Ubuntu installs a custom Linux kernel

How to install a custom Linux kernel Linux kernel is the heart of the http://www.aliyun.com/zixun/aggregation/13835.html ">ubuntu operating system." Ubuntu's own kernel usually contains all the drivers you need, but sometimes you want to tweak your kernel or if you need to recompile for specific reasons, this manual will help you. Like this less detailed document can actually be found in the kernel compilation Guide.

To create the kernel, you need to build-essential Fakeroot and kernel-package packages.

bash:~$ sudo apt install build-essential fakeroot kernel-package

The kernel creation work is done in the/usr/src/directory, so adding SRC groups

bash:~$ sudo adduser my_username src
Adding user my_username to group src ...
Done.

Log off and log in again, or use Su to log on (toggle user):

bash:~$ su my_username
bash:~$ groups
My_username SRC Audio adm dialout cdrom filename video Plugdev

All group names are listed, and SRC is one of them.

Get Source code

You can search the kernel source code in the following way

bash:~$ Apt-cache Search Source 2.6

Select the kernel source code you want.

Problem: The kernel source code sometimes called kernel-source-2.6.5, and sometimes called linux-source-2.6.8.1, why?

Kernel-source from Debian,linux-source from Ubuntu. If possible, try to use Linux-source. All dependencies have not changed, though, and you can safely ignore them if you get an error warning like "uninstalled package Kernel-source" (Linux-source kernel source pack) via the '--bronson '.

Download the kernel source code using the following commands:

bash:~$ sudo apt install linux-source

It is recommended to install Libncurese-dev and Libqt3-dev packs, the first one is required by Menuconfig, the second is for Xconfig, and one of them is very small (see below)
