After some time the Touchpad now stops working and is not usable. External Mouse works fine.

modprobe -r elan_i2c
modprobe elan_i2c

is a workaround. But Touchpad still freezes after some time.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.19 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Thanks for your reply.
This is a new laptop, so I am not able to say anything about prior kernel versions.
With upstream kernel v4.19 the issue persists.

Both elan_i2c and hid_i2c want to use the device. Can you blacklist either one of these to see which one really works?

Philipp (philipp30) wrote on 2018-10-03:

modprobe -r elan_i2c disables the touchpad.
modprobe -r i2c_hid doesn't seem to have any effect.

echo "blacklist i2c_hid" | sudo tee -a /etc/modprobe.d/blacklist.conf
doesn't seem to have any effect either.

Philipp (philipp30) wrote on 2018-10-03:

Also did
depmod -a
update-initramfs -u

and verified with
lsmod | grep i2c
that i2c_hid is not loaded.

still elan_i2c kernel errors in syslog.

I did post the issue to the mailing list but did not receive any answer for the past 14 days. I know that other users are affected too, for example at reddit. This is really bad, because it essentially means that this laptop can not be used with linux at all without external mouse.

This error happens, but even when I am not touching anything, I do ctrl alt f5 and it spams the shell. I can’t even put a command in. The only things I can do are shut down and exit shell.

Also, my syslog file took up 1.1 Gb. My computer only has 16. (Chromebook, soooo...) Even if I delete it, it comes back.

Doing
sudo rmmod i2c_hid
sudo rmmod hid
worked for me.

Please test the kernel in -proposed. It should solve this issue.

Would 5.0.0-rc* work?

No, it's not in 5.0-rc* yet.

Does anyone know which kernel DOES have this fix so I can upgrade ? This is an annoyance.

Similar problems with Acer TravelMate B118-M that has ElanTech touchpad ELAN0502.
My distro is Lubuntu 16.04.6 LTS 64 bit with 4.15.0-60-generic kernel (up-to-date).
Tried to upgrade the kernel to latest releases, but it claims for libssl1.1 (used in 18.04) and 16.04 uses libssl1.0
I tested the laptop with Lubuntu 18.04.3 64bit (USB installation stick) that it comes with 5.0.0-23-generic kernel and it works!
