Dear Helpers,

The TrackBall, TouchPad and ClickPad ( X201 ThinkPad ):



Distribution: KDE Neon 5.12
uname: Linux x4 4.13.0-38-generic x86_64 x86_64 x86_64 GNU/Linux

Suddenly, all of these inputs just stopped working, but keyboard. ( Might be after kernel update: apt full-upgrade )
Checked the log and there were some lines like (some lines with psmouse I couldn't copy):

Code: Select all

...
psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1
psmouse serio1: synaptics: Unable to query device.
...

I've tried to reboot. Nothing changed.
Then, I've remounted buses of TouchPad and TrackBall in case of contacts' losse. Nothing chagned.

Tried to reset the driver via: "modprobe -r psmouse; modprobe psmouse;". TouchPad started working, but TrackBall and Buttons didn't.
Then, I've tried to boot into previous kernel 4.13.0-37 and now work TrackBall, TouchPad and Button above TouchPad work, but Buttons below TouchPad don't.

Please, what could it be, why ? How to fix all inputs ?
Thank you, really.

Best regards,

The error message seems to unrelated to anything in the components developed by KDE. This is confirmed by the fact that something changed with the previous kernel.
All the input driver stack is linked to the synaptics or the libinput driver, and it is only used by Plasma and other components.

In the question by VeVen:

Suddenly, all of these inputs just stopped working, but keyboard.

That could be interpreted as, suddenly after Linux was installed, or, suddenly after an update was installed.

In any case, perhaps you know that it is a fairly common experience in the Linux world that esp. inexpensive laptops often have "anti-linux" features in them--in one case it can be bluetooth, another it can be display background light control, and so on: and it can be a question of luck whether to get this or that Linux to run on it. For older (popular) laptops, Linux folks have often managed to figure out how to solve it. Early today I installed a Linux on a shop-new inexpensive Asus laptop and after two minutes the Touchpad didn't work and if I tried to use it then, even an USB mouse wouldn't work. I tried all the tricks in the book--also tried Ubuntu--but only a full reboot would restart the touchpad. So I turned the touchpad off in the Bios at startup. And as I never use Touchpad in any case, only real mouse pointers, I don't mind. It has Neon with Wayland on it now, with USB mouse, and has now worked superbly well for hours.
