[Solved] Dell Laptop touchpad going crazy after resume from hibernate

My Dell Precision 7760's touchpad is malfunctioning after waking from hibernate.

The moment I use it, the system stutters and mouse actions lag terribly

dmesg -w shows this message non-stop about 100 times a second and stops If I leave the touchpad alone  - its as if every single mouse event is causing a stall and causing this message.

Apr 02 14:30:57 archaic kernel: i2c_designware i2c_designware.1: timeout waiting for bus ready

This wasn't happening just 2 days ago - I also listed all the packages that got updated since April 1st - I can't seem to find anything that is related to this, other than the kernel
I tried rolling back the kernel from 6.8.2 to 6.7.9, to no avail

Then I changed the MatchIsTouchpad flag to "off" in /usr/share/X11/xorg.conf.d/40-libinput.conf

Section "InputClass"
Identifier "libinput touchpad catchall"
MatchIsTouchpad "off"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
EndSection

Now KDE system settings shows there is no touchpad, however, the touchpad still goes into this bad state if I just touch it after a wakeup

I would rather not have the touchpad at all - is there a way to disable it for good at the device level?

Thanks in advance

Re: [Solved] Dell Laptop touchpad going crazy after resume from hibernate

For the time being I was able to disable the touch pad by

echo 1 > /sys/devices/pci0000:00/0000:00:15.1/remove

 

from a root shell

I will mark this solved if I don't get any responses in a couple of days
