Bug ID: 485362
Summary: Modifying kxkbrc configuration through the command
line is not user friendly
Classification: Plasma
Product: kwin
Version: 6.0.2
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: input
Assignee: kwin-bugs-n...@kde.org
Reporter: bojidar.marinov...@gmail.com
Target Milestone: ---
SUMMARY
Currently, changing `kxkbrc` through the command line via `kwriteconfig`
results in no observable changes until the configuration is manually changed
through the settings module.
Looking through the source code, I managed to get Kxkb/Kwin to reload the
configuration through `dbus-send --session --type=signal
--dest=org.kde.keyboard /Layouts org.kde.keyboard.reloadConfig`, but this was a
pain to figure out. Ideally, KWin could listen for config changes to `kxkbrc`
using `KConfigWatcher`, and eliminate the whole need for sending that
`reloadConfig` signal; though I would be willing to settle for better
documentation.
Why it matters? - Being able to change settings from the command line enables a
larger variety of usecases, integrations, and extensions than KDE developers
could have possibly planned out beforehand. This gives users more freedom and
power than merely being able to modify the source code, as they can now modify
the system's behavior without having to recompile it at all.
STEPS TO REPRODUCE
1. Run `cat .config/kxkbrc`, observe the current values of the configuration.
2. Run e.g., `kwriteconfig6 --file kxkbrc --group Layout --key Options
caps:backspace`, which would make Caps an additional backspace.
3. Run `cat .config/kxkbrc`, observe that the configuration has been changed.
OBSERVED RESULT
Pressing CapsLock is still not as an additional backspace.
The configuration was not applied, and there is no documentation which would
give a clue as to why.
EXPECTED RESULT
The configuration is applied as soon as it's changed through kwriteconfig6 OR
there is an extra command that has to be run which is documented somewhere.
Pressing CapsLock functions as an additional backspace.
WORKAROUND
Run `dbus-send --session --type=signal --dest=org.kde.keyboard /Layouts
org.kde.keyboard.reloadConfig` OR open the keyboard settings module and change
some value back and forth to update the configuration
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch Linux
KDE Plasma Version: 6.0.2
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.2
ADDITIONAL INFORMATION
Vaguely related to bug 470470, as I wouldn't have ran into this issue if
`setxkbmap` was working for my usecase (quickly switching the keyboard model
between DreymaR's pc104awide model and the default pc104 model).
