The touchpad is not even detected in the above output. Since my machine is dual boot, the touchpad is perfectly working in Windows 10. The Touchpad manufacturer is ELAN.

In Ubuntu its not working at all.

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode.

To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/1875079/+editstatus and add the package name in the text box next to the word Package.

[This is an automated message. I apologize if it reached you inappropriately; please just reply to this message indicating so.]

[Juhani Numminen (jsonic)]

I moved thus bug under "linux" (the kernel). More information will come in an automated response.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1875079

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[You-Sheng Yang (vicamo)]

Merely marking bug as confirmed doesn't really change anything. Please still run apport to collect logs as pointed out in comment #3.

[You-Sheng Yang (vicamo)]

btw, please also attach output of `sudo acpidump -o acpidump.bin`.
