I'm running Ubuntu 12.04 with kernel 3.5.0-52-generic (64 bit), the desktop version, have dkms installed, one HD7970.

I got an update note (https://wiki.ubuntu.com/1204_HWE_EOL) and am wondering what to do. Knowing that it's not recommended to run 14.04 I'd like to stay with my running 12.04 LTS.

Here's what I got running
hwe-support-status --verbose

Your current Hardware Enablement Stack (HWE) is going out of support
on 07.08.2014.  After this date security updates for critical parts (kernel
and graphics stack) of your system will no longer be available.

For more information, please see:

To upgrade to a supported (or longer supported) configuration:

* Upgrade from Ubuntu 12.04 LTS to Ubuntu 14.04 LTS by running:
sudo do-release-upgrade -p


* Install a newer HWE version by running:
sudo apt-get install linux-generic-lts-trusty libgl1-mesa-glx-lts-trusty xserver-xorg-lts-trusty linux-image-generic-lts-trusty

and reboot your system.

Is "Install a newer HWE version" the solution I want?

Sorry for the question, maybe it's stupid but I don't want to screw up my perfect running system.

Thanks, v.
i haven't tested the saucy or trusty backports, but the raring backports work well.

aptitude -R install linux-generic-lts-raring xserver-xorg-lts-raring xserver-xorg-core-lts-raring xserver-xorg-input-evdev-lts-raring xserver-xorg-video-dummy-lts-raring libgl1-mesa-dri-lts-raring libgl1-mesa-glx-lts-raring

i'm assuming the saucy backports work well, but i don't know. i probably wouldn't install the trusty backports since current stable Catalyst doesn't officially support trusty.
Thanks a lot for your help! Glad I asked ;-)
