How to change Ubuntu Desktop to Ubuntu Server

Go to the Ubuntu official website to see several versions that can be downloaded: alternate (Text installation), desktop9 (desktop), netbook (netbook), and server (server ).

Reasons for using server:

32-bit systems can use 4 GB memory or above, up to 64 GB. The premise is that the motherboard supports

Note.
32-bit system, after the memory ing function is enabled, the system will not be able to use the sleep function (sleep is different from the standby)

The driver may not be compatible with the server version !!!

I have encountered compatibility issues with ATI graphics cards. Don't ask me what to do.

Unlike windows, you do not need to download Ubuntu Server again. You only need to install the Server kernel.

To install the server kernel, it is easy to call the terminal input:

Sudo apt-get install linux-image-server linux-headers-server linux-server

(I have already installed it, but I still want to demonstrate it)

How can I confirm that I have used the server kernel?

Restart after successful installation

Terminal input uname-

Here I show:

Www.linuxidc.com @ Ubuntu :~ $ Uname-

You can see that you have used the server kernel Linux Ubuntu 2.6.38-8-server.

If the server is not used, uninstall the original kernel.

If you open your familiar Vmware, the following prompt appears:

"Before you can run VMware, several modules must be compiled and loaded into the running kernel.
Kernel Headers linux-headers-2.6.38-8-server

Please upgrade your VMware first (Take A Look At The http://blog.csdn.net/luozhuang/Article/details/6601251) then

Sudo apt-get install linux-headers-server
