Touchpad not detected correctly, no gestures available

Q&A
1

Hello there,

recently I’ve upgraded my setup to a laptop and its touchpad doesn’t work properly and is not detected correctly as well. I’ll be glad to hear any help.

Note: this seems to happen on Clear Linux OS only, Ubuntu doesn’t have the issue and works flawlessly.

Problem description

It often accelerates and deaccelerates at random intervals causing jitters and the gesture such as two-finger scrolling doesn’t work. (Using two fingers just stops the cursor from moving, but doesn’t perform any scroll)

It is one of those “high-resolution touchpads” that those newer laptops tend to have. Unfortunately, I don’t see a way to set the touchpad to Basic.

Another effect of not being detected properly is that in GNOME Settings there are no options for Touchpad, only for mouse.

Additional Information (HW etc.)

First things first, the version of Clear Linux etc.

Current OS version: 33960
Latest server version: 33960

xinput gives out these devices:

ELAN0511:00 04F3:3041 Mouse               id=17   [slave  pointer  (2)]
ELAN0511:00 04F3:3041 Touchpad            id=18   [slave  pointer  (2)]

Disabling the Touchpad yields no effect, while disabling the Mouse disables the touchpad itself.

According to Xorg.0.log it uses the libinput driver (although it seems to be using the wrong InputClass?):

possibly it needs a proprietary firmware.
you can Google "touchpad doesn’t work on ". Usually you will find answers for Ubuntu, but what you need is to find out what’s the firmware/package you need to install

3

It’s not a proprietary firmware AFAIK, it uses the standard libinpit. The issue is I think the CL’s kernel incorrectly detects the device, since on Ubuntu it detects it normally as touchpad and everything works fine.

4

what’s the model of the laptop?

5

It’s Acer Spin SP513-52.

Editing the file /etc/modprobe.d/psmouse.conf had no effects.

can you run journalctl -k and grep anything with elan?

such as elan_i2c 5-0015: 5-0015 supply vcc not found, using dummy regulator

11

The driver for your touch pad is certainly installed

So you either sees an error like

And use modprobe to fix it.

Or you can try to write a Xorg config such as this one:
https://forums.linuxmint.com/viewtopic.php?p=1536914#p1536914

12

While in dmesg I do see messages like: note the vdd instead of vcc (also Ubuntu also gets this message, while works perfectly fine)

[    1.890515] i2c_hid i2c-ELAN0511:00: supply vdd not found, using dummy regulator
[    1.890539] i2c_hid i2c-ELAN0511:00: supply vddl not found, using dummy regulator

What do you mean by “use modprobe to fix it”? Also the Xorg config they used there uses the synaptics driver. Forcing my touchpad to use synaptics doesn’t work due to “unmatched protocol” (paraphrasing, from dmesg)

13

This bug appears on 5.4 kernel. Are you using the kernel-lts bundle?

14

Nope, I’m running the latest one.

I just recently performed a swupd update, before I was on 5.5.15-930 and it haven’t worked there.

15

On further investigation I used udevadm --attribute-walk with appropriate devices between Clear Linux (where the touchpad doesn’t work) and Ubuntu (where it works just fine). I still have no clue on how to go on fixing this.

Differences

There are differences of the assigned input[0-9]* number etc, but apart from that there’s even these:

  • Ubuntu has ATTRS{power/runtime_enabled} set to "enabled" in second to last device, while Clear Linux has it in "forbidden".
  • Ubuntu also sets ATTRS{power/control} to "auto" while Clear Linux sets it to "on"
  • Ubuntu loads the device’s driver as "hid-multitouch" while Clear Linux uses "hid-generic"
    • Ubuntu also sets the ATTRS{quirks}=="334864" while Clear Linux doesn’t have it at all
  • Ubuntu has different ATTR{capabilities/abs}, ATTR{capabilities/key} and ATTR{capabilities/msc}, alongside with ATTR{properties}

Below I’m attaching the outputs of udevadm from both systems.

Clear Linux udevadm output

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

How about this?

Also someone suggest to disable hid-over-i2c in BIOS

17

The thing is that the touchpad does work, but has constant acceleration issues, is detected as a mouse (thus GNOME doesn’t has the touchpad settings) and two-finger scroll doesn’t work.

Unfortunately, I don’t have such option in BIOS.

18

can you try the other sections in the guide

19

I’ve already done so beforehand with no success, unfortunately.

20

Okay, I’ve finally solved the issue. The fix was simple and dumb because it was my fault. For that, I’d like to apologize for the time wasted.

My Clear Linux setup was previously installed on a different PC, which required some workarounds to get working. Those workarounds did not work on the new PC. Basically, I had blacklisted the hid_multitouch, which was required for the touchpad. After I whitelisted the module again, lo and behold it became working again.

Again, sorry for all the time wasted and thank you for all the efforts for help.
