  • ubuntu desktop使用中遇到的问题

    ubuntu无法读取windows下的硬盘

    出错信息

    Error mounting /dev/sda6 at /media/jcuan/media: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sda6" "/media/jcuan/media"' exited with non-zero exit status 14: The disk contains an unclean file system (0, 0).
    Metadata kept in Windows cache, refused to mount.

    原因

    windows8之后启用的fast startup

    In normal shut down process, power is removed from all components such as CPU, RAM, CD-Rom and hard disks. But in fast start up, Windows 8 saves some system information such as caching the registry etc to a file during shutdown. Part of the metadata about the state of all mounted partitions at the time of turn-off, is among these system information. This reduces the boot time of the Windows 8 but it creates the trouble for Ubuntu.Since the information about the NTFS partition is stored in Windows 8, this prevents Ubuntu to mount them as mounting them in Linux will alter the metadata of the partitions. This is why it is in protected mode and you cannot mount it (without being root).

    解决办法

    1.利用ntfsfix

    sudo ntfsfix /dev/sdXY        //sdXY为出错的分区代号,比如sda7
    

    2.在windows里关闭windows的快速启动
    在电源选项里

    显示网络已禁用

    1.首先停掉network-manager这个服务

    sudo service network-manager stop 
    

    2.删除掉NetworkManager.state这个文件

    sudo rm /var/lib/NetworkManager/NetworkManager.state 
    

    3.启动network-manager这个服务

    sudo service network-manager start 
    

    如何查看系统版本号

    linux内核版本

    cat /proc/version

    Linux version 4.2.0-36-generic (buildd@lcy01-27) (gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) ) #42~14.04.1-Ubuntu SMP Fri May 13 17:27:22 UTC 2016
    

    uname -a
    此处能查看主机名

    Linux JCUAN 4.2.0-36-generic #42~14.04.1-Ubuntu SMP Fri May 13 17:27:22 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
    

    查看linux发行版本

    lsb_release -a

    No LSB modules are available.
    Distributor ID:	Ubuntu
    Description:	Ubuntu 14.04.4 LTS
    Release:	14.04
    Codename:	trusty
    

    打开文件管理器的命令

    nautilus

    如何使程序可以被ubuntu的启动器搜到

    命令行操作内容:
    cd /usr/share/applications
    vim xxx.desktop
    打开需要编辑的文本内容为:
    [Desktop Entry]
    Version=1.0
    Name=xxx
    Exec=/home/username/xxx.sh(这个是启动程序需要执行的文件路径名)
    Terminal=false
    Icon=/home/username/xxx.png(这个是图标)
    Type=Application
    Categories=Development
    

    下边是vscode的例子

    [Desktop Entry]
    Name=Visual Studio Code
    Comment=Code Editing. Redefined.
    GenericName=Text Editor
    Exec=/usr/share/code/code --unity-launch %F
    Icon=/usr/share/code/resources/app/resources/linux/code.png
    Type=Application
    StartupNotify=true
    StartupWMClass=Code
    Categories=Utility;TextEditor;Development;IDE;
    MimeType=text/plain;inode/directory;
    Actions=new-window;
    Keywords=vscode;
    
    X-Desktop-File-Install-Version=0.22
    
    [Desktop Action new-window]
    Name=New Window
    Name[de]=Neues Fenster
    Name[es]=Nueva ventana
    Name[fr]=Nouvelle fenêtre
    Name[it]=Nuova finestra
    Name[ja]=新規ウインドウ
    Name[ko]=새 창
    Name[ru]=Новое окно
    Name[zh_CN]=新建窗口
    Name[zh_TW]=開新視窗
    Exec=/usr/share/code/code --new-window %F
    Icon=/usr/share/code/resources/app/resources/linux/code.png
    
    

    更新chrome之后点击链接弹出浏览器都是空白页

    查看/usr/share/applications/google-chrome.desktop是正常的,但是在~/.local/share/applications里边还有一个google-chrome.desktop,缺少了一个%U参数

    [Desktop Entry]
    Encoding=UTF-8
    Version=1.0
    Type=Application
    Name=新标签页 - Google Chrome
    Icon=google-chrome.png
    Path=/home/jcuan/下载
    Exec=/opt/google/chrome/chrome %U
    StartupNotify=false
    StartupWMClass=Google-chrome
    OnlyShowIn=Unity;
    X-UnityGenerated=true
