记录ubuntu下各种注意事项及常用命令
1,发热:因为硬件厂商对linux类系统的支持不足,驱动不会自动安装,所以要自己装。。。
http://www.linuxidc.com/Linux/2015-04/116450.htm
2,装上chrome后删掉firefox,su后用synaptic装 ,装软件和删软件都科研
习惯装上adblock,fireshot,getthemall三个插件

3,github上找个lantern
3,双系统切换问题:我是装的win7 + ubuntu16.04 双系统,然而可能发生ubuntu把win7的mbr干掉了
的情况,回不了win7,所以必须处理这个问题

你可以进入ubuntu 那么太好了,你只需要增加一段自动搜索的代码就可以了 代码: sudo gedit /etc/grub.d/40_custom 在文档最下面增加: 代码: menuentry '搜索并启动windows7' { recordfail gfxmode $linux_gfx_mode insmod gzio insmod part_msdos insmod ntfs search --no-floppy --file --set=root /bootmgr ntldr /bootmgr } 如果你已经知道bootmgr在第一分区(隐藏分区) 也可以这样写 代码: menuentry '启动windows7' { recordfail gfxmode $linux_gfx_mode insmod gzio insmod part_msdos insmod ntfs set root=(hd0,msdos1) ntldr /bootmgr } 最后 代码: sudo update-grub 重启选择新菜单进入
回到win7后可用easybcd修复一下
4,
软件安装命令:sudo apt-get install softname
然而很多时候“源”不对,就会说定位不到这个软件,查找不到这个软件之类的,解决方式就是换“源”,“源”这个东西就是软件中心的地址,网络上有各种各样的可提供软件下载的网络中心,
源的地址可以通过:gedit /etc/apt/sources.list 来修改
提示没有权限修改,就su到root下修改

5, 输入pwd,显示当前工作目录
6, dpkg -i soft_deb 命令可以安装deb包
7, make -j4 开启4个线程make软件,之后记得sudo make install
8, 删除软件,清理垃圾
sudo apt-get purge softwarename
sudo apt-get autoremove
sudo apt-get clean
sudo apt-get autoclean
9, 装pcl的ppa命令,然而并没什么卵用
sudo add-apt-repository ppa:v-launchpad-jochen-sprickerhof-de/pcl
sudo apt-get update
sudo apt-get install libpcl-all
10, su后 rm -rf anything
删除各种文件,可以用通配符
sudo apt-get -f install
