Since Anh-Linh 25.0.1 Update: Mouse(s) not working

Support System Updates
1

Hi there, not sure if this is really the right category.

Since the last update, my Thinkpad T14 AMD will not use external mouses anymore.

USB connected to Dock (40AJ): USB Device present, no Input, no category to select mouse in the options.

lsusb after connecting the mouse:

Bus 004 Device 046: ID 04d9:a067 Holtek Semiconductor, Inc. USB Gaming Mouse

USB connected directly to laptop: Same.Bluetooth Mouse connected: Mouse being shown in BT settings, but also no input and not selectable in the settings.

My system:

Operating System: Manjaro Linux
KDE Plasma Version: 6.5.4
KDE Frameworks Version: 6.20.0
Qt Version: 6.10.1
Kernel Version: 6.12.61-1-MANJARO (64-bit)
Graphics Platform: Wayland
Processors: 16 Ă— AMD Ryzen 7 PRO 4750U with Radeon Graphics
Memory: 16 GiB of RAM (14.9 GiB usable)
Graphics Processor: AMD Radeon Graphics

After the update of December 10th, the dock also had major problems (No displays, no charging, but USB hub connected successfully, these have been resolved by disconnecting and repowering the dock.

Let me know if there is any more info that might be relevant. Thank you :slight_smile:

Hi @Wasserburg, and welcome!

In order for us, or anyone for that matter, to be able to provide assistance, more information is necessary. To that end, please see:

inxi --filter --verbosity=8 --color=0

Please also note and heed: Forum Rules - Manjaro

Those with privacy concerns: note that when -z, or --filter is used, all personally identifiable information is filtered out from the resulting inxi output. :eyes:

Hope you manage!

:bangbang: Tip for legibility: :bangbang:

To provide terminal output, copy the text you wish to share, and paste it here, surrounded by three (3) backticks, a.k.a grave accents. Like this:

```
pasted text
```

Or three (3) tilde signs, like this:

~~~
pasted text
~~~

This will just cause it to be rendered like this:

Portaest sed
elementum
cursus nisl nisi
hendrerit ac quis
sit
adipiscing
tortor sit leo commodo.

Instead of like this:

Portaest sed elementum cursus nisl nisi hendrerit ac quis sit adipiscing tortor sit leo commodo.

Alternatively, paste the text you wish to format as terminal output, select all pasted text, and click the </> button on the taskbar. This will indent the whole pasted section with one TAB, causing it to render the same way as described above.

Thereby improving legibility and making it much easier for those trying to be of assistance.

:bangbang::bangbang: Additionally

If your language isn’t English, please prepend any and all terminal commands with LC_ALL=C. For example:

LC_ALL=C bluetoothctl

This will just cause the terminal output to be in English, making it easier to understand and debug.

Please edit your post accordingly.

Note that the above text is partially pre-prepared as a general introduction for new forum users. Please take the time to follow links given and learn how to create effective support requests and encourage quality responses.

As you are using Plasma - know that Plasma can act weird after updates.

This can be caused by local cache files and local configurations.

First try clearing your local cache

rm -rf ~/.cache/*

Another place is runtime configuration files ~/.config/*rc and ~/.local/state/*rc.

A third option is a reset of Plasma’s configuration files but which one is causing your issues is next to impossible to guess.

I use a ThinkPad X13 Gen4 AMD - no docking - no external mouse - so there is that - but I have no issues with the hardware and the Plasma running on top of it.

Additionally, this should be done in a TTY whilst logged-out of Plasma otherwise it’ll be “in use”. :wink:

Hello and thank you for the suggestions! Would the deletion of KDE/Plasma relevant caches suffice? Deleting the entire .cache seems like an arduous choice, considering all the involved programs folders.

The cache will be recreated - no worries - it is a safe operation - but you can do as you see fit.

Deleting everything in it would be easiest, as:

  • I don’t know which directories in it is for plasma and related; and
  • It will get rebuilt transparently, automatically and silently in the background as you use your computer, just like it was built the first time.

Thank you both again for the explanation. I confused the cache with the settings.
I just booted my thinkpad to delete the cache and: The mouse(s) work again. I haven’t touched a single file yet. I guess my KDE figured it out :wink:
