Debian10->11로 업그레이드한 후 KDE 플라즈마를 시작할 수 없습니다(검은색 화면).

데비안 10에서 11로 업그레이드했습니다. 업그레이드를 완료하고 디스크 공간 부족(공간이 충분해야 함), 일부 rkhunter 구성 및 konsole 명령을 차단하는 무인 업그레이드로 인해 문제가 발생한 후 재부팅했습니다.

첫 번째 이상한 점은 grub 비밀번호를 묻는 초기 부팅 화면이 빨간색이라는 점입니다. 파란색이 아닌 조금 이상해 보이지만 빠르게 다시 파란색으로 변경됩니다. 두 번째 문제는 로그인한 후에 검은 화면만 나타난다는 것입니다(상단에 일부 창이 있음). 이는 Plasshell이 ​​실행되고 있지 않기 때문입니다(실행 중인 유일한 것은 입니다 startplasma-x11). 그래서 kstart5 plasmashell. 그러나 완전히 로드된 직후(데스크톱 및 작업 표시줄 표시) 충돌이 발생하는 것 같습니다. 이 문제를 해결하는 방법? 전체 출력은 다음과 같습니다.

Omitting both --window and --windowclass arguments is not recommended
