Sam, agreed. I'm not sure expecting the touchpad to be detected when ACPI is disabled is a reasonable technical expectation (although having a working touchpad is a reasonable expectation).
Hence, this report should refocus to why you have to disable ACPI in the first place (which in itself is a very drastic move). With this in mind, as per https://www.msi.com/Laptop/support/GP72-6QE- Leopard-Pro.html#down-bios an update to your computer's buggy, insecure, and outdated BIOS is available (E1795IMS.114). When you update to this following https://help.ubuntu.com/community/BIOSUpdate does this improve your situation? For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. Also, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid. Thank you for your understanding. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1584479 Title: [MSI GP72 6QE Leopard Pro] Touchpad not detected on 16.04 Status in linux package in Ubuntu: Incomplete Bug description: Hi, I just install Ubuntu 16.04 on my new MSI laptop G72 6QE.
