[SOLVED] KDE no longer changes x11 keyboard settings

SunBlade · 2024-02-05 09:47:31

Hi, for a month now i noticed KDE no longer setting any x11 keyboard settings (numlock, repeat rate, layout, etc). this is starting to get annoying.

when i try to change keyboard settings in System Settings it has no effect and my systemd journal shows:

browsing the forum i noticed unnaturally many posts about keyboard issues under KDE within the past month.
did the changes in ddcutil maybe break some basic KDE stuff?

KDE *specific* ? Links?

Does the same happen for a fresh user account?

https://archlinux.org/packages/extra/x86_64/ddcutil/ is for monitor control, does the problem disappear when removing it (the keyboard might get re-attached, ie. the settings are initially applied but then lost)

KDE *specific* ? Links?

either i am going senile or i was to tired yesterday. going back through my browsing history i find only one: https://bbs.archlinux.org/viewtopic.php?id=292239
.
.

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

to force a rewrite of the config files i did:

$> sudo localectl set-x11-keymap de
$> sudo localectl set-x11-keymap de logitech_g15 nodeadkeys

but KDE still can't change keyboard settings.
.
.

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

as a temporary workaround i set the AutoRepeat defaults.

$> cat /etc/X11/xorg.conf.d/00-keyboard.conf
# Written by systemd-localed(8), read by systemd-localed and Xorg. It's
# probably wise not to edit this file manually. Use localectl(1) to
# update this file.
Section "InputClass"
        Identifier "system-keyboard"
        MatchIsKeyboard "on"
        Option "XkbLayout" "de"
        Option "XkbModel" "logitech_g15"
        Option "XkbVariant" "nodeadkeys"
        Option "AutoRepeat" "250 10"
EndSection

.
.

... does the problem disappear when removing it (the keyboard might get re-attached, ie. the settings are initially applied but then lost)

i tested my keyboard and an old one: everytime i plug in a keyboard the repeat values are reset to the x11 defaults i set above.

Does the same happen for a fresh user account?

no, a fresh user can actually change the settings in KDE. so, my user config ?breaks? KDE?
systemd journal shows the same errors when changing the keyboard settings, except the kwin_x11 error at the end is missing.
and everytime i plug in a keyboard the repeat rate is reset to the configured KDE setting.
.
which config error can break my KDE this hard?

seth · 2024-02-05 21:02:24

i find only one

That was broken HW.

everytime i plug in a keyboard the repeat values are reset to the x11 defaults i set above

Yes, that's the expected behavior; therefore the implicit suggestion of the wiki links to rely on the Xorg config instead of KDE - it's gonna be more robust wrt. flickering hardware.
What I meant by "removing it" however was ddcutil - you mentioned it, but it seems unrelated, but might screw up the USB stack(?) - so I wanted to know whether the problem exists if you remove it from your system.

However:

a fresh user can actually change the settings in KDE … which config error can break my KDE this hard?

I'd start by looking at ~/.config/kxkbrc

SunBlade · 2024-02-05 21:38:03

... so I wanted to know whether the problem exists if you remove it from your system.

$> yay -R ddcutil

:: removing ddcutil breaks dependency 'ddcutil' required by powerdevil

$> yay -R ddcutil powerdevil
checking dependencies...
error: failed to prepare transaction (could not satisfy dependencies)
:: removing powerdevil breaks dependency 'powerdevil' required by plasma-desktop
:: removing powerdevil breaks dependency 'powerdevil' required by plasma-meta

i don't think i want to remove plasma-desktop.
.
.

$> cat ~/.config/kxkbrc
[$Version]
update_info=kxkb.upd:remove-empty-lists,kxkb.upd:add-back-resetoptions,kxkb_variants.upd:split-variants

looks pretty vanilla to me, exactly like the one on my fresh user.

seth · 2024-02-05 22:06:11

"-Rd", might break powerdevil, though (if it actually links it) - why did you suspect it to be relevant?

Looks "too vanilla"?

The bugs linked there suggest that an IM (ibus, fcitx, …) might throw KDE off? Do you use anything like that?
Does your new user still work as expected after a re-login?

SunBlade · 2024-02-05 23:20:58

Does your new user still work as expected after a re-login?

yes. numlock automatically activates and repeat rate gets set by KDE.
when i switch back numlock gets turned off, and i have to press it twice to turn it back on. and repeat rate returns to the values i had set with xset.
.
.

since i have no idea what IM means, i don't think so. pacman however says i have an ibus lib installed.

$> yay -Q | grep "ibus"
lib32-libusb 1.0.26-2
libibus 1.5.29-3
libusb 1.0.26-2
libusb-compat 0.1.8-1

$> yay -Q | grep "fcitx"

"switch" means you're opening a second session, you're not logging into the user directly?
Because at that point you're likely running a second X11 server and also any kind of HW flicker from the boot/initial login (your Xorg log, https://wiki.archlinux.org/title/Xorg#General would revela such) would become irrelevant.

Also

when i switch back numlock gets turned off, and i have to press it twice to turn it back on

sounds like a VT switch and state and LED fallig apart over it.

Assuming the problem is really limited to your main user, you could poison the second user with (KDE) config files from your main user to bisect the culprit, but first you should check whether a login straight into the new user does actuall not exhibit the problem, resp. if it does, how switching to your main user behaves.

yes, but to be sure i now tested "switch" a.k.a. second session and "logout->login". i can confidently say: the sddm login screen and my fresh user both work. only my main user has problems in x11 sessions, wayland sessions work fine.

jep, by this point i am sure i messed up my config. time to spread the poison.
.
.
found the culprit: ~/.config/kded5rc
that file controls which background services get loaded at session start.
and the service in question is the System Settings > Startup and Shutdown > Background Services > Keyboard Daemon.
since the description only hints at layout switching i disabled this shortly after system installation. but it looks like this service is now used to set all keyboard configs (at least under x11).
