Successfully installed and configured UbuntuLinux.

It was too difficult. After a long struggle, it solved the problem that nvidia graphics card drivers could not be identified. The include file could not be found in gcc compilation; playing mp3 files; Chinese font installation and Chinese environment configuration; installation of scim Chinese Input Method; playback of avi and mpeg files; playback of rm and rmvb files (and playback of images without sound. Now my Ubuntu can gradually replace Windows! Now I will post these things to share with you the following: nvidia graphics card (g is too difficult, after a long struggle, it has solved the problem that the nvidia graphics card driver cannot be identified; the include file cannot be found for gcc compilation; playback of mp3 files; installation of Chinese fonts and environment configuration; installation of scim Chinese Input Method; playback of avi and mpeg files; rm, rmvb format file playback (and can play images, but no sound) and other issues. Now my Ubuntu can gradually replace Windows!

Now I will post these things and share them with you:

Nvidia graphics card (go 7300) DRIVER:

Install all updates (I think some lib components need to be re-installed), download the corresponding nvidia driver, and log out of the graphic interface;

Switch to the command line terminal;

Sudo/etc/init. d/gmtsstop disable the graphic interface;
Sh ...... (Corresponding driver) install the driver, do not download, allow compilation;

Restart; Enable restrict devices manager to view the corresponding icon and activate it. Restart (you can log out and start again on the Internet. However, I seem to have encountered an installation failure, and the GUI cannot be started any more. For security reasons, restart ).

The include file cannot be found during gcc compilation (for example, stdio. h)
This is simple: sudo apt-get install build-essential

Mp3 format file playback
I have never been able to find any codecs of thy. Instead, I installed an xmms: sudo apt-get install xmms.

For details about the configuration of the Chinese environment and Chinese environment, and the installation of scim and scim-bridge, refer to the official Ubuntu wiki. It is very detailed and practical. I feel more practical than others, and it will be successful once.
