KDE Plasma 5: 더 이상 작업 표시줄이 없습니다(그리고 데스크탑에 마우스 오른쪽 버튼 클릭 메뉴도 없습니다)

요약:
설명된 것과 동일한 문제가 있습니다.여기. 그러나 제안된 솔루션이 나에게 적합하지 않습니다.

plasmashell나는 via 를 통해 관리 killall plasmashell하고 명령을 사용하여 수동으로 다시 시작할 수 있습니다 plasmashell.
그렇게 하면 화면에 다음 메시지가 나타납니다.

나는 그 중 대부분이 그다지 중요하지 않다고 확신하지만 다음 줄이 내 문제와 관련이 있다고 생각합니다. 빈 대화 상자를 표시하려고 합니다.

나에게 이것은 어떤 시점에서 일부 유효하지 않은 데이터가 전달/생성되어 여기에 null 값이 발생했음을 나타내며, 이것이 데스크탑이 제대로 작동하지 않는 근본 원인이라고 생각합니다.

더 긴 이야기:
그래서 저는 노트북에 Linux Mint 19를 설치하고 그 위에 KDE를 설치했습니다. 모든 것이 잘 작동합니다.
오늘 나는 내 노트북의 다른 파티션에 KDE 네온을 설치하고 (이론적으로) Mint 파티션을 완전히 변경하지 않고 그대로 두었습니다.
변경된 것은 EFI 파티션과 두 시스템이 공유하는 스왑 파티션이었습니다.
KDE Neon 설치가 Mint에서 얻은 GRUB 로더를 완전히 덮어쓴 것 같습니다(BIOS를 통해 각 시스템에 대한 로더를 선택할 수 있지만 둘 다 동일한 부트로더를 생성하므로 Neon이 Mint 로더를 덮어쓴다고 생각합니다).

하지만 정상적으로 Mint를 시작할 수는 있습니다. 유일한 문제는 로그인할 때 시작 화면이 이전보다 오래 걸리고 그 후 바탕 화면으로 이동하여 이제 시작 메뉴와 전체 작업 표시줄을 놓친다는 것입니다. 그들은 방금 떠났습니다. 바탕 화면을 마우스 오른쪽 버튼으로 클릭해도 아무 일도 일어나지 않습니다.
바탕화면에 바로가기가 모두 표시되지만 그 중 어느 하나도 클릭할 수 없습니다(보다 정확하게는 클릭할 수 있지만 아무 일도 일어나지 않습니다).

편집:
이에 대해 더 생각해 보았습니다. 설치 프로그램이 부팅 파티션을 포맷하면 설치된 커널도 제거됩니다. 따라서 문제는 KDE-Neon 커널이 Linux Mint 시스템과 완전히 호환되지 않아 몇 가지 문제가 발생할 수 있다는 것입니다. 이에 대해 좀 더 자세히 살펴보겠습니다...
