Chromebook Touchpad driver maybe missing? supply vcc not found
by yllug from LinuxQuestions.org on (#6K2C9)
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
Abgebrochenlshw is in Version 'B.02.19.2'
What does it mean? Is lshw for the i2c interface even suitable?
