내 시스템이 매우 느려졌습니다. 부팅하는데 15초가 걸렸습니다. 이제 부팅하는데 3분 이상이 걸립니다. 저는 듀얼 부팅(Ubuntu 및 Windows)을 사용하는 Dell을 사용하고 있으며 스왑 디스크 할당 및 기타 Nvidia 관련 문제에 대해 읽었습니다. 부팅 속도를 향상시키는 것은 아무것도 없는 것 같습니다.
systemd-analyze time
시작 시간은 5.680초(펌웨어) + 3.578초(로더) + 33.469초(커널) + 3분 475ms(사용자 공간) = 3분 43.204초입니다. 그래픽 목표는 사용자 공간에서 1분 36.087초 후에 도달했습니다.

스왑 파티션이 있는지 확인하고, 있다면 /etc/fstab에 설정된 해당 UUID가 올바른지 확인하십시오.
