내 기능 키 중 일부를 수정하는 동안, BIOS를 업데이트하기로 결정했습니다. 이 방법으로 원래 문제가 해결되지는 않았지만 터치패드가 더 이상 작동하지 않습니다!
처음에는 첫 번째 재부팅 후에도 여전히 들어 /proc/bus/input/devices오고 나가는 것으로 나타났지만 xinput작동하지 않는 것 같았습니다. 그런 다음 Ubuntu(19.10)에서는 많은 새 업데이트를 설치하라는 메시지를 표시합니다.
첫째, 더 이상 GRUB2에서 우분투로 부팅할 수 없었습니다(Windows에서 이중 부팅을 실행 중이었습니다). 이 문제는 커널을 vmlinuz-5.3.0-19-generic항목에 있는 커널로 변경하여 빠르게 해결되었습니다(4.xx-23에서라고 생각합니다).
그러다가 마침내 성공적으로 재부팅한 후 터치패드가 더 이상 나타나지 않거나 /proc/bus/input/devices전혀 xinput나타나지 않습니다! 내가 찾은 유일한 추적은 다음 출력입니다 dmesg.

이 문제를 해결하는 방법을 아는 사람이 있나요?
편집하다:
뒤쪽에LinuxSecurityFreak의 제안다음을 사용하여 터치패드를 활성화하려고 합니다.
sudo rmmod elan_i2c
sudo modprobe elan_i2c
/proc/bus/input/devices그 후 와 에서 다시 터치패드가 등장했습니다 xinput! 하지만... 여전히 작동하지 않습니다.
/var/log/syslog다음을 신고하세요 sudo rmmod elan_i2c.

이상하게도 동일한 명령을 다시 실행하면 터치패드가 다시 사라지고 sudo modprobe elan_i2c다른 출력이 표시됩니다.

답변1
AskUbuntu에 대한 이 질문똑같은 오류인 것 같고 해당 답변으로 내 문제가 해결되었습니다. 간단히 말해서:
- 시작 후 실행하여
sudo sh -c 'echo -n "elantech"> /sys/bus/serio/devices/serio1/protocol'터치패드가 제대로 작동하도록 하거나 psmouse.elantech_smbus=0시작 시 문제를 해결하기 위해 시작 옵션에 추가되었습니다 .
