Hi Hrushit,
I am trying linux kernel hacking for the very first time and following the FirstKernelPatch tutorial.
On compiling, installing and rebooting from the kernel I get a blackscreen and I do not get my Ubuntu login screen or any display. I can get to a
bash prompt with ctrl+alt+F1.
Since you are using ubuntu I recommend distro specific kernel compilation steps because following the manual steps sometimes does not work. Though i recommend you learn them. :).
Next time also try to mention the Ubuntu version you are using.
The linux kernel of my repo is 4.5.0-rc+. I copied the existing .config file from /boot to my source tree and ran 1. make olddefconfig, 2. make 3. make modules_install install.
Try the below steps let me know if it works for you,
1. Copy old configuration cp /boot/config-`'uname -r ` ./.config (Use old configuration to built the kernel) 2. Clean Working Directory "make-kpkg clean". 3. Compile the Kernel
"export CONCURRENCY_LEVEL=3" ( For parallel builds, faster compilation).
"fakeroot make-kpkg –-initrd –-append-to-version=-some-string-here kernel-image kernel-headers" (In append-to-version please mention the name you would like to give your custom kernel)
4. Install the kernel "sudo dpkg -i linux-header.deb" "sudo dpkg -i linux-image.deb"
5. Restart the kernel.
Finally compile the kernel in home directory don't use sudo except for installing the kernel.
