Linux Kernel 3.9.7 Installation

This kernel 3.9.7 can be installed in all of Debian based Linux distributions like Ubuntu and Linux Mint. As with any core level Linux stuff, we’d recommend using it only if you wish to rectify problems with your system. Follow the procedure at your own risk. If you find any of the steps difficult to comprehend, don’t do it.

Open up a terminal window and enter the following:

  1. Make the temporary folder your current focus.

cd /tmp

  1. Run these commands one after another in that order and be patient. Let each of them complete at their own pace.

wget -O kernel-3.9.7

chmod +x kernel-3.9.7

sudo sh kernel-3.9.7

  1. Reboot your system. If you closed your terminal window already, do it the traditional way. Our way is by entering the following commands.

sudo reboot

Removing Kernel 3.9.7

We totally understand the procedure above may create more problems than it solves. So if you’re one of those unfortunate ones – we aren’t – then you could use the following command to revert to your stock kernel.

sudo apt-get purge linux-image-3.9.7*

Do let us know if it fixed any of your issues. Actually, you can tell us anything you want. We’re all friends here…
