Hello, Thanks for your reply. I remember that I did play around with kernal change as my first attempt to fix the touchpad issue, but can not confirm changing to other Kernal intentionally. And the problems with 18.04 persist since day-1.
The steps I followed for testing the latest Kernal: 1. uninstall Oracle Virtual Box 2. Download linux-headers-4.19.0-041900rc2-generic_4.19.0-041900rc2.201809022230_amd64.deb from [0] 3. Got error while installing the latest kernal [1] 4. While google around for how to fix the issue, found this page [2], the installation failed as well giving series of error messages [3] If there is a way to fix these problems, I would be really keen to try them. But as you know, that this is affecting my work, so I might wanna try lower version, I did a test with USB installed 16.04, everything worked with that. In my understanding, if I installed that, then also it would keep working fine?
