Corner switch and LED not working on Plasma 6.0.2 - Arch 6.7.1

[effeffe]

As said, the led light and corner switch ceased working after updating to plasma 6.0.1 and persists on 6.0.2

Hello,
here the situation is slightly different after update to plasma6, SUSE Tumbleweed:
corner switch still works, but the LED doesn't.

# grep touchpad /var/log/messages

tuxedo-touchpad-switch lets the kded5 start - seems to be hardcoded

ps -ef | grep kded
te        8704  7896  0 21:03 ?        00:00:00 /usr/bin/kded6
te        9015  7896  0 21:03 ?        00:00:00 /usr/bin/kded5

Could we expect an update/fix at some point?
Many thanks in advance.

Best regards, temirg.

Quick and dirty fix for led:

ENV:
HW: similar to Polaris17 Gen1 (XMG Core17 AMD, XCO17M20, Mainboard: GK7NxxR M20)
OS: SUSE tumbleweed (last updates), kernel 6.7.9-1-default
Plasma: 6.0.2

~/git-all> cp -a tuxedo-touchpad-switch tuxedo-touchpad-switch.bak
~/git-all> cd tuxedo-touchpad-switch
~/git-all/tuxedo-touchpad-switch> sed 's/kded5/kded6/g' setup-kde.cpp -i

Then the usual:

cd build
cmake ..
sudo make install
sudo reboot

Nice, thank you!

[temirg]

No problem, you're welcome.
Does my solution work for you?

[effeffe]

It works quite well ngl

For the developers, I was thinking that maybe the program should check whether kde5 or kde6 is in use, and then use the correct calls thereafter

[temirg]

Great, then I think the issue can be closed as solved.

As far as development is concerned: qt5 / plasma5 is practically obsolete,
plasma6 could survive the next 5-7 or even 10 years.

The question here is: do we still have our current notebooks after 7 years?
The effort required to adapt the code is not worth it.

But I'm not the developer of tuxedo-touchpad-switch, maybe he sees it differently. ;-)

Not all distributions have Plasma 6 yet.
And there are some that will have Plasma 5 for quite some time, like Ubuntu LTS and such.
tuxedo will likely want to support those...

But the check should be relatively simple.
The difference is just some the DBus interface names and those can be enumerated or just tried in order.
This is a minimal patch that changes only the relevant lines for Plasma 6 support: AUR/tuxedo-touchpad-switch/0001-use_kded6_instead_of_kded5.patch
It's changing only three lines...
So to additionally support kded5 you'd just need to extend the first dbus call to fall back to org.kde.kded5 if it fails to call org.kde.kded6 and remember if that happened for the second call. (Or check before the call, which interface actually exists.)

I'd do a PR, but I don't have any Plasma 5 system to test anymore...

Hi,
Also getting this issue with Tuxedo OS 3 and KDE 6.0.4, so this is not just specific to Arch.
I my case the double tap works, and I get the notification on the screen saying Touchpad On/Off
But the LED is always switched off.
Have not tried the quick fix mentioned above, I'm probably doing to wait for this to be fixed upstream.
