Upgrading kernel to 3.14/3.15 etc.?

Postby nobodynoze on Sat May 03, 2014 8:49 pm

I'm just wondering which kernel upgrade method is recommended.

I figure using Debian's unstable/sid kernel? Liquorix kernel?

If I wanted to use 3.14, for e.g., I could change my sources list or is there a command to only install a newer kernel? Then, when it's in the repo, I upgrade it by booting up a different grub entry?

I'm not familiar with kernel upgrades but would like to try.

Using the Liquorix-Kernel is the best and easiest way, to upgrade the Debian Kernel.
For getting the most 'stable' kernel, that made for Debian

Liquorix Kernel Project > http://liquorix.net/

Presently, I use the 3.14.2 'stable' Kernel for my LMDE.

I use Liquorix 3.13. It's fast and stable. I had problems with Liquorix 3.11- 3.12 with LMDE (breaks hibernation), but the situation is fixed in 3.13+.

In particular, my version is 3.13.9-liquorix-lxc-20140414

Liquorix doesn't have everything for cgroup to support lxc, so I patched lxc support off the Liquorix 3.13.9 kernel.

BTW, you can either download kernel deb from the site someone posted above, or you can add a sources.list like the site mentions to add the kernel to your system.

nobodynoze, be careful when upgrading your kernel if you use proprietary drivers for graphics. Remember you should build them again against the new kernel. If you don't do it, next reboot will direct you to TTY :wink:

Hi, I want to bump this (my?) thread to ask some more questions. :)

I am currently using 3.14.3. I am just curious of the ways to upgrade the kernel still although it sounds like the best ways or methods are either the Liquorix kernel or using the kernel from the actual kernel website:
https://www.kernel.org/

If I use the 2nd method, it's just a generic kernel, not compiled specificly for Debian (or LMDE, obviously), correct? Whereas, the liquorix kernel is (i.e. choosing the one for Debian, not Arch, of course)?

I read a post here:
viewtopic.php?f=197&t=139025

Could I use those steps (in theory) but of course, substitute the download for the desired kernel (for e.g., 3.15.5)?

I am curious about this topic especially after reading this thread:
viewtopic.php?f=199&t=172083

I found it very interesting. ;) That's my dilemma (always). I like using more recent software so I often use(d) Debian Testing. It's why I tried LMDE in the first place. I am lazy (I guess) so LMDE looked a bit more polished (and a bit less work - also has Firefox and Cinnamon/MATE choices - wasn't available for Debian then). But, I'm reading keeping up with Testing might be easier with KDE or XFCE than Cinnamon.

I guess one could add the Debian Testing repo and then use Testing/Jessie or sid kernel/headers etc., too?

Most of the how-tos' for upgrading the kernel is almost always geared towards Ubuntu. At least, all that I come across. They list Debian but then you notice they are Ubuntu-based and often include Ubuntu ppa etc.. They would work but it should be mentioned.

Thoughts on that? I know hard-core Debian users would shun that. :) But, it's another option? I guess using Liquorix is probably the easiest but is 3.15.5 available? Not sure they are always up to date? I notice a patch for 3.15.5 so does that mean 3.15.5 is one of the choices? So long since I've used / tried using Liquorix. Their scripts sometimes gave me trouble (in the past) and some Debian-based distros don't support using sxmi or whatever it's called.

Comments? I hope my updated post is still interesting. ;) Thanks for the replies.

I forgot to reply to this. :) Ooops. Yeah, as of this post, I am using the nvidia proprietary drivers (Nvidia Server Settings got added to only 'All Applications' for some reason). Version 337.19 is installed as of now.

I often have issues/problems even though I know that the proprietary drivers need to be built against the new kernel. :) Usually, I get it sorted out eventually, though, but the trials can get a bit frustrating, sometimes. :)

This is how I get the latest kernel, headers, drivers, etc from Debian Testing:

su -c 'echo deb http://http.debian.net/debian testing main contrib non-free > /etc/apt/sources.list.d/debian-testing.list'

apt update

Install via Synaptic Package Manager

sudo rm /etc/apt/sources.list.d/debian-testing.list

apt update

Hi,

it is always safe to stay within same relase of the kernel 3.14.a to 3.14.x does improve
jumping to another version like 3.15 could break the system also the major changes on it may not even be supported on your hw, so benefit would be zero and a lot of hassle for nothing.
People disagree with me. I just ignore them.

The latest kernel in Debian Testing is 3.14-1 I think.
