As the title says I have an issue with the touchpad of my laptop.
This has been an issue for a very long and I have so far only found a workaround. Originally I had started on this device with Ubuntu, where the issue also was present.
The touchpad can work when performing a force shutdown while the laptop is suspended. I you then reboot it’s gets detected
I am on kernel 5.15
Here’s what I know:
Touchpad:
MSFT0001:00 04F3:3140
I does not show up anywhere (libinput, xinput, lshw, etc) except for some reason in xournalpp, though not functional and these two directories:
/sys/devices/platform/AMDI0010:03/i2c-1/i2c-MSFT0001:00
/sys/bus/i2c/devices/i2c-MSFT0001:00
Binding it to a driver seems not to be possible:
echo "i2c-MSFT0001:00" | sudo tee /sys/bus/hid/drivers/hid-generic/bind
i2c-MSFT0001:00
tee: /sys/bus/hid/drivers/hid-generic/bind: No such device
I also tried i2c_hid_acpi, as this is the driver it gets bound to when working.
This is the message I can see in dmesg when it gets detected

This when it does not:

I appreciate any help. Tell me if you need more info.
