thinkpad t440p Linux trackpad + trackpoint not working.

#1 Post by jaggreaney » Thu Nov 09, 2023 2:54 pm

My ThinkPad T440p is running Linux Mint however, there's an issue where the Track Point and touch pad work inconsistently after startup. They function for only a brief period, even though Linux Mint recognizes the devices. This problem occurs intermittently and lasts only a few seconds. This happened because I've swapped out the track pad with one from a T450, I replaced the track pad cable, and I also replaced the keyboard as well. Keyboard works fine track point does not. Have any of you guys experienced this problem what could be the done to fix this issue?

There are 2 versions of the T450 touchpad, see https://forum.thinkpads.com/viewtopic.php?f=68&t=126860
Maybe you use the wrong driver?
