20.04의 데스크탑 환경 초기화 지연 (도움이 필요하세요!)
Aug 20 2020
명세서
디스플레이 관리자 : lightdm 1.30.0
데스크탑 환경 : gnome 3.36.3(하지만 xfce도 시도했지만)
문제 / 배경
로그인하면 (최소한 1 분 동안) 배경 화면과 마우스 만 볼 수 있습니다. 결국 나머지 데스크탑 환경이로드되고 모든 것이 잘됩니다. 로그 아웃했다가 다시 로그인하면 시작할 때와 동일한 문제가 발생하지 않습니다. 또한 tty에 로그인하는 데 시간이 오래 걸리기 때문에 tty를 사용하여 무슨 일이 일어나고 있는지 알 수 없습니다-아마도 관련 문제 (인증)일까요?
원래는 문제가 있다고 생각 lightdm했지만 gdm3월페이퍼와 마우스를 보는 대신 검은 화면이 표시되는 것을 제외하고는 동일한 문제 가 있음이 밝혀졌습니다 . 나는 이제 문제가 그놈 DE에 있다고 확신합니다.
시도
- 설치
haveged lightdm.service및startxing 비활성화- 그놈 확장 기능 비활성화 / 제거
- 설치 / 사용
gdm3 - 설치 / 사용
xubuntu-desktop - NVIDIA 독점 및 nouveau 비디오 드라이버 모두 사용
- 20.10 Groovy Gorilla로 업그레이드 (현재 시도 중-작동 / 작동하지 않는 경우 업데이트 됨)
로그 [편집 됨]
보다 구체적인 접근 방식을 취했고 15:06:20 경에 로그인 자격 증명을 입력하자마자 DE 초기화 기간 (~ 58 초)을 정했습니다. 아래의 모든 로그 journalctl는 해당 시간 프레임에서 가져온 것이며 처음 3 개는 특정 카테고리에 맞게 조정됩니다.

PAM 오류는 /etc/pam.d/lightdm에서 간접적으로 발생합니다.
#%PAM-1.0

설정 관리자-> 시스템 (섹션)-> 세션 및 시작-> 고급 (탭)- "시작할 때 KDE 서비스 시작"이 비활성화되어 있습니다.
또한 "응용 프로그램 자동 시작"에서 kwallet 또는 기타 KDE 항목을 나열 할 수 있습니다. gnome / kde 항목을 최소한으로 선택했습니다. "SSH Key Agent (GNOME Keyring : SSH Agent)"및 "GNOME 설정 재정의 마이그레이션"을 제외한 모든 gnome이 선택되지 않았으며 KDE 관련 항목이 없습니다.

비활성화 networkd-dispatcher
에서 레딧 :
네트워크 서비스 비활성화 :
시스템 관리자가 아닌 경우이 기능이 필요하지 않습니다. Gui는 어쨌든 네트워크 관리자를 사용합니다 (그리고 자체 디스패처가 있습니다).
sudo apt-get remove networkd-dispatcher
sudo systemctl stop systemd-networkd.service
sudo systemctl disable systemd-networkd.service
다른 부팅 속도 팁이 있지만 이것은 귀하의 경우와 가장 관련이 있습니다.
버그 신고
문제에 대한 버그 보고서가 있습니다.
- pam_unix (sudo : auth) : / etc / securetty를 열 수 없음 : 해당 파일 또는 디렉토리가 없습니다.
16.04 에는 문제가없는 것 같기 때문에 20.04 로 시작된 것 같습니다.
$ ll /etc/securetty
-rw-r--r-- 1 root root 4038 Mar 29 2016 /etc/securetty
버그 보고서를 구독하고 진행 상황을 따라야합니다.
