Bug ID: 523552
Summary: Logitech Bolt receiver keyboard becomes unusable on
Plasma Wayland after kcminputrc contains Enabled=false
for the receiver keyboard interface.
Classification: Plasma
Product: kwin
Version First 6.6.4
Reported In:
Platform: CachyOS
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: input
Assignee: [email protected]
Reporter: [email protected]

Target Milestone: ---
Created attachment 194639

I've attached the kcminputrc I had. I moved it to .bak instead of removing. In
case it's useful.
- Environment:
Plasma 6.6.4
KWin 6.6.4
Wayland
libinput 1.31.1
xkeyboard-config 2.47
linux-cachyos 7.0.5
- Hardware:
Logitech MX Keys S
Logitech Bolt Receiver (046d:c548)
- Symptoms:
Keyboard works in GRUB.
Keyboard works in LUKS.
Keyboard works in SDDM login.
After logging into Plasma Wayland:
normal keys stop working
media keys continue working
mouse continues working
evtest reports correct key events.
libinput receives keyboard events.
Only Plasma ignores normal keyboard input.
- Cause:
~/.config/kcminputrc contains:
[Libinput][1133][50504][Logitech USB Receiver]
Enabled=false
[Libinput][1133][50504][Logitech USB Receiver Consumer Control]
Enabled=true
[Libinput][1133][50504][Logitech USB Receiver Mouse]
Enabled=true
Removing the file:
mv ~/.config/kcminputrc ~/.config/kcminputrc.bak
restores keyboard functionality immediately after the next login.
- Expected behaviour:
Plasma should not disable the primary keyboard interface of the only attached
keyboard?
- Additional information:
evtest confirms the kernel produces normal events:
KEY_A
KEY_S
KEY_D
KEY_ENTER
The issue appears to be limited to the Plasma input configuration.
The keyboard became unresponsive after a first restart, after plugging it in,
with only media keys working.
It works when keyboard is plugged in after login.
This is as far as I got. Once kcminputrc, it does seem to reproduce it again,
but couldn't figure out what triggers it.
When the keyboard stops working, I do
mv ~/.config/kcminputrc ~/.config/kcminputrc.bak
and restart, then plugin the keyboard. it works until next restart. looks like
kcminputrc doesn't get created right away, so keyboard works normally until
then.
