최근 DELL Vostro 3750 노트북에 문제가 발생하여 터치패드가 이상하게 작동합니다.
출력 을 보면 dmesg다음과 같습니다.

웹에서 찾아보니 이런 일이 일어나는 것 같네요.최신 리눅스 커널, 그러나 나는 여전히 동일한 커널을 사용하고 있습니다.

여기서 debugfs를 켜면 다음과 같이 표시됩니다.
# cat /sys/module/psmouse/parameters/proto

답변1
내 시스템을 debian/jessie 시스템으로 업데이트했는데 모든 것이 작동하지 않았습니다.
모듈을 가지고 놀고 난 후 i8k, 나는 그것이 i8kmon예정된 간격으로 실행되고 있다는 것을 깨달았습니다. 나는하기로 결정했다그만해요그리고 또한수동으로 제거모듈 i8k. 어떤 이유로 블랙리스트로는 충분하지 않았습니다.
$ cat /etc/modprobe.d/i8k-blacklist.conf

blacklist i8k
이제 터치패드가 훌륭하게 작동하며 더 이상 키보드에 문제가 없습니다. 그리고 팬도 올바른 속도로 회전하고 있습니다(이전에는 아무 이유 없이 시작/중지했습니다).
