Linux-ubuntu16.04 kernel compilation,

In order to adapt to the new hardware and driver requirements, try to recompile the kernel. Use ubuntu16.04-LTS to compile.

1. Replace the Linux software source to improve the download speed:

Edit the path vi /etc/apt/sources.list

//full text delete command

:.,$d

Or you can try to change the source manually, it may be more convenient: select 'Other site'

2. Create a new root user:

sudo passwd root

su to enter root privileges

3. Download the source code to /usr/src:

apt install linux-source

4. May be used to give folder permissions 

chmod 777 -R path to give to file

5. Unzip the source code

tar xvf linux-16.04.tar.xz2

6. Compile 

apt-get install libncurses5-dev  //安装curses
Enter the decompressed source package and execute the command make menuconfig

Enter the configuration interface for relevant configuration, and attach detailed instructions for ubuntu kernel compilation: click to open the link (thanks to God for organizing)

7. After configuration, try make

Error reported missing header file openssl.h Command: apt-get install libssl-dev
Re-command make bzImage	

Enter the long wait. . .

After the compilation is completed, check the storage path of bzImage. Here I am /usr/src/linux-source-4.4.0/arch/x86/boot/bzImage

8. Replace the kernel

Copy bzImage to the mounted system and place it in the boot directory. Add kernel options: open /boot/grub, edit the file menu.lst

Add: title U
      kernel /boot/bzImage rw vga+771 panic=1 root=/dev/sda1 hpet=disable
      savedefault 0

Save and restart, select U in the startup interface to enter the new interface.

PS: 1. Delete unnecessary configuration files: sudo make mrproper    For a kernel just downloaded from the Internet, it must be clean, doing so will only be superfluous. But it's a good habit, and there are no bad consequences. 2. Install header files # sudo apt-get install linux-headers-4.4.0 Example of uninstalling header files # sudo apt-get remove linux-headers-4.4.0
