touchpad not detected

[hussam]

I'm unable to get the name of the touchpad on system. And, I'm unable to copy text as well to support investigation on this bug-report. The following bug-report was the closest to my issue. However, I tried to use the patched kernel (mainline 4.17.0-1-generic) but it didn't fix my problem.
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1728244

I tried updating the GRUB_CMDLINE_LINUX_DEFAULT wit i8042.reset and i8042.nomux, but it didn't work as well.

I'm using Ubuntu 18.08 LTS on a tablet PC that came preloaded with windows 10. The device is called Cherry ZE55L, it's very close to Chuwi products.

[Joseph Salisbury (jsalisbury)]

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report[0]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

Please follow the instructions on the wiki page[0]. The first step is to email the appropriate mailing list. If no response is received, then a bug may be opened on bugzilla.kernel.org.

Once this bug is reported upstream, please add the tag: 'kernel-bug-reported-upstream'.
