The latest Ubuntu 15.04 has been released. I have been longing for Linux for a long time and finally I can't help but install Ubuntu.
The new Ubuntu brings a new kernel, new software and a new experience.
The kernel version of Ubuntu15.04 is 3.19. The new kernel means that more and newer hardware will be supported, more full use of hardware functions, better stability and fewer bugs.
Although the latest version of Ubuntu has many very good features, there are still many places that need to be optimized by ourselves.
1. Set full screen
In the Settings Center Appearance item, set Hide left launcher. This will enable full screen when Google Chrome or other software is enabled.
2. Remove libreoffice
Although the new version of LibreOffice is open source, very beautiful, and has a good compatibility with Microsoft's office software, the execution efficiency of office written in Java is really not flattering, so I decided to delete it.
sudo apt-get remove libreoffice-common
3. Install WPS
At present, Microsoft has not released the Linux version of Office, and can only make do with WPS.
sudo apt-get install wps-office
4. Remove the link to Amazon
sudo apt-get remove unity-webapps-common5. Delete the software that is basically not used in the system
sudo apt-get remove thunderbird totem rhythmbox empathy brasero simple-scan gnome-mahjongg aisleriot gnome-mines cheese transmission-common gnome-orca webbrowser-app gnome-sudoku landscape-client-ui-install
sudo apt-get remove onboard deja-dupThis way the system will be much cleaner.
6. Install Google Chrome
Although the built-in Firefox browser is also good, but still can not leave the beloved Google browser.
Go to https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb to download the latest installation file. Then:
sudo apt-get install libappindicator1 libindicator7 sudo dpkg -i google-chrome-stable_current_amd64.deb sudo apt-get -f installThis will allow you to apt install and update Google Chrome in the future.
7. Install vim
There is no integrated Vim artifact by default, and it can only be installed manually.
sudo apt-get install vim8. Install Oracle Java
The system comes with OpenJDK, but it is the Java7 version. As programmers pursuing new technologies, we should bravely move towards Java8, so we need to install Oracle Java.
sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java8-installerAfter uninstalling OpenJDK, there will be residues, causing the operation
java -versionWhen the first line is not the java version number, it will be Picked up JAVA_TOOL_OPTIONS: -javaagent:/usr/share/java/jayatanaag.jar This prompt will cause many scripts to detect the java version number to run incorrectly, so you need to manually clear the residue.
sudo rm /usr/share/upstart/sessions/jayatana.conf删除/usr/share/upstart/sessions/jayatana.conf文件，重启之后再运行java-version就不会再有 Picked up JAVA_TOOL_OPTIONS: -javaagent:/usr/share/java/jayatanaag.jar提示了。
9.自定义DHCP网络的DNS Server IP地址
因为DNS的缘故，系统的网速并不怎么给力。
所以我们使用下面这行命令
sudo vim /etc/dhcp/dhclient.conf打开dhclient.conf这个文件。在第21行#prepend domain-name-servers 127.0.0.1;下一行添加如下3行使用aliyun和Google的DNS。
prepend domain-name-servers 8.8.8.8; prepend domain-name-servers 223.5.5.5;这样可以优先使用aliyun的dns，次要使用Google的DNS。
10.安装git和vpnc
git和vpn大家都懂的，程序员的好工具。
sudo apt-get install vpnc git11.安装axel
axel是Linux命令行界面的多线程下载工具，比wget的好处就是可以指定多个线程同时在命令行终端里下载文件。安装之后，就可以代替wget用多线程下载了。
sudo apt-get install axel12. 安装bcloud
百度网盘的官方客户端有 Windows 版和 Mac 版，但就是没有 Linux 版，不过使用 Linux 的童鞋可都是有两下子的嘛，于是一个第三方百度网盘客户端就出现了，这就是 bcloud。
曾开发 Linux 下的酷我播放器 KWplayer 的作者 Liulang，写了一款百度云 Linux 客户端–Bcloud。
bcloud 的使用方法跟其他版本的客户端大致上是一致的，拖拽文件就可以完成上传下载操作，而且还整合了离线下载功能，使用起来更方便了。
同时 bcloud 还有流媒体模式，支持调用本地媒体播放器去播放网盘里的媒体，而不是使用 Flash，性能上更强大。不过遗憾的是目前 bcloud 还不支持同步功能。
按照上面的地址下载所需的包：https://github.com/LiuLang/bcloud-packages
安装就可以了。
有人问我，为什么不安装个搜狗输入法？因为在Ubuntu 15.04 里，Fcitx中文输入法代替 IBUS 成为默认输入法，已经能够承担起输入法的重任，不输于搜狗输入法了。
做完这些，你就可以好好享受你的Ubuntu15.04了。
