Hello, I first tried to install the kernak using the instructions as you provided, but it complained about missing libssl** package, which I installed, leading to another complain of missing ' linux-headers-4.19.0' package. After bit of googling to find this package, I ended up to install the latest 4.19 Kernal following the instructions of this page [1], here is the information of my latest kernal [2] and here is the output of trying to install the 4.19**generaic*.deb package, the Kernal remains same as before [2]. Anyways, I did reboot the system and it unfortunately did not change anything. The mouse behavior is still the same as before. Here is the output of [3] xinpout --list-props 12 [1] http://www.theubuntumaniac.com/2018/09/install-update-linux-kernel-419-rc3-on.html [2] *************************** pooja@X1-Carbon-6:~/Desktop$ uname -r 4.19.0-041900rc3-lowlatency pooja@X1-Carbon-6:~/Desktop$ uname -a [2] *************************** pooja@X1-Carbon-6:~/Desktop$ sudo dpkg -i linux-modules-4.19.0-041900rc3-generic_4.19.0-041900rc3.201809120832_amd64.deb (Reading database ... 281748 files and directories currently installed.)
