Touchpd not working properly on Linux

[Arnab Satapathi]

Installed Ubuntu 19.04 on a laptop, the touch pad is behaving abnormally.
It's detected, but nothing seems to work, however working very normal with Windows 10.

Laptop model - iBall CompBook M500

It's somewhat similar to this bug, probably using the same touchpad hardware too.

Attached some logs, with `i2c-hid.debug=1 hid.debug=1` the boot time kernel parameters added.

Thanks.

Please test this kernel:

[Arnab Satapathi (arnab1234)]

Thanks for the kernel,
unfortunately it's not working at all.
Previously the touchpad physical buttons were working with the Ubuntu default kernel.

Here's the new log with your custom kernel.

[Kai-Heng Feng (kaihengfeng)]

Somehow descriptor override doesn't work for your system.

Please test latest mainline kernel here:
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.2/

[Arnab Satapathi (arnab1234)]

The mainline kernel works fine.

Thanks for the tip.

Please could you elaborate a little what was wrong in layman's terms?

[Kai-Heng Feng (kaihengfeng)]

Please test:

It includes commit 670784fb4ebe54434e263837390e358405031d9e.

[Arnab Satapathi (arnab1234)]

It also worked just fine, no problem. Thanks you!

Can you confirm that the updated 5.0 kernel works for you?
