Changing [input] xkb_layout doesn't work and crash with added xkb_variant

[Narrat]

Hello and thanks for this project :)
But I have one problem. I cannot change the xkb_layout whatsoever.
Verified with localectl, that I have the settings I want to set:

$ localectl list-x11-keymap-layouts
(...)
de
(...)
$ localectl list-x11-keymap-variants
(...)
qwertz
(...)

After adding xkb_layout = de to the config I get this:

$ setxkbmap -print -verbose 10                            
Setting verbose level to 10
locale is C
Trying to load rules file ./rules/evdev...
Trying to load rules file /usr/share/X11/xkb/rules/evdev...
Success.
Applied rules from evdev:
rules:      evdev
model:      pc105
layout:     us
Trying to build keymap using the following components:
keycodes:   evdev+aliases(qwerty)
types:      complete
compat:     complete
symbols:    pc+us+inet(evdev)
geometry:   pc(pc105)
xkb_keymap {
	xkb_keycodes  { include "evdev+aliases(qwerty)"	};
	xkb_types     { include "complete"	};
	xkb_compat    { include "complete"	};
	xkb_symbols   { include "pc+us+inet(evdev)"	};
	xkb_geometry  { include "pc(pc105)"	};
};

Layout still being us.

And if I add xkb_variant to the config wayfire runs into a segfault:

No difference if I try this on a VT or within X11.
But as the packages aren't build with debug, it is currently missing the rest of the trace. But maybe this already helps.

Hi, setxkbmap does not work under Wayland. Unfortunately, this means you also can't check the keyboard layout in Wayfire, not until swaywm/wlr-protocols#31 gets implemented.

Anyway, your variant is incorrect which is why Wayfire crashes. We could probably handle this error though instead of crashing, but that won't fix your problem. The correct variant is just qwertz

Have you tried to actually set xkb_layout to de and type on the keyboard? I suspect it will work as you want it to (note, setxkbmap generally does not work on Wayland, so anything it reports is not trustworthy)

Ah, shoot. Good to know.

Maybe I'm missing something from your comment, but I just set xkb_variant = qwertz in the config?
And if I change it like this:

[input]
xkb_layout = de,us
xkb_variant = ,qwerty

it will fail with:

xkbcommon: ERROR: Couldn't process include statement for 'us(qwerty)'
xkbcommon: ERROR: Abandoning symbols file "(unnamed)"
xkbcommon: ERROR: Failed to compile xkb_symbols
xkbcommon: ERROR: Failed to compile keymap

Have you tried to actually set xkb_layout to de and type on the keyboard? I suspect it will work as you want it to (note, setxkbmap generally does not work on Wayland, so anything it reports is not trustworthy)

Now I'm unsure and need to recheck. IIRC I still had the english layout when typing, if I started wayfire from a VT. But I also had a missing [input] in some of these tests... Now testing it from within X11 just setting the xkb_layout to de works as expected.
Will report on that later.

[ammen99]

FWIW I just tried it, and the problem is reproducible. However, you don't need to set variant to ,querty, seems like , (probably empty as well) works fine. So try setting only xkb_layout

[Narrat]

Yes, indeed. Just setting the layout is working fine :) So, when it didn't work, it was related to the missing [input] in my config.
Thank you for your help.
Should this issue be closed or do you want to keep it around because of the reproducible error with xkb_variant?

[ammen99]

Let's keep it open. Wayfire shouldn't crash even on bad config options.
