv | grep -E '(_IM|XMOD)'

didn't return any result, so I installed ibus and configured it from Plasma Systemsettings, and now it works. So I've probably been using KDE like this for months and didn't notice it before because I don't usually write in Spanish in any of the affected applications.

But now I'm curious... I noticed that there is no such directory in my system:

/usr/share/X11/locale/es_ES.UTF-8/

Anyway, I'm marking the thread as solved. Thank you very much for your help.

seth · 2024-04-13 15:34:20

There indeed isn't a spanish locale in https://archlinux.org/packages/extra/x86_64/libx11/
The default US Compose map would (still) provide that, so my theory is that w/o ~/.XCompose or XCOMPOSEFILE X1 just falls back to the US variant but plasma/wayland doesn't?

(If you're curious and since you've the locale installed … AHHHHHHH

LANG=es_ES.UTF.8

isn't a valid locale!
es_ES.UTF-8 is!
So your locale was broken all along.

sosonok · 2024-04-14 06:27:15

:facepalm:
Now it is really solved.
Thanks again.
