This step by step howto covers compiling Linux kernel version 5.1.14 under an Ubuntu or Debian Linux.The following instructions successfully tested on an RHEL 7/Cent OS 7 (and clones), Debian Linux, Ubuntu Linux and Fedora Linux 28/29.After installing the newest kernel a dozen times you will ask the question " this will give you a very big output.Now chose one of them that you want to install and install it by following commands(Don't type these commands like this,replace the word kernal_version with the kernel version which you wish to install) Now when I first did it, I Don't know is it my hardware problem or because of removing the old kernel,but my laptop shows me black screen which happens to my laptop sometimes.Another option is to try customized and optimized builds, such as this i3/i5/i7 optimized 3.2.1 kernel for Ubuntu: Duo Petal Flower, My Experiments with Linux - 3.2.1 kernel He also has Intel atom optimized builds which can work quite well if you're trying to squeeze every last ounce of performance out of a netbook.There are other kernels like Liquorix that claim to be better optimized for desktop performance.You can give it a try, it's on github, please be sure to read the README.ompiling a custom kernel has its advantages and disadvantages.
