xterm은 설정이 되고

리부팅 이후에는 lxterm도 적용은 되나.. 클릭이나 드래그로는 안되서

우클릭을 해야 이전 페이지로 갈수 있다는건... 설정을 잘못한걸려나?

네트워크 아이피 설정하려고 쑈하는데

어떤 프로그램인지 몰라서 한참 헤메다가 이제야 생각났네..

$ nm-connection-editor

음.. 우분투 x86 머신을

synology 처럼 네트워크 접속시 자동으로 깨어나도록 하고 싶어서

찾아 봤더니 키워드를 잘못 찾아서 헤메고 있었던 기분...

아무튼.. 범용제품으로는 ARM cpu를 채용한 녀석만큼

딱 입맛에 맞춰서 재웠다 깨웠다는 조금 힘들려나..

매번 WOL로 살리는것도 귀찮은데..

opencv 3.0.0을 빌드해서 올렸다.. 다시 돌릴려는데 영 안되네..

/usr/local/lib/pkgconfig/opencv.pc

정보는 바뀌는데 정작 빌드 하면 이상하게 된다.. ㅠㅠ

그냥 부하가 걸리는건줄 알았는데 아니구나...
