우분투를 다시 사용하는 데 뛰어 들었지만 우분투 19.04의 전반적인 성능에 실제로 문제가 있습니다. 매우 느리고, 잠기지 만 최악의 경우 부팅하는데 약 5 분이 소요될 수 있습니다.
8GB RAM이 장착 된 i3 3000 프로세서와 Intel HD 3000 온보드 그래픽을 사용하는 구형 Dell Optiplex 7010이 있습니다. 따라서 성능은 그렇게 문제가되지 않아야합니다.
내가 언급했듯이 나는 여전히 우분투를 처음 접하므로 여전히 배우고 있습니다.
수정 프로그램을 검색 한 후이 명령을 사용하여 Ubuntu를 부팅하는 데 많은 시간이 걸리는 것을 확인했습니다.

보시다시피 뭔가 옳지 않습니다. 누군가이 문제를 해결하도록 도와 줄 수 있다면 고맙겠습니다.
우분투 19.04는 비교적 새로운 설치입니다. 그러나 새로 설치하면 성능 문제가 있다고 말할 수 있습니다. 누군가 가이 문제를 해결하도록 도울 수 있기를 바랍니다. 그렇게하는 법을 배우기를 고대하고 있습니다.

수많은 스냅 앱이 설치되어 있습니다. 각각은 성능이 저하됩니다. 각 스냅을 제거하고 표준 앱으로 교체하십시오.

느린 성능 및 특히 잠금은 고장난 하드 드라이브의 증상 일 수 있습니다. 드라이브 펌웨어가 고장난 섹터를 여러 번 다시 읽으려고 할 수 있습니다. 하드 드라이브의 SMART 상태를 확인하는 것이 좋습니다.

@starkus Plymouth는 동시에 실행됩니다. 다른 부팅 프로세스가 더 빨리 완료되면 더 빨리 완료됩니다. , 읽어 보시기 바랍니다 : askubuntu.com/a/1168249/968501
