I'm using elementary Freya.

Is there any way to upgrade the Linux kernel to 4.0?

And by upgrading kernel can we download and install packages from elementary ppa ?

  • In your last sentence, do you mean “can we upgrade the kernel by installing a PPA?”, or “if I upgrade the kernel, will that let me use PPAs”, or something else? Commented Jul 1, 2015 at 18:19
  • Out of curiosity, what are the advantages of using the 4.0 kernel?

  • @waldyrious power Improvements, hardware improvements, new drivers and performance tweaks and so on. Commented Jul 1, 2015 at 19:02
  • @Gilles i mean “if I upgrade the kernel, will that let me use PPAs” Commented Jul 1, 2015 at 19:04
  • @Saeed Ok, then to answer that: no, upgrading the kernel will not have any impact on your ability to use PPAs. Commented Jul 1, 2015 at 19:06

1 Answer 1

  1. Access the Ubuntu kernel PPA mainline repository here.
  2. Download the following:

  3. cd into the download directory and run

    sudo dpkg -i *.deb

On reboot your system should boot the latest kernel. You can test this by running uname -r. Note that this will not automatically update from this point forward (in particular, you won't get any security fixes), and that this is not supported by elementary.

As for your question about PPAs: installing a newer kernel will not change anything about your ability to use PPAs.

  • He asked for 4.0. I wouldn't try on 4.1 just yet. Other than that, yes try the above instructions.
