사실, 이다 하지만 대신에 몇 가지 해킹과, 지연없이 그것을 할 수 있습니다. 나는 당신이 지체없이 그것을 할 수있는 작은 스크립트를 작성했습니다. 이것은 큰 해킹이지만 작동하고 지연을 사용하는 것보다 확실히 나에게 더 좋습니다.

실제로 우분투에서 스크립트를 사용하기 전에 xinput 과 unbuffer 가 있는지 확인해야합니다 . 그렇게하려면 다음을 수행하십시오.

sudo apt-get install xinput expect-dev

그런 다음 스크립트를 실행할 수 있습니다. 가능한 구성 옵션을 보려면 -h 옵션으로 먼저 실행하십시오. 기본적으로 스크립트는 한 번만 작동하며 모든 스크린 샷 (예 : 키보드 단축키) 후에 스크립트를 다시 시작해야합니다. 스크립트가 성능에 영향을 줄 수 있기 때문입니다. “데몬”으로 실행하려면 -d옵션을 사용하여 실행하십시오 .

기본적으로 셔터도 사용됩니다. 다른 것을 사용하려면 -e옵션을 사용하십시오 . 예 :script.sh -c "ksnapshot"

기본적으로 캡처 버튼은 Meta+ R입니다. 구성 옵션을 사용하여 변경할 수 있습니다.
