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.

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

ps -ef | grep kded

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

[effeffe]

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 going to wait for this to be fixed upstream.

Hi,
In my last comment above, I mentioned that only the led stopped working, but double tapping worked.
But now that is not the case. Double tapping the corner does not work any more either, so there is no way to turn of the touchpad without fiddling around with the settings. Something definitely happens when double tapping, it does show Touchpad Off for a split second, but then shows back Touchpad On automatically.
I'm using an up to date Tuxedo OS 4 with KDE 6.2.3.

I have the Infinitybook Pro 16 gen 8 (MK2)

Same is true for Tuxedo OS. The corner works, plasma has a small message but the light does not toggle.

I see the same behavior and I am still in touch with Tuxedo support about it. It looks like KDE6 removed a lot of dbus methods the touchpad-switch is relying on:

tuxedo-touchpad-switch/setup-kde.cpp

Lines 171 to 181 in 6f3ee2f

	kded_modules_touchpad = g_dbus_proxy_new_for_bus_sync(G_BUS_TYPE_SESSION,
	G_DBUS_PROXY_FLAGS_NONE, NULL,
	"org.kde.kded6",
	"/modules/kded_touchpad",
	"org.kde.touchpad",
	NULL, NULL);
	// call a random method to check if object exists
	GVariant *isMousePluggedInParam = g_dbus_proxy_call_sync(kded_modules_touchpad,
	"isMousePluggedIn",
	NULL, G_DBUS_CALL_FLAGS_NONE,
	G_MAXINT, NULL, NULL);

In these lines it seems to be only "a random method to check if object exists", but it is called again later here

tuxedo-touchpad-switch/setup-kde.cpp

Line 57 in 6f3ee2f

GVariant *isMousePluggedInParam = g_dbus_proxy_call_sync(proxy, "isMousePluggedIn", NULL, G_DBUS_CALL_FLAGS_NONE, G_MAXINT, NULL, NULL);

But in KDE6 there is no "isMousePluggedIn" method and I am unsure where it is in kde6.

Using qdbus, I was only able to find these methods (not sure whether this is the full list, I am far from an expert with dbus!):

$ qdbus "org.kde.kded6" /modules/kded_touchpad
signal void org.kde.touchpad.enabledChanged(bool)

method bool org.kde.touchpad.isEnabled()
method Q_NOREPLY void org.kde.touchpad.toggle()

method QString org.freedesktop.DBus.Introspectable.Introspect()
method QString org.freedesktop.DBus.Peer.GetMachineId()
method void org.freedesktop.DBus.Peer.Ping()

Edit: https://bugs.kde.org/show_bug.cgi?id=415364 there are some new methods that might need to be used instead, see
