Ubuntu16.04安裝之後2

1.gedit亂碼

終端：

gsettings set org.gnome.gedit.preferences.encodings candidate-encodings "['GB18030', 'UTF-8', 'CURRENT', 'ISO-8859-15', 'UTF-16']"

參考：http://blog.csdn.net/kang99827765/article/details/51426855

2. zip解壓亂碼

unzip -O GBK xxx.zip

如:unzip -O cp936 2018畢業設計文檔模板.zip  ----這個是大寫的O

參考:https://www.zhihu.com/question/20523036

在windows下壓縮的zip是GBK編碼 在linux是utf-8。（並不是所有的unzip解壓都會亂碼）

3.install git

sudo apt-get install git

配置郵箱和用戶名

git config --global user.name "Your Name"
git config --global user.email "[email protected]"

4.刪除亞馬遜鏈接及libreoffice

sudo apt-get remove unity-webapps-common

sudo apt-get remove libreoffice-common

5.刪除不常用軟件

sudo apt-get remove thunderbird totem rhythmbox empathy brasero simple-scan gnome-mahjongg aisleriot 
sudo apt-get remove gnome-mines cheese transmission-common gnome-orca webbrowser-app gnome-sudoku  landscape-client-ui-install   
sudo apt-get remove onboard deja-dup

6.更新補丁

sudo apt-get update
sudo apt-get upgrade

參考：http://blog.csdn.net/MasterAnt_D/article/details/56839492

7.install jdk

法1.可以從官網下載tar 安裝

法2.命令行安裝

sudo add-apt-repository ppa:webupd8team/java
sudo apt update
sudo apt install oracle-java8-installer

Set Java environment variables and Oracle JDK8 as default

sudo apt install oracle-java8-set-default

若出現這個問題：

Oracle JDK 8 is NOT installed.
dpkg: error processing package oracle-java8-installer (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 oracle-java8-installer
E: Sub-process /usr/bin/dpkg returned an error code (1)**

參考：https://askubuntu.com/questions/966107/cant-install-oracle-java-8-in-ubuntu-16-04/996986#996986

終端執行：

cd /var/lib/dpkg/info
sudo sed -i 's|SHA256SUM_TGZ="2ef49c97ddcd5e0de20226eea4cca7b0d7de63ddec80eff8291513f6474ca0dc"|SHA256SUM_TGZ="1c6d783a54fcc0673ed1f8c5e8650b1d8977ca3e856a03fba0090198e0f16f6d"|' oracle-java9-installer.*
sudo sed -i 's|JAVA_VERSION_MINOR=181|JAVA_VERSION_MINOR=181|' oracle-java9-installer.*
sudo sed -i 's|FILENAME=jdk-${JAVA_VERSION_MAJOR}+${JAVA_VERSION_MINOR}_linux-${dld}_bin.tar.gz|FILENAME=jdk-${JAVA_VERSION_MAJOR}_linux-${dld}_bin.tar.gz|' oracle-java9-installer.*
sudo sed -i 's|PARTNER_URL=http://download.java.net/java/jdk${JAVA_VERSION_MAJOR}/archive/${JAVA_VERSION_MINOR}/binaries/$FILENAME|PARTNER_URL=http://download.oracle.com/otn-pub/java/jdk/${JAVA_VERSION_MAJOR}+${JAVA_VERSION_MINOR}/$FILENAME|' oracle-java9-installer.*

sudo apt-get install oracle-java8-installer

測試：java -version 和javac -version

找到java的安裝路徑：sudo update-alternatives --config java

可知安裝路徑爲：/usr/lib/jvm/java-8-oracle

配置環境變量：（這個環境變量可以在很多地方設置 如/etc/environment 或者/etc/profile 區別可以自行google ）

sudo gedit /etc/environment
添加如下一行：JAVA_HOME="/usr/lib/jvm/java-8-oracle"

如果用/etc/profile 參考這個：

JAVA_HOME=/usr/java/jdk1.7.0_40
CLASSPATH=.:$JAVA_HOME/lib.tools.jar
PATH=$JAVA_HOME/bin:$PATH
export JAVA_HOME CLASSPATH PATH

重讀環境文件:

source /etc/environment

命令：echo $JAVA_HOME
返回：/usr/lib/jvm/java-8-oracle

重啓即可

安裝eclipse之後  如果彈出 /usr/lib/jvm/java  crashed. 看一下你的eclipse裏的錯誤日誌文件.

日誌文件像這樣:

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0x00007f3fbd7a8c4c, pid=28399, tid=0x00007f4050387700
#

#
# Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again
#
# If you would like to submit a bug report, please visit:
#   http://bugreport.java.com/bugreport/crash.jsp
#

原因:你的eclipse後臺要求是gtk2, 而你的eclipse用的是gtk3. 所以在eclipse.ini裏,在  --launcher.appendVmargs 之前添上

--launcher.GTK_version

8.截圖

sudo apt-get install shutter

這個既可以截圖也可以編輯

快捷鍵 shift + prtsc 也可以截圖但是不能編輯

9.攝像頭開啓

快鍵鍵:
