N is nothing more.
After the installation, you can log on to the graphic interface. However, this graphic interface has many minor defects. If you don't care about this, you can start to use your minimal debian System. 2. this part is mainly about installing software to improve the defects of the graphic interface. The software to be installed mainly includes: gnome-shell-extensions, network-manager, gnome-icon-theme-extras, alsa-utils, freedesktop-sound-theme, file-roller, xdg-user-dirs the role of the software. Gnome-shell-extensions: if this software is not installed, the shutdown of the system becomes suspended. Network-manager: network management. Gnome-icon-theme-extras: some gnome icons, mainly in the file system. I don't know where else to use it. if you don't think it has any influence, you can leave it alone. Alsa-utils: If you do not have this software, after you restart the machine, you will find that your previous sound settings are gone and you need to reproduce the settings. Freedesktop-sound-theme: This software is mainly used to beep when adjusting the volume. Xdg-user-dirs: Do not manually create these folders because these folders are automatically managed by the system. if you change the system default language, the names of these folders will also change accordingly. In addition, many software settings are associated with these folders. File-roller: Right-click and unzip the compression function. if you use the command line to perform these operations, this is unnecessary for you. Now start to install some software that I think is necessary. 3. gedit, gnome-terminal, fcitx, fcitx-table-wbpy, locales, and sudo) gedit, gnome-terminal, fcitx, fcitx-table-wbpy, and locales. I will not talk much about sudo. everyone knows what it is. 4. perform some configuration now. First install ttf-wqy-zenhei on my computer. if this gnome-terminal is not installed, the words will overlap. (Su party ignores) configure sudo: vi/etc/sudoers to replace xxx LL = (ALL: ALL) ALL xxx with your user name under root ALL = (ALL: ALL) ALL. Dpkg-reconfigure locales: set the system language.
