[SOLVED] Chromebook Touchpad driver maybe missing? supply vcc not found

yllug · 03-03-2024, 01:06 PM

I've installed Void Linux on my chromebook - for learning purposes.
Dell Chromebook 3100

Without any further driver installation, it works quite well.

in general, I wonder if there is a good way to check if suitable drivers are already installed for each device?

How can I determine the manufacturer and device ID of the hardware components for which the drivers may be missing?

In particular, I have the following problem:

The touchpad generally works - but not well. On the old Chromeos, the touchpad worked very well. But now it's necessary to press large areas of my fingers on the touchpad for it to work at all. If I try to use the touchpad with my fingertips, nothing happens. I hope that installing/replace drivers will improve this behaviour.

It seems to be an Elan Touchpad. Dmesg prints the following messages for 'elan':

Code:

elan_i2c i2c-ELAN0000:00: supply vcc not found, using dummy regulator
elan_i2c i2c-ELAN0000:00: Elan Touchpad: Module ID: 0x00b7, Firmware: 0x0006, Sample: 0x0009, IAP: 0x000e

I tried to install lshw to get hardware information, w/o success. when i run it, it prints:

Code:

terminate called after throwing an instance of 'std::length_error'
  what():  basic_string::_M_create
Abgebrochen

lshw is in Version 'B.02.19.2'

What does it mean? Is lshw for the i2c interface even suitable?

See if you have libinput installed on your chromebook. I did not install Void on Dell Chromebook II. I run this instead

Even though my cats knocked it off the table. It still works OK. My touchpad works good.
lshw, pinxi, inxi, there are no problems on mine.

libinput seems already to be installed in version 1.25.0

Well. In my other threads shown in that link. I show I edit the touchpad on mine.

Hm. Unfortunately, I can't make heads or tails of your threads. Do these threads fit at all? I saw that they are about synaptics.

I have now installed antix instead, and it works flawlessly. Even the speakers work (I realized afterwards that this didn't work either).

Antix looks interesting. Many thanks for the tip.

I even modified the system a little. I wanted the laptop to show me the session exit options menu when I press the power button. Natively, the laptop shuts down in this case. This is a bit dangerous because I am used to having the Del key at this position.

I found out in the shellscript /etc/acpi/powerbtn-acpi-support.sh that the script /etc/acpi/powerbtn.sh is called (if exists) instead of shutting down the laptop.

Since the file did not exist, I created it and wrote the following into it:

Code:

#!/bin/sh
(
	flock -9 || exit 1
	PATH=$PATH:~/usr/local/bin
	su -c 'DISPLAY=:0 python3 /usr/local/lib/desktop-session/desktop-session-exit.py' g
) 9>/var/lock/acpishutdownlock

This now leads to the session-exit-menu being displayed instead of the machine shutting down directly.

Do you think I should open a new thread for my amazing script?
