xterm은 설정이 되고

리부팅 이후에는 lxterm도 적용은 되나.. 클릭이나 드래그로는 안되서

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

gnome으로 찾으니 안나오지 ㅠㅠ

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..

$ pkg-config opencv --libs

$ sudo find / -name "*.pc" | grep opencv

/home/pi/src/openCV/opencv-3.0.0/build/unix-install/opencv.pc

/usr/lib/pkgconfig/opencv.pc

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

$ sudo mv /usr/local/lib/pkgconfig/opencv.pc /usr/local/lib/pkgconfig/opencv.pc.bak

$ sudo ldconfig

$ pkg-config opencv --libs

정보는 바뀌는데 정작 빌드 하면 이상하게 된다.. ㅠㅠ

그냥 부하가 걸리는건줄 알았는데 아니구나...

Default mode

Blue: low priority processes (nice > 0)

Green: normal (user) processes

Red: kernel time (kernel, iowait, irqs...)

Orange: virt time (steal time + guest time)

Detailed mode

Blue: low priority threads (nice > 0)

Green: normal (user) processes

Red: system processes

Orange: IRQ time

Magenta: Soft IRQ time

Grey: IO Wait time

Cyan: Steal time

Memory meters are more straightforward:

Green: Used memory pages

라즈베리에 까는데

용량들이 왜케 후덜덜 한거야...

f-spot은 사진 관리용이지.. 스샷은 안되고

shutter는 깔기만 했는데 용량이 ㅎㄷㄷ하게 깔려서 패스

gimp는 캡쳐하나 하자고 포토샾 까는 꼴이고..

그나마 무난하고 만만한건 gnome-screenshot(용량적고 강추)

sysfs나 캐릭터 디바이스로 하드웨어와 통신을 하기 위한 인터페이스(?)라고 하면 되나..

아무튼 온도 센서 등과 같은 gpio를 이용하는 비표준 통신 장비들과(그래서 I2C 이런것과 달리 Industrial이라고 한 듯)

통신을 할 수 있도록 해주는 것으로 보이는 sub-system 이다.
