커널 5.1.0-6.4-liquorix-amd64 #1 ZEN SMP PREEMPT liquidix 5.1-4ubuntu1~bionic (2019-06-03) x86_64 x86_64 x86_64 GNU/Linux가 포함된 LUbuntu 18.04가 포함된 Dell Venue 변환기가 있습니다. PBTN을 제외한 모든 장치의 깨우기를 비활성화했습니다. BIOS에서 USB PowerShare가 꺼져 있습니다.
그럼에도 불구하고, 일시 중지 후에도 노트북은 따뜻한 상태를 유지합니다. 세 가지 장치만 전원 상태를 변경하지 않습니다.

제어되지 않는 USB LED 장난감으로 테스트한 결과 일시 중지 중에도 켜져 있는 것으로 나타났습니다. laptop-mode-tools를 설치하는 것은 도움이 되지 않습니다(일부 추가 설정이 필요할 수도 있음).
장치를 S3 또는 S4 상태로 설정하는 방법은 무엇입니까?

최근에 USB로 인해 갑자기 일시 중지가 작동을 멈췄을 때 비슷한 문제가 발생했습니다. 이 문제를 해결하기 위해 다음 스크립트를 작성했습니다.

done
rm $TMPLIST

스크립트를 배치 /lib/systemd/system-sleep/custom-xhci_hcd하고 다음을 사용하여 실행 가능으로 표시합니다.
chmod a+x /lib/systemd/system-sleep/custom-xhci_hcd
다음 재부팅 시 스크립트가 활성화됩니다.
