newbie post. need help with touchpad

[lf84217]

I'm new to gentoo, just installed on a new Thinkpad Carbon X1 laptop.

I am having a hard time getting my synaptics touchpad to work.

I used genkernel for the initial kernel config. I've followed all the instructions in https://wiki.gentoo.org/wiki/Synaptics, still no luck. I also enabled all synaptics options in kernel and recompiled.

My output from lsusb is this:

Code: Select all

Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 004: ID 174f:2454 Syntek Integrated Camera

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Would be grateful if someone could help me with this issue.

lf84217,

Welcome to Gentoo.

We are all new to Gentoo. Just as you think you are getting the hang of it, it changes under you :)

Code: Select all

Bus 003 Device 003: ID 06cb:00fc Synaptics, Inc.

looks like your touchpad.
The Arch Wiki says it works, so its a configuration issue.

Where does it not work?
You need separate drivers for the console and GUI, so it can work in one but not the other.

Make friends with wgetpaste and pastebin thee things.

1. the output of

Code: Select all

emerge --info 

so that we can see your gentoo configuration.
2. The output of dmesg, so we can see what the kernel did as it started.
3. Your kernel .config file, in case we need to suggest some changes.

Whole logs are important. What's missing but should be there is as important as what is actually present.
Filtered logs stop helpers spotting missing things.

Thanks!
I am sshing in from another laptop, so I can just copy paste directly.

I am not able to access the touchpad when using X with KDE plasma.
Currently I am not able to get startx working as regular user, so have to run startx as root. Also having a hard time getting X to start after boot, but going to deal with that after I figure out the touchpad issue.

lf84217,

Code: Select all

ACCEPT_LICENSE="*"

That's nasty. You might not want at accept the Gates Private License (GPL) without reading it.

Code: Select all

INPUT_DEVICES="libinput synaptics"  

Thats OK.
The rest of emerge --info is "mostly harmless"

Looking at dmesg, you have 8 threads and 16GB RAM, so

Code: Select all

MAKEOPTS="-j4"

is conservative.
There is nothing wrong with that.

Code: Select all

Looks OK.

Is for a trackpad connected over PS/2. That's not you but there is noting wrong with having several touchpads connected.

Turn on

Code: Select all

# CONFIG_I2C_HID_ACPI is not set

in your kernel, do the rebuild and reinstall dance.
At first sight, that does not appear to be needed as your touchpad appears on the USB bus ... but its not detected.
Read for hints on using menuconfig.

When you reboot, make sure that your kernel is newer than

Code: Select all

 [    0.000000] Linux version 5.15.52-gentoo-x86_64 (root@tux) (gcc (Gentoo 11.3.0 p4) 11.3.0, GNU ld (Gentoo 2.37_p1 p2) 2.37) #4 SMP Tue Jul 26 04:02:10 EDT 2022

Thats the build date and time of the running kernel. Its always good to check that you are running the kernel you think you are.

Thanks so much!

You saved me from giving up and installing Ubuntu.

That was precisely the issue, and touchpad is working now.
