I found five changes among these I would want for my Debian system. You must agree, that’s an impressive list of changes…
Installation of Kernel 3.12
The process lets you manually install the kernel on your Debian based system which includes Linux Mint and Ubuntu. The process is pretty fool-proof and two of our systems have successfully accepted its new kernel. However, we urge you to exercise reasonable precaution. Read it twice before starting. It’s all on you…
1. Launch the terminal
We like using [Ctrl][T]. But you can go through the longer route if you like.
2. Enter the commands
The commands have to be entered in the terminal precisely, in the exact order one after the previous is complete.
Focus on the temporary folder
Download the latest kernel
wget http://dl.dropboxusercontent.com/u/47950494/upubuntu/kernel-3.12 -O kernel-3.12
Install the freshly downloaded kernel
chmod +x kernel-3.12
Apply the kernel
sudo sh kernel-3.12
3. Restart your system
If your terminal continues to remain in view, enter the following command. Else, you can do this in the traditional way at your earliest convenience.
And that’s it. You now have a system with a fresh and stable new kernel. Enjoy!
Uninstalling Kernel 3.12
Being a stable release the kernel is guaranteed not to cause any trouble but there is a remote chance you might not like the reformed system. If you wish to roll back, all you need to do is enter the following command in a terminal window and you’re done.
sudo apt-get purge linux-image-3.12*
So, do tell us if you’ve found any improvements we might add to our unofficial change-log summary. Other than that, you can always contact us about things you’d like help for…
