Touchpad doesent work over i2c-hid

dariolol · 2021-06-09 20:06:59

Hi, i own a Chuwi Lapbook Pro.
Everything works, except the touchpad.
The touchpad works randomly, sometimes it works everything and sometimes not.
When i start the PC and i notice that the touchpad doesent work, i remove i2c-hid module and add it again.
Once the touchpad started working, it work until i shutdown my pc.
Its a HTIX 5288 and on the official forum (https://forum.chuwi.com/t/fix-linux-tou … 5288/23365) someone posted a systemd service to check if the touchpad is dead and reload it, but its just a workaround. Any ideas?

I have the same problem on an Acer Spin 713 aka (CP713-2W). Removing the i2c_hid_acpi kernel module and reloading activates the touchscreen. But I still get errors in the kernel log. Here's the relevant output:

1. please use code tags, https://bbs.archlinux.org/help.php#bbcode
2. the OP does explicitly not use an elantech touchpad
3. did you see https://wiki.archlinux.org/title/Laptop#Elantech ?
4. there're no errors *after* relading the module and the ones before the module and the ones before explain the status quo.
5. https://bugzilla.kernel.org/show_bug.cgi?id=207759 - seems elants_i2c steals the device.
