ThinkPad X1 Carbon Gen7: trackpad randomly stops responding for some time

Open sreehax opened this issue 5 years ago • 2 comments

I followed the installation instructions on the README and when I kldloaded iichid my trackpad did work though not consistently. Sometimes the trackpad just stops responding to movement. Sometimes it's fixed by waiting or clicking around. Otherwise I basically have to use the trackpoint. Are there any files/info I can provide to help debug this issue? I'm running on a 12.2-STABLE compiled a few days ago.

Please provide:

  1. Console output of kldloading iichid.ko on debug level 1 (default for wulf7/iichid, sysutils/iichid enables it with DEBUG option turned on at port compile stage).
  2. Install devel/evemu, run evemu-record as root in terminal window and choose your touchpad as source. It will show touchpad events when they are coming out of kernel through /dev/input/event* character device. Do they stop while touchpad freezes?
