Before we were able find the cause of our trackpad issue we tried a number of different things. I noticed that the 4.19 mainline kernel seemed to work fine even with i2c_i801 loaded. Maybe this is actually a kernel bug?
I opened the bug report here because it seemed like a regression to ubuntu stable for our hardware. The trackpad worked prior to installing the updated kmod package. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to kmod in Ubuntu. https://bugs.launchpad.net/bugs/1802135 Title: broken touchpad after i2c-i801 blacklist change Status in kmod package in Ubuntu: New Bug description: After upgrading to kmod (24-1ubuntu3.1) the trackpads stop working on Lenovo 11e 2nd gen machines.
