03 刚安装了Fedora，进去就是Gnome环境的，想切换到KDE，怎么弄

Posted 2023-04-02

如果会用linux，可以参考官方安装手册
http://fedoraproject.org/wiki/KDE
建议在kde稳定运行后才卸载gnome。
我就搞乱顺序坑过自己一次。 参考技术A 装kde版本
然后在登录时选择kde

fedora24安装后,配置环境

1.设置终端打开的快捷方式

右键->settings->keyboard->Custom Shortcuts->...

2.添加fedora中文社区源

wget wget http://repo.fdzh.org/FZUG/FZUG.repo -P /etc/yum.repos.d/

3.禁止输入时鼠标光标闪烁

gsettings set org.gnome.desktop.interface cursor-blink false
4.配置vim

安装一些插件:ctrp delimiMate tagbar vim-pathogen vim-surround YouCompleteMe
编译YCM

    1)mkdir ~/ycm_build&&cd ~/ycm_build

    2)安装vim(>7.4版本,也要支持python),cmake,clang(会用到里面的libclang.so,版本>=3.8)

    cmake -G "Unix Makefiles"  ~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp
    -DEXTERNAL_LIBCLANG_PATH=/usr/lib64/libclang.so.3.8

    此时,在  /home/lw/.vim/bundle/YouCompleteMe/third_party/ycmd里面有两个.so文件

    即libclang.so.3.8和ycm_core.so,编译就完了.

    3)cp .vim/bundle/YouCompleteMe/third_party/ycmd/examples/.ycm_extra_conf.py ~/

    根据自己情况修改里面的配置就行了.

 
5.修改/etc/bashrc

export EDITOR=/usr/bin/vim

export network=/etc/sysconfig/network-scripts

alias vi=‘vim‘
