specially if that kernel is said to be safe on ubantu and debian base would that be stable for mint to. If while testing any thing goes wrong how can i revert to old kernel, debian is using 3.16.3 and ubantu 3.16 in their stable version, Anybody tried any kernel plz enlighten me. I am using Lenevo g580 , 4gb ram, 1tb hdd, radeon 4000 inbuilt graphic card so which one should be fine with me. Are the 3.13.37 reccomended kernel ok or is it has same risk as other I purchased this laptop back in 2012 so what do you say

If the Ubuntu or Debian kernel is available through Linux Mint's Update Manager (in Linux Mint 17.x, in Update Manager's View menu you'll find the Linux kernels option to install newer kernels) it is generally safe to upgrade, as long as you know how to revert to the older kernel. Say something doesn't work right with the new kernel and you can't boot your system. You can boot with the older kernel by selecting that option from GRUB boot menu.

There may be problems with proprietary drivers not supporting newer kernels yet (e.g., AMD or Nvidia graphics cards if you aren't using the default open source drivers). I think upstream Ubuntu has improved how they handle kernel updates to account for that situation.

If it ain't broke though, don't fix it :wink:

debian is using kernel 3.2 ( https://packages.debian.org/search?sear ... .0-4-amd64 ) not 3.16 in the stable release (wheezy).

LMDE 2 is based on Debian Jessie (next-stable, release imminent) and uses 3.16 kernel.

I've had pretty good luck installing later kernels from other distros:
Ubuntu 4.0 kernel into Debian8
Debian 3.19 'trunk' kernel into Debian8
and

Code: Select all

$ uname -a
Linux lemurator17 3.19.0-9-generic #9-Ubuntu SMP Wed Mar 11 17:50:03 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
...Ubuntu 3.19 kernel into Mint 17.1. It's from Ubuntu 15.04 "vivid".

Main problems will be nvidia drivers and virtualbox (have to reinstall afterwards), which I couldn't get to work with kernel 4.0

well you may be right but I was getting the reference from the distrowatch reference chart for ubantu and debian you may have a look over there and then tell me :wink:
