Touchpad and trackpoint no longer working after reattaching convertible keyboard

English Hardware
1

I have Tumbleweed running on a lenovo thinkpad helix, which is a convertible with a detachable keyboard. The keyboard has both a trackpoint and a touchpad. Up to about a week ago the trackpoint and touchpad worked fine with detaching and reattaching the keyboard.

Now, upon booting both trackpoint and touchpad work, but after detaching and reattaching the keyboard neither trackpoint nor touchpad work any longer. They keyboard still works after reattaching.

Here is the output for ‘xinput list’

My only idea is that the driver is not being reloaded when the keyboard is reattached, but I cannot find which module might need reloading. In yast hardware info, both Synaptics TM3075-002 and TPPS/2 IBM TrackPoint show up but neither of them have a driver listed. The driver for the keyboard is usbhid, but trying ‘modprobe usbhid’ does not restore the trackpoint and touchpad.

This does not appear to be an issue with the hardware, since detaching and reattaching the keyboard still works fine in Windows.

Any pointers regarding what might be going on and how to fix it would be greatly appreciated.

Does this behaviour happen regardless of the USB port used? I notice you’ve attached it to a USB 3 port from the output you have posted. Try a USB 2 port (if available) for test purposes.

Following a reconnection of the ITE device, what is reported by the following?

/usr/sbin/hwinfo --mouse

What is reported at an Xorg level? You could watch the tail of Xorg.0.log…

tail -f /var/log/Xorg.0.log

…then reconnect and observe.

The tablet has a dedicated port which plugs into the keyboard dock, it doesn’t plug into a usb port. The keyboard dock itself has a usb 3 port. I am using the “ultrabook” keyboard, for reference you can see some pictures here https://www.pcmag.com/feature/336727/lenovo-thinkpad-helix-2nd-gen
So there is no choice in terms of what to plug the keyboard in.

/usr/sbin/hwinfo --mouse

output:

tail -f /var/log/Xorg.0.log

had some interesting information. It showed the touchpad and trackpoint as events 18 and 21 respectively, before detaching, but these events do not show up again after reattaching.

Unfortunately, I somehow managed to shut down the server, so that I cannot copy any content from the log.

I think what did this was uninstalling the x86-libinputj package. The Xorg log showed that libinput is what takes care of registering devices. I had previously uninstalled libinput because the trackpoint is so stiff even at the most sensitive setting (that I have been able to work out). Instead I had been using xinput to set the trackpoint sensitivity, which worked much better. A recent update must have reinstalled libinput, so I tried unistalling again, and since then the tail of the Xorg log shows the above, and the file has not been modifed since then.

xinput enable "TPPS/2 IBM TrackPoint"

does not do anything after the keyboard is reattached, though disabling and enabling with xinput work before the keyboard is detached.

A regular usb mouse attached to the usb 3 port on the keyboard dock works as expected when plugged in.

I also have a thinkpad usb keyboard with a trackpoint. The trackpoint on that also works fine when plugged into the usb port on the keyboard dock. Even when I detach the tablet from the dock and reattach the trackpoint on the usb keyboard works.

The hwinfo output looks as expected. Let’s see which Xorg input driver is handling the devices from boot

grep "Using input driver" /var/log/Xorg.0.log

and for a complete picture please confirm which Xorg input driver packages you have installed

zypper se -si xf86-input

The libinput driver is replacing both the evdev and synaptics drivers, but for some input devices the legacy drivers still offer better support. In fact Xorg can be configured to use a particular driver for a given device if necessary.

grep "Using input driver" .local/xorg/Xorg.0.log

gives the following. This seems to be where the xorg log is now, the one in /var/log has not been modified since yesterday.

From what I understand evdev just ‘forgets’ about the trackpoint, though when reattaching something is configured as a mouse, while synaptics does not get called on again to reload the touchpad.

6

This is the case when Gnome is running as Xorg runs non-root.

Just wondering - Did this loss of the traackpoint device also occur when using libinput?

I also wonder whether the kernel driver is binding to the wrong device somehow.

though when reattaching something is configured as a mouse, while synaptics does not get called on again to reload the touchpad.

I recall a recent kernel bug that may be at play here. I’ll see if I can dig out the details.

Found it, but not sure that it is relevant to what’s going on here…

That’s good to know. I am trying out gnome since touch actions have become completely unusable in kde/qt (lifting a finger off the screen does not register as a button release, so any kind of click action is next to impossible now - as a bonus autorotate works in gnome), at least on this device.

Just wondering - Did this loss of the trackpoint device also occur when using libinput?

Yes. Just to make sure, and for good measure, I reinstalled xf86-input-libinput and uninstalled xf86-input-synaptics and xf86-input-evdev.

so both trackpoint and touchpad are recognised after boot, but they never come up again in the xorg log.

I recall a recent kernel bug that may be at play here. I’ll see if I can dig out the details.

Given that my problem occurs even without synaptics installed, it would seem not. However I have had some of the same problems with mentioned in that bug, so that is good to keep an eye on.

9

Since this problem occurs with either libinput, or evdev+synaptics, it would seem that the problem is not with them but something else. What else could that be? Xorg? What else might be responsible for recognising hotplugged peripherals? udev?

10

It does seem to be kernel related from what you’ve posted so far. You could watch/capture the kernel output when the reattaching the problem device.

dmesg -w
11

Yes, that was the clue I needed! I downgraded the kernel to version 4.11.7 from the current TW kernel, and reattaching the keyboard now works as expected. I’ll file a bug report, and keep this older kernel until it gets fixed.

Many thanks for your help!

Glad to have been of assistance. Post a link to the bug report so that others who come searching can easily find it.
