Touchpad stucked

#1 Post by fch »

I have this small bug that happens after a boot or reboot every now and then. The cursor gets stucked and does not move, I always try to unlock it with f10 on my notebook, but nothing happens. What solves it, is force reboot then perform a ctrl+alt+esc+power button, wait for the red power light to blink then it boots and touchpad mouse works again.
My hardware is a starlabs labtop mkIII

Try "lsusb -k" to see what driver it's using, then try unloading and unloading the module (driver) manually to see it that can unstick it.
You may have to learn how to open a terminal with keyboard only to do that, though.

Is usbutils installed?

-k is not a valid option with lsusb

It was not installed, now it is, should I perform a --verbose and share the output?

Are you sure the touchpad is a USB device ? Most laptops I have seen had a PS/2 touchpad.

I am sure it is not a device connect on a USB port but a normal touchpad, like any laptop.

There is no such thing as a "normal touchpad". Integrated devices may have an internal USB connection. This is rather common among integrated SD card readers, wireless or bluetooth adapters.

For instance in my laptop, the integrated fingerprint reader and bluetooth adapter have USB connections :

Code: Select all

Bus 003 Device 002: ID 0483:2016 STMicroelectronics Fingerprint Reader
Bus 003 Device 003: ID 0a5c:201e Broadcom Corp. IBM Integrated Bluetooth IV
You can check in the kernel log (as root) how your touchpad is connected :

Code: Select all

dmesg | grep -i touchpad

It looks like the touchpad has an I2C connection. I don't know much about it.
