sudo -s tar xvzf jre-7u21-linux-x64.tar.gz

3. 환경변수 설정.

sudo vi /etc/profile

JAVA_HOME=/usr/local/java/jdk1.7.0_21

PATH=$PATH:$HOME/bin:$JAVA_HOME/bin

JRE_HOME=/usr/local/java/jre1.7.0_21

PATH=$PATH:$HOME/bin:$JRE_HOME/bin

export JAVA_HOME

export JRE_HOME

export PATH

를 추가하고 저장.

4. 우분투 패키지 관리자에 자바 바이너리 설정시키기.

sudo update-alternatives --install "/usr/bin/java" "java" "/usr/local/java/jre1.7.0_21/bin/java" 1

sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/local/java/jdk1.7.0_21/bin/javac" 1

sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/local/java/jre1.7.0_21/bin/javaws" 1

5. 우분투 패키지 관리자에 default로 인식되게 설정하기

sudo update-alternatives --set java /usr/local/java/jre1.7.0_21/bin/java

sudo update-alternatives --set javac /usr/local/java/jdk1.7.0_21/bin/javac

sudo update-alternatives --set javaws /usr/local/java/jre1.7.0_21/bin/javaws

6. 재부팅 후, 설치 확인

sudo shutdown -r now

java -version

출처  : http://www.wikihow.com/Upgrade-Oracle-Java-on-Ubuntu-Linux

exfat 설치

sudo add-apt-repository ppa:relan/exfat

sudo apt-get update

sudo apt-get install fuse-exfat

파티션 확인

sudo fdisk -l

exfat로 mount

sudo mount.exfat-fuse /dev/sdb3 /windows -o umask=0

mount 정보 보기

mount

uuid 알아내기

sudo blkid

/etc/fstab 설정.

UUID=9048-40C8                            /windows        exfat   rw,nosuid,nodev 0 0

1. 방법1 ppa를 통한 설치

sudo jockey-gtk 

에서 현재 설치된 모든 그래픽 드라이버 제거.

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates  

로 ppa추가

sudo apt-get update

sudo apt-get install nvidia-current

2. 방법2 홈페이지에서 다운로드 (비추)

http://www.nvidia.co.kr/Download/index.aspx?lang=kr

에서 드라이버 설치파일 다운로드

sudo vi /etc/modprobe.d/blacklist.conf

##### 추가 #####

blacklist vga16fb

blacklist nouveau

blacklist rivafb

blacklist nvidiafb

blacklist rivatv

##############

sudo apt-get --purge remove nvidia-*

sudo shutdown -r now

로그인시, grub 부트로더에서

nomodeset=0 3 text

옵션 추가

드라이버 설치파일이 있는 디렉토리로 이동

chmod 755 ./NVIDIA*

sudo sh ./NVIDIA*

sudo apt-get install xinit

1. 기존 wine 제거

sudo apt-get autoremove wine --purge

sudo apt-add-repository ppa:ubuntu-x-swat/x-updates

sudo apt-get update

sudo apt-get install nvidia-cur

5-2 NVIDIA 공식 드라이버 사용. < 5-1 로 안되면 >

http://lockpick.tistory.com/entry/nvidia-드라이버-설치

5-3 nvidia 제거. (nouveau 사용)  < 5-2 로 해결 안되면 >

5-3-a 공식 NVIDIA 제거.

# ./NVIDIA-*.run --extract-only
# cd NVIDIA-*
# nvidia-installer --uninstall
# shutdown -r now

5-3-b nvidia-current 제거.

sudo apt-get --purge remove nvidia-current

6.  LoadLibraryShim error reading registry key for installroot

don't worry about it.

1. fstab 설정  (trim, tmp 설정)

sudo vi /etc/fstab

UUID=장치번호 /   ext4   noatime,nodiratime,discard,errors=remount-ro 0 1

.... 중간 생략 ...

tmpfs   /tmp       tmpfs   defaults,noatime,mode=1777   0  0

tmpfs   /var/spool tmpfs   defaults,noatime,mode=1777   0  0

tmpfs   /var/tmp   tmpfs   defaults,noatime,mode=1777   0  0

2. /etc/default/grub 설정  (scheduler 설정)

sudo vi /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash elevator=deadline"
 
sudo update-grub2

재부팅

확인방법) cat /sys/block/{DEVICE-NAME}/queue/scheduler

예 : cat /sys/block/sda/queue/scheduler

noop [deadline] cfq

위처럼 나오면 성공.

3. /etc/sysctl.conf 설정 (swappiness 설정)

sudo vi /etc/sysctl.conf

vm.swappiness=0

vm.vfs_cache_pressure=50

위와 같이 나올시 성공.

5. chromium 설정 (설치 했다면)

sudo vi /etc/chromium-browser/default

CHROMIUM_FLAGS="--disk-cache-dir=/tmp"

1. 패키지 설치.

sudo apt-get install fbterm uim uim-byeoru uim-fep ttf-nanum-coding ttf-dejavu

2. uim 설정

$ uim-pref-qt4
