[SOLVED][Libinput / Udev][Aorus 15P XC] Touchpad not working

Message

kukus888 · Post by **kukus888** » Tue Dec 20, 2022 10:22 pm

Hi,
After upgrading to 5.15.69 gentoo kernel, my touchpad stopped working. I tried solving it, but gave up and chose to wait for new kernel as it seemed like improperly configured kernel issue. Since then I have upgraded to 5.15.80, but the issue still prevails.

Specs
Laptop Aorus 15P XC
Kernel 5.15.80-gentoo, this time configured via genkernel
Selected profile:
[9] default/linux/amd64/17.1/desktop/plasma (stable) *
make.conf snippet:
USE contains libinput synaptics
INPUT_DEVICES="libinput synaptics"

Running
cat /proc/bus/input/devices
and manuallyfiltering the result to only show touchpad shows the touchpad is detected:

Code: Select all

I: Bus=0003 Vendor=1044 Product=7a3f Version=0111
N: Name="GIGABYTE USB-HID Keyboard Mouse"
P: Phys=usb-0000:00:14.0-11/input2
S: Sysfs=/devices/pci0000:00/0000:00:14.0/usb1/1-11/1-11:1.2/0003:1044:7A3F.0007/input/input21
U: Uniq=AP0000000003
H: Handlers=mouse2 event15 js0 
B: PROP=0
B: EV=1f
B: KEY=1f0000 0 0 0 0
B: REL=1943
B: ABS=3
B: MSC=10

So the device is detected, I figured this could be an issue in device detection, so i added separate conf file for touchpad:

Code: Select all

/ # cat /etc/X11/xorg.conf.d/10-touchpad.conf 
Section "InputClass"
        Identifier "touchpad"
        MatchProduct "GIGABYTE USB-HID Keyboard Mouse"
        Driver "libinput"
EndSection

Note: With synaptics driver, Xorg log said that Driver Synaptics cannot understand the protocol of the device, unloaded the module, and continued.

This finally made the device apparent to libinput, however the device fails(?) midway through detecting:

In full log, there is another copy of the module unloading, which i triggered by:

Code: Select all

udevadm trigger /sys/devices/pci0000:00/0000:00:14.0/usb1/1-11/1-11:1.2/0003:1044:7A3F.0007/input/input21/mouse2

Also, i tried running gentoo from live usb (Gentoo amd64 LiveGUI 20220605T17), and there, the touchpad worked without any issues, with libinput driver afaik. Copying the config files didn't help.

This is as far as i have come, this issue has been bugging me for weeks, and i don't know what to do any more. Any help would be appreciated. Thank you.

kukus888,

Welcome to Gentoo.

Please share the following.
1. The output of

Code: Select all

lspci -nnk

This will show the hardware on your PCI bus.
2. The output of

Code: Select all

lsusb

This will show what is connected to the USB bus.
Those two will fit into a post.

The output of dmesg, This is the kernel startup log.
Your kernel .config file. We might want to change this.
It may be at /proc/config.gz.
Use wgetpaste to put them onto a pastebin site and post the links.They are far too big for a post.

kukus888,

The touchpad is not on the PCI bus. I don't think its on USB either as

Code: Select all

 Bus 001 Device 006: ID 1044:7a3f Chu Yuen Enterprise Co., Ltd USB-HID Keyboard

appears to be a keyboard.

That leaves ACPI which is becoming more popular.

Code: Select all

# CONFIG_I2C_HID_ACPI is not set

is needed in your kernel if its an ACPI enumerated device.

Use the config tool of you choice to turn that option on. A module will work, then rebuild and reinstall your kernel.
Your running kernel is

Code: Select all

 [    0.000000] Linux version 5.15.80-gentoo-x86_64 (root@kukus) (x86_64-pc-linux-gnu-gcc (Gentoo 11.3.0 p4) 11.3.0, GNU ld (Gentoo 2.38 p4) 2.38) #1 SMP Tue Dec 20 21:40:39 CET 2022

The important bit there is

Code: Select all

Tue Dec 20 21:40:39 CET 2022

which is the build time of the running kernel.

After the reboot, run

Code: Select all

uname -a

and check that the running kernel is newer.

Okay, I successfully reconfigured the kernel and the touchpad works normally now. Thank you so much!
