시작 시 밑줄이 깜박이면서 화면이 깜박입니다.

그 후 aptitude safe-upgrade내 노트북이 부팅을 멈췄습니다.

녹음했어요이 비디오시작 프로세스.

tty1에 액세스할 수 있고 거기에서 startx문제 없이 실행할 수 있습니다. 출력은 다음과 같습니다.

Mate는 Lightdm을 사용하므로 제거하고 다시 설치했지만 아무런 차이가 없었습니다. 그런 다음 lxdm을 사용하는 XLDE를 설치했습니다. 동일한 문제가 다시 발생합니다. 화면 깜박임 및 커서 깜박임.

x를 수동으로 시작할 수 있기 때문에 이것은 X와 관련이 없으며 Mate와 LXDE 모두에서 동일한 문제가 있기 때문에 데스크탑 환경과 관련이 없습니다.

이 문제를 해결하기 시작해야 할 제안 사항이 있는 사람이 있습니까?
